NARRATOR: Ancient ruins submerged

for thousands of years.

Alien creatures lurking beneath our seas.

And unidentified objects emerging

from the depths of the ocean.

For nearly two decades,

Ancient Aliens has traveled the globe

exploring towering megalithic structures,

mysterious artifacts

and stories of otherworldly beings

in a quest for evidence that might reveal the truth

of our extraterrestrial origins.

It's fascinating to think of stories from around the world

of disc-shaped craft coming up out of the water.

NARRATOR: Now we take a look back

through the Ancient Aliens archives

to the show's very origins

to examine the evidence that we are not alone.

We have never been alone.

♪ ♪

You know, on Ancient Aliens, we often talk about

what people have seen in the sky,

but there are many accounts of strange beings and craft

coming up out of the water.

Yeah, and when you consider the fact

that two-thirds of our planet is covered in water,

you have to imagine that there are things

hidden in the oceans and lakes that we know nothing about.

In fact, we're finding entire cities

in the depths of the ocean.

Oh, absolutely.

That's why we start this episode with Atlantis,

the legendary island that sank into the ocean.

And let me tell you, if we find Atlantis,

then I know we'll find more proof of ET visitation.

We covered it in season two in "Underwater Worlds."

NARRATOR: Covering more than 71% of the planet,

the Earth's oceans are a vast and largely unexplored mystery.

For most of recorded history, man could only guess

at what lay beneath the ocean's surface.

But new technologies are reaching new depths.

Researchers around the world are finding the unexpected:

underwater complexes and sophisticated monuments

that defy the conventional historical record.

MICHAEL CREMO: There are remains of urban civilizations

on parts of the Earth

that were exposed on land

10,000 and more years ago.

And this means that urban civilization

is far older by many thousands of years

than many scientists now believe possible.

NARRATOR: Scientific theory suggests

that during Earth's last ice age,

ocean levels were once much lower than they are today.

GRAHAM HANCOCK: You have to envisage a world

in which there are two-mile-deep ice caps

sitting on top of Northern Europe

and North America

in which are accumulated enormous quantities of water.

And we know that this water began to melt

about 21,000 years ago

and finished melting about 10,000 years ago.

NARRATOR: As a result, rich coastal lands

were slowly submerged by rising sea levels.

Ten million square miles of land was flooded

all around the world.

That's roughly the size of Europe

and China added together--

were just rubbed from the record.

They just disappear from the story.

And in my opinion, archaeology is not doing

enough work to investigate those lost and submerged lands.

♪ ♪

NARRATOR: While much of the ocean's floor remains unexplored,

for thousands of years,

philosophers and scientists have been drawn

to one of the greatest mysteries of the sea,

the legend of the lost city of Atlantis.

DAVID CHILDRESS: It's been said that more books

have been written about Atlantis than any other subject.

But most of what we know comes from

the Greek philosopher Plato,

who wrote two books about Atlantis,

the Timaeus and the Critias.

NARRATOR: Written in 360 BC,

Plato described Atlantis as a highly advanced city,

ringed by concentric walls,

which flourished 9,000 years before his own time.

CREMO: There are descriptions

of huge palaces for kings.

It's stated that Atlantis had huge naval forces,

which it used to conquer other parts of the world.

It was an urban civilization.

According to the ancient Greek texts,

Atlantis was connected

with extraterrestrials from the beginning.

It was founded by the Greek god Poseidon.

♪ ♪

Poseidon can be regarded as an extraterrestrial

in the sense of not being of this Earth.

NARRATOR: According to the legend,

after a failed attempt to invade Athens,

disaster struck the island.

According to Plato, Atlantis was destroyed

in a day and a night...

...in a cataclysmic destruction

that sank the entire island

and its capital city.

Some researchers believe

that the Atlanteans somehow destroyed themselves.

NARRATOR: According to Plato, Atlantis was located

in front of the Pillars of Hercules,

a location beyond what some scholars attribute

to modern Gibraltar.

CHILDRESS: And to the ancients,

as they left the Mediterranean Sea

to go into the larger Atlantic Ocean,

this was where they went beyond the Pillars of Hercules

between Spain and Morocco.

NARRATOR: Across the Atlantic lies the island chain of the Bahamas,

just southeast of Florida.

Here in 1968,

archaeologist J. Manson Valentine believed

he found part of Atlantis when he discovered

an unusual rock formation off the coast

of North Bimini Island.

JOHN VAN AUKEN: It's only in about 12 to 18 feet of water,

so you can, uh, view it easily.

First, scientists thought this was just beach rock,

but then several other scientists

exploring the Bimini Road noticed

that the beach rock was on top of other beach rock,

with balancing stones wedged in between.

And they said, "Nature doesn't do that.

Man does."

And they realized this is a harbor,

a breakwater for a harbor.

From the shallow edges of Bimini

all the way to the Gulf Stream in 300 feet of water,

we have found many fascinating complexities

that look like remnants of ancient cities or structures:

roads, pathways, structures covered in coral.

NARRATOR: Could the Bimini ruins be remnants of Atlantis?

And if so, could these roads lead to other sites

buried under sand and water?

♪ ♪

In the year 2000, while mapping the seafloor

off the western coast of Cuba, a research expedition

led by Russian-Canadian oceanographer Paulina Zelitsky

spotted symmetrical stone structures

deep below the water.

Remarkably, they were over a half mile down.

PAULINA A. ZELITSKY: Divers cannot do this kind of investigation,

so we have to use remote operated vehicle.

And this vehicle is equipped

with video cameras and manipulators.

And it's controlled from the deck of the ship.

NARRATOR: The expedition was also armed

with side-scan sonar equipment used to create images

of large areas of the seafloor and underwater objects.

I was in control room on board of the ship,

and we were receiving that image coming from side-scan.

And this is just one of the many other images

that we were obtaining of the 80, uh, structures

made of large stones

placed one on top of another.

♪ ♪

LINDA MOULTON HOWE: Well, what do they end up with?

It is an image that shows these rectangular,

90-degree angles over and over and over

on very large structures that seemed to have wide avenues.

NARRATOR: The exploration found

huge stone blocks in pyramid shapes,

others more circular.

Most were gigantic, reaching 16 feet in height

and weighing several tons.

30 geometric structures emerged,

appearing to be the remains of streets,

buildings, tunnels and pyramids,

all at a depth of 2,200 feet below the surface of the water.

ANDREW COLLINS: We might well have here

the evidence of a prehistoric culture

that would probably go back tens of thousands of years.

And that's very exciting indeed.

NARRATOR: Using dating techniques based on

the presence of nearby volcanic ash,

geologists estimated the underwater city sank

over 6,000 years ago.

HOWE: Could this be, a half mile down,

some part of the sunken Atlantis

from 9,000, 10,000 years ago that Plato talked about?

COLLINS: Well, the Atlantis myth is integrally related

with the area of the Caribbean and the Bahamas,

in particular Cuba.

Plato talks about an island empire.

He's probably talking about dozens

of different islands of different sizes,

not just in the western Atlantic but probably stretching out

right into the central Atlantic area.

NARRATOR: Both the Cuban and the Bahamian ruins

lie on the western edge of the Bermuda Triangle,

an area of ocean covering over 500,000 square miles,

known for magnetic anomalies,

extraterrestrial sightings

and unexplained disappearances of aircraft and ships.

Could there be a connection between Atlantis

and the area known as the Devil's Triangle?

BILL BIRNES: On the edge of the Bermuda Triangle,

there are underwater ruins

of the ancient city of Atlantis,

the prehistoric city of Atlantis.

So, yes, there is a theory that Atlantis lies

not near Greece but in the Bermuda Triangle.

NARRATOR: If Plato's texts are true,

then other Greek myths may provide a hint

of the true fate of Atlantis.

One myth tells of the Titan goddess named Asteria...

...who fell from the sky and became an island.

TSOUKALOS: In ancient Greece, we have a number of myths

which describe islands,

bronze, gleaming islands

that fell from the sky and landed in water.

I don't think that Atlantis, therefore,

was an actual stationary, physical island.

Atlantis, according to Plato, disappeared in one night

with a lot of fire and a lot of smoke.

See, I don't think that Atlantis sank.

I think Atlantis lifted off.

♪ ♪

NARRATOR: Was Atlantis a safe haven for ancient aliens

before the end of Earth's last ice age?

And if so, could there be other alien cities

submerged deep underwater?

NARRATOR: Yonaguni, Japan.

This small island is at the westernmost tip

of the Japanese archipelago.

Scholars believe the first inhabitants migrated here

from Southeast Asia during prehistoric times.

In 1987, in nearby waters,

dive tour operator Kihachiro Aratake

made a shocking discovery.

A massive complex of stone formations

lay hidden a mere 60 feet beneath the ocean surface.

Experts call it one of the greatest discoveries

in the history of underwater archaeology.

HANCOCK: What's intriguing about the complex at Yonaguni

is that there are a whole range of monuments

pretty much side by side.

And this, to my eye,

looks unmistakably to be the work of human beings,

not the random action of the ocean

on differential layers of stone.

(speaking Japanese)

(translated): There are several reasons why I think this is not

a natural formation.

A number of tools and numerous engraved stones

were found at the site.

Because of these things, there is no doubt to me

that this was made artificially.

NARRATOR: Submerged beneath 60 to 100 feet of water,

the largest of the formations

resemble a massive five-layered stepped pyramid,

the size of two football fields.

WILCOCK: You see unambiguous carvings

that clearly are geometric in nature,

tons of right angles.

We see channels that you can walk through

with stairwells at the end

that are perfectly rectangular in shape.

There are places where you find megaliths

piled on top of one another

to create a tunnel through which you can swim.

There's a set of megaliths positioned side by side,

uh, against the side of the cliff.

There's a gigantic human face carved underwater.

(translated): There is a stone in which is carved

a face almost 23 feet tall.

Our first impression was that it looked

a lot like the moai on Easter Island.

Then we began to realize that it strongly resembled the Sphinx,

which guarded the pyramids.

We wondered if that might be the function

the face is also serving here.

HANCOCK: It's the whole combination of all these structures together

which convinced me that we're looking at a ceremonial complex.

The mystery surrounding the-the Yonaguni underwater structure is

when did it go underwater?

The geological evidence is that it was submerged

during the meltdown of the last ice age.

All around the world, whether it is France,

India or Japan,

there are man-made structures that lie underwater.

Two ways how our ancestors could've done this.

Either they had scuba gear-- I don't think so--

or this stuff was built

when the ocean levels were lower

and that was over 14,000 years ago.

And 14,000 years ago,

according to mainstream archaeology,

we were just dwelling in caves, hunter-gatherers.

NARRATOR: Could the Yonaguni structures have been built

by such primitive people?

And what evidence exists of the people

who inhabited this island?

(translated): Human fossils were found,

so I'm sure there were people living on the island.

But there's some question about whether or not

they had the technology to create structures,

or anything like this.

HANCOCK: It's not so much the question of could the stone

have been chipped away and removed.

It's a question of the-the vision,

of the scale of the complex,

of-of thinking in those kind of terms.

And we know of no other, uh, Stone Age culture

that thought in those kind of terms,

of creating a gigantic, uh, seemingly ceremonial complex.

NARRATOR: If, according to scholars, the ancient Japanese people

could not have built this monument, who did?

And how did it get here?

BIRNES: The speculation is that extraterrestrials

created the Yonaguni monument.

The engineering is just beyond the capacity

of Stone Age civilizations.

NARRATOR: Ancient astronaut theorists also believe

the key to the Yonaguni mystery

is found in its global positioning.

Strangely, the complex lies within an area of the Pacific

long suspected of extraterrestrial activity.

It's called the Dragon's Triangle.

Just south of Japan, you have a mysterious area

called the Dragon's Triangle,

which is very similar to the Bermuda Triangle

because you have planes that have disappeared from the air,

ships that have disappeared from the ocean.

In fact, Japan has declared this a disaster area.

Don't fly through it.

Stay the heck away because if you go in there,

terrible things can happen to you.

(pinging)

BIRNES In ancient Japan and even into the relatively modern era,

there are stories about the Dragon Sea,

in which objects rise out of the water

and sail through the air.

In ancient Japan, these were winged monsters breathing fire.

In more modern times,

these took on the appearance of actual machines.

When you compare those descriptions

of these devices with the description

that Columbus gave of a craft, nearing the Bermuda Triangle,

actually rising out of the water,

a light that followed the ship,

you realize there's a similarity

in both of these locations to things, objects,

that are in the water,

and rise out of the water and fly through the air.

NARRATOR: But why are the two submerged structures

found within the perimeter of these strange regions

of the planet where so much unusual activity occurs?

Is it coincidence that the Earth's 25th parallel north

cuts through both the Bermuda Triangle

and the Dragon's Triangle?

BIRNES: They lie on a plane, along the same line,

and both of them have the same magnetic phenomena,

in which compass bearings are lost and instruments go down.

(alarm blaring)

People wonder if there's a real strange UFO connection.

GIAN QUASAR: If UFOs and flying saucers do exist,

then we should suspect that they could

originally come from an ancient super civilization.

It makes you wonder if flying saucers, UFOs--

whatever you want to call them--

actually use the area of the Triangle as their major base,

and perhaps are even coming back to the remnants

of a civilization that they were familiar with.

NARRATOR: What if the sunken monuments at Yonguni

and near Cuba had alien origins?

Might they have been used as alien bases?

And if we believe

extraterrestrials functioned on land,

could they have also functioned underwater?

Could there be more evidence lying in the vast Pacific?

When we talk about things hidden in our oceans,

it's fascinating to think of stories from around the world

of disc-shaped craft coming up out of the water.

Yeah, and these stories have happened throughout history.

One of my most favorite comes out of Japan,

where a craft washed up on shore and it is said

that it had strange inscriptions all around it.

Yeah, and they said there was a being inside the craft

-holding some kind of a box. -Mm-hmm.

And this was documented by multiple witnesses.

NARRATOR: As an island nation, it should come as no mystery

that much of Japan's rich history

is tied to the waters of the Pacific Ocean.

But although many of Japan's legends

are largely unknown to the West,

some are drawing the attention of ancient astronaut theorists.

One such legend dates back to 1803,

and traces its origins to a beach north of Tokyo.

Allegedly, a craft that was quite large in size

washed up on the shore in Japan.

A strange round ship drifted ashore in this area and, uh...

The woman did not speak any language they could identify.

There were written inscriptions inside her craft

that they could not identify

and she's clutching this box

that she didn't want anybody to touch.

TANAKA:

NARRATOR: Known as the legend of the Utsuro-bune,

or "hollow ship," the details of the story

have puzzled historians for centuries.

Where, for example,

did the mysterious hollow ship come from?

Could it have come from the area

of the submerged Yonaguni monument?

Who was the strange woman?

And what were the contents of the box

she guarded so carefully?

Was it a human head?

Or was it, as some ancient astronaut theorists believe,

a type of brain or other form of extraterrestrial intelligence?

If so, could it have been intended as a gift

to the early Japanese by an ancient space traveler?

There's five different drawings that have survived

from completely different regions of Japan--

they're almost identical to modern UFO reports.

TANAKA:

NARRATOR: As evidence to support their claims,

ancient astronaut theorists point to

early Japanese carvings and statuary,

each suggesting a variety of extraterrestrial encounters.

This is a dogu figure and it comes from Japan.

And even to the untrained eye, you look at this

and it's as if this being is wearing some type of a suit,

with a helmet, some goggles.

On the back, there are all these weird buckles

and circles, you know, straps.

Very similar to a modern-day space suit.

In my opinion,

this is a likeness of a possible extraterrestrial

that visited Earth thousands of years ago.

(indistinct radio chatter)

NARRATOR: Archaeologists have catalogued the existence

of more than 15,000 dogu figures

made during the Jomon period of prehistoric Japan

dating from approximately 14,000 to 300 years BC.

But could, as ancient astronaut theorists believe,

these strange dogu figures

really be a primitive interpretation

of a pressurized space suit or diving apparel?

The story behind those dogu figures is very clear

and anyone can go and read translations

of the ancient texts that the dogu,

a long time ago, descended from the sky

and taught the first Japanese people

in various disciplines.

And the whole Japanese culture,

including the kimono and the tea ceremony,

the use of wasabi and ginger for eating sushi,

the way that they build their architecture,

their written language, everything, they say,

came from these visitors,

from these gods from the universe.

VON DÄNIKEN: The picture shows beings who look like astronauts,

they are dressed like an astronaut.

They have the helmet as an astronaut.

They have some strange tools in their hands,

tools which we do not understand.

Now there is a link, the Japanese call it dogus.

In North America, we have still the Hopi tribe in Arizona,

and the Hopi Indians

are still making today kachina dolls.

Kachina dolls look similar to the Japanese dogu figures.

Further back, in the Sahara Desert, Africa,

we found cave paintings.

When you see the picture, you see definitely

an astronaut suit, no doubt, absolutely.

Now, you compare these cave paintings

with the kachina dolls of the Hopi

and with the dogu of Japan.

You have one line.

NARRATOR: Do the mysterious dogu figures

provide tangible evidence of extraterrestrial encounters

in Japan's ancient past?

And does the legend of the Utsuro-bune

suggest that the Earth's oceans

may be hiding even more proof of alien contact?

Perhaps further clues can be found

by examining ancient accounts

detailing otherworldly entities

that inhabit our oceans.

ng

is that there are multiple ancient cultures

that describe encounters with amphibious

human-like beings.

In other words, fish people.

Yeah, like the Greek stories of the Telchines,

these fish-like beings who were sometimes described

as the children of Poseidon.

Yeah, and what's interesting is they're described

as master metallurgists with high technology.

We featured the Telchines

in a season three episode called "Aliens, Gods and Heroes."

NARRATOR: Cape Sounion, Greece.

Perched on the headland,

surrounded on three sides by the sea,

lies the ruins of the Temple of Poseidon,

built in 440 BC.

The second son of the Titan King Cronus,

Poseidon was worshipped throughout Greece

almost as much as his younger brother Zeus.

Poseidon was the god of the sea.

He was also the god of earthquakes

and, strangely, horses.

When Poseidon was in a good mood,

he created new lands out of the sea.

He gave, uh, calm waters for good voyages.

When he was in a bad mood,

he destroyed ships and brought storms.

(thunder crashing)

RADER: Poseidon does rule over the kingdom of the sea.

It is envisioned as a kind of a place where people live.

And when he comes out of that place,

yes, he rides the spectacular kind of, like, water chariot

that is driven by dolphins,

and he holds onto a really big trident.

NARRATOR: In Greek mythology,

Cronus eats all of his children except for Zeus,

who eventually rescues his siblings,

including Poseidon, from the belly of his father.

A potion is prepared that makes him heave up

all the other siblings of Zeus,

and these become the gods of Olympus.

NARRATOR: But ancient astronaut theorists

believe this Greek myth is actually a metaphor

for an extraterrestrial event.

They believe the notion of gods being vomited up

from the belly of their father

actually describes mutinous aliens

being expelled from the mother ship.

Any being which is swallowed up into a living creature

will not be able to survive for three days.

It will die from suffocation

and will begin to decay.

What we have here is not a creature,

but something else.

It could've been an object, which was clearly

of a man-made or extraterrestrial origin.

VON DÄNIKEN: A mutiny took place.

Some of the extraterrestrials, they had sex

with wonderful earthly, uh, females, women.

They were not allowed to do this.

So, one of these extraterrestrials

who were not allowed to go back with the mother spaceship

had the name of Poseidon.

Poseidon fell in love

with the beautiful human girl.

And he made her pregnant.

RADER: Poseidon is married, all right? He's got a child.

He's got some grandchildren, right?

There's the whole caste of sea nymphs as well,

all of them presumably, like, live in this place.

YOUNG: Poseidon has the power of the deep,

the-the unseen place.

If you look out at the sea, you see a surface,

and you're aware there's a whole world below that,

suggesting powers beyond that which meet the eye.

NARRATOR: Among the mythical creatures

associated with Poseidon are the Telchines,

a race of advanced "fish children."

These human-like beings

could live both in and out of water.

They are masters of technology,

and seem to match up with the fish gods

of ancient Sumeria, who worked for Enki,

the great god of alchemy and technology and smithcraft.

RADER: The Telchines are also kind of in the shadowy territory

of god, human, monster things.

They're just these kind of figures

who are not gods, but who are like human beings.

There's one story about

the Roman version of Zeus, Jupiter, trying to destroy them.

Now, we don't know whether they are actually all destroyed,

but it's possibly because of their

relationship to the magic.

NARRATOR: In Greek legend, the Telchines were also metallurgists.

They were said to have created Poseidon's magical trident

and to have cast the first bronze statues

of the gods of Olympus.

And, according to some historians,

the Telchines may not have been creatures of myth,

but were beings who actually existed.

RADER: There were people called Telchines.

We do actually have evidence of these beings.

They were actual ancient Greeks

who had specific tasks and trades

like, uh, metallurgy, like smithing, and so on.

And so, you could see how it is

that a being like the Telchines,

that these things could in fact

not just be these mythological beings

but like actual people.

So, the way that we look at the ancient Greeks and Romans

would have been the way that they would have looked at

the stories that are being told about the Iliad.

TSOUKALOS: We've got the stories of the Telchine,

and they were able to survive underwater

for unlimited amounts of time.

Now, how is such a thing possible?

NARRATOR: Could the ancient Greek myths

really be based on actual events?

Were the Telchines early humans

enabled with godlike abilities?

According to some researchers, these entities,

along with other legendary underwater creatures,

were not fictional creations,

but aliens of the sea.

NARRATOR: Miyazaki Prefecture, Japan.

May, 2014.

At the historic Miyakonojo Shimazu Residence,

the mummified remains of a sea animal

with webbed hands and feet are put on public display.

Discovered in 1818,

the bones are the first of their kind to be exhibited,

and are purported to be from the legendary Kappa,

a species of amphibious humanoid creatures

believed to lurk in the waters of Japan.

DOMINIC STEAVU: These remains were from, allegedly, a Kappa

that had been shot in 1818 near a local river.

The Kappa, which translates as,

"water child," is a creature

that is usually about five feet in height...

...has scaly skin,

and is usually blue or green in color.

It has a turtle shell on its back,

and a beak, as well as

a kind of plate on the top of its head

in which it always has to carry water.

If it spills this water, then it loses all of its power

and it can die within a very short period of time.

So, the Kappa is basically a water demon.

KEN GERHARD: The Kappa is perceived to be

a very malevolent and quite violent creature.

And, in fact,

children are warned

to stay away from bodies of water,

because the Kappa will actually

drag them in and drown them.

NARRATOR: While accounts of the Kappa are rare in modern times,

there are still sightings in remote areas

like the Fukuoka Prefecture.

In fact, to this day,

signs can be found posted near bodies of water

throughout Japan warning of the Kappa.

For ancient astronaut theorists,

the Kappa are not only real,

but their existence is proof of otherworldly beings

inhabiting the Earth's waters.

WILCOCK: These Kappa are reported

as having an unusual intelligence.

Apparently, they can speak

even though they have a bird-like beak.

And now, physical tangible artifacts

of the body of the Kappa have gone on display.

Will we find genetic markers

that clearly show that it could not be something from Earth?

NARRATOR: Could it be that the Kappa are indigenous to planet Earth,

or did they come here

by some extraterrestrial means?

Perhaps the answer can be found

by examining the many historical accounts

of mermaids.

The very earliest accounts of mermaid-like creatures

reveal a connection with beings that come from the sky.

A story from ancient Syria that dates back to 1000 BC

relates that the goddess Atargatis

came down from the sky and dove into a lake

to become a half-fish, half-human creature.

And in Greek mythology, the goddess Aphrodite

is sometimes associated with mermaid-like beings.

COLEMAN: If you look at some of the ancient classic authors

from the Greeks, from the Sumerians,

you see tales of mermaids in which there is

a very direct connection with the heavens,

with a fish-like creature that comes from outer space.

There's something out there that may not even

be connected to our known biological world.

NARRATOR: For ancient astronaut theorists,

the strongest evidence that humanoid sea creatures

not only existed, but came from somewhere beyond our Earth,

can be found in the origin tale

of yet another aquatic creature with human traits.

The West African Dogons

worship ancestral spirits they call the Nommo,

the first living creatures created by their sky god Amma.

Described as amphibious, hermaphroditic,

fish-like creatures, they descended from the stars

in a vessel accompanied by fire and thunder.

TSOUKALOS: There's a really incredible story

of the Nommo that descended from the sky

in a loud, noisy whirlwind

that made the earth shake when it landed.

And their knowledge of everything was given to them

by that being that descended in a whirlwind from the sky.

HENRY: Now this is interesting because we have

so many traditions of extraterrestrial beings

riding upon clouds that you have to ask,

did the Nommo come from the stars?

Were they extraterrestrial beings that came to Earth

to teach the Dogon?

Is this perhaps why they called them

the monitors and the teachers?

WILCOCK: The legend said they described

the star Sirius as being their point of origin

and had very accurate information

about a dwarf star called Sirius B

that wasn't even known at the time.

The Dogon said that when the Nommo landed

and came out of this craft that they arrived in,

they almost immediately got into the water.

Because they were essentially fish-like humanoids,

it seems that they needed to be in the water.

We are definitely dealing with some sort of

intelligent aquatic humanoid species

that came here as an extraterrestrial visitor

from outer space.

NARRATOR: Might the detailed descriptions of the Nommo

suggest that they were extraterrestrials

that came from space to inhabit our oceans?

And might these be the same beings

that are described in the accounts

of the Kappa and mermaids?

Ancient astronaut theorists say yes,

and suggest this otherworldly connection

may also explain the existence

of legendary sea monsters.

You knows

of these humanoid amphibious creatures around the world,

we also have stories of sea monsters.

Right, for example, these giant octopus creatures

like the kraken, or, for example,

-the Loch Ness Monster. -CHILDRESS: Yeah,

and we have reports of UFOs over Loch Ness.

So, you have to wonder if there's not a connection

between extraterrestrials and these monsters.

We covered this in a season three episode called

"Aliens and Monsters."

NARRATOR: In March 2010,

a panel of 41 international experts concluded

that the impact of an asteroid that smashed into Earth

at Mexico's Yucatán Peninsula 65 million years ago,

probably triggered the global climate change

that resulted in the mass extinction

of the Earth's dinosaurs.

But is there also evidence

that some dinosaur species survived?

And if so, might they also have evolved?

Paleontologists tell us that, "Oh, these things

have been extinct for-for 65 million years,"

yet, they still crop up.

And they appear to be prehistoric animals,

dinosaurs, literally, that have survived

right down to today.

Much like the coelacanth

and, uh, alligators, and sharks and turtles,

also have survived from those same prehistoric times.

I believe that ancient, prehistoric monsters

are still living in remote areas of the world,

either in oceans and lakes or jungle areas to today.

NARRATOR: In the Highlands of Scotland,

the legend of the Loch Ness Monster

has long been part of Celtic and Norse folklore.

Recorded accounts of sightings can be traced to the year 565,

to the Irish monk Saint Columba,

a powerful leader who founded monasteries

in both Ireland and Scotland.

In his journals, Columba wrote of an encounter

with people burying a man near the shores

of the now-fabled Loch Ness.

JASON MARTELL: They explained to Father Columba that the man who had died

had been swimming in the lake and was attacked

by the water beast.

Upon hearing this, Father Columba sent

his own follower into the lake.

When the beast came after this man,

Father Columba made the sign of a cross

and commanded the beast not to harm the man.

The beast fled and was never seen harming another man again.

NICK REDFERN: A lot of people don't realize how big Loch Ness is.

It's 23 miles long, a mile wide,

and at its deepest point, it's about 800 feet.

And the water is very, very dark and dense,

and so, it is the prime location where, conceivably,

if they didn't need to surface that often,

they would sort of bypass detection.

When we're confronted with the Loch Ness Monster

or any kind of anomalous creature,

the question really is, where does it come from?

Is it a remnant of the dinosaur age

or is it something which is out of this world?

We know that, for example,

Saint Columba definitely felt that lake was sacred

and that there was something present there

which had a religious connotation,

which is why he went to that place to begin with.

The intriguing thing is that there actually have been

a significant number of UFO sightings

over the loch itself, of strange, brightly lit objects

hovering over the water late at night,

which clearly aren't helicopters or aircraft

or meteorites or anything like that at all.

So, in other words, Loch Ness is a weird and spooky place.

NARRATOR: Could the so-called sea monsters of Loch Ness

possibly be descendants of ancient dinosaurs?

Or might it be of another, perhaps,

extraterrestrial origin?

And if so, what might this say

about other mythical sea beasts,

like the seven-headed Sumerian sea monster, the Leviathan?

YOUNG: The Leviathan is sometimes described as a-a serpent

or a crocodile or a dragon, but it lurks.

It is the gatekeeper to a portal to hell,

and this gateway to hell is apparently deep in the ocean,

and the Leviathan is there, forever lurking.

NARRATOR: In Greek myths, the Hydra was described

as an ancient sea serpent with many heads.

It was said to be a descendant of the Earth goddess, Gaia.

Hercules was sent to kill the Hydra.

But it was terribly difficult.

He would slice off the head

and two heads would form.

He had to ask help from his nephew.

And his nephew had a brilliant idea: bring a torch.

Fire might keep the heads from forming.

So Hercules would bash off one of the heads, and his-his nephew

would essentially cauterize the neck so that another one

wouldn't form, and in this way, the Hydra was finally defeated.

COPPENS: In the case of a Hydra, we have something,

which has several heads, which is once again

a category of a creature

which you would expect not to see.

So we're either confronted here

with something which was genetically engineered,

or which genetically went wrong, but clearly it was

of such importance that it was adhered to in mythology

where it attained a status over the years,

over the centuries up until this moment in time.

NARRATOR: According to Scandinavian legend,

the kraken are legendary sea monsters of gargantuan size

and are said to have roamed the seas

off the coasts of Norway and Iceland.

This fearsome beast was infamous

for its attacks on sailing ships.

YOUNG: The danger was not only being attacked by the kraken.

They would come up to the surface and were enormous,

the size of small islands, so you could, you could

have a collision with a-a kraken

that wasn't even out to attack you.

Another great danger was that if it submerged suddenly,

it formed such a great whirlpool that it could pull a ship under.

NARRATOR: Could such legendary sea monsters have actually existed?

Might they have escaped extinction

in the safety of cold deep waters?

And if so, what other alien life

might be lurking beneath the surface?

When we talk about strange underwater creatures,

it's not just, you know, things we find in mythology.

And in fact, there are some really bizarre

underwater creatures that we know really exist.

Yeah, we now have the technology

to explore the deepest parts of our oceans.

We're finding creatures that are so strange

that even some scientists are calling them

"aliens of the sea."

Right, and what's even more mind-blowing

is that astronauts have found evidence

that some of these aquatic lifeforms

can survive in the vacuum of space.

Now how exciting is that?

(indistinct radio chatter)

NARRATOR: August 19, 2014.

During a routine cleaning,

Russian cosmonauts aboard the International Space Station

discover something incredibly unexpected

covering parts of the windows:

living sea plankton.

According to some mainstream scientists,

the tiny organisms may have been carried to the station

on air currents from the Earth's oceans,

or perhaps launched into space on a contaminated rocket.

But many say these are both highly improbable scenarios.

In the previous episode of cleaning,

which was only about a few weeks prior

to that particular date, there was nothing found.

And the space station was in orbit,

there was no connection with the ground.

So I-I really think that there's absolutely no chance

that these are microorganisms that were

somehow lifted from the Earth.

NARRATOR: Astrobiologist Chandra Wickramasinghe

believes the plankton is of extraterrestrial origin,

and evidence of panspermia--

the idea that life exists

throughout the universe and is spread

by comets and asteroids.

WICKRAMASINGHE: I think what happened was that a small fragment of a comet

that carried microorganisms, uh, including plankton

landed on the window of the, uh, International Space Station.

It's not surprising if one accepts the idea that life

is continuing to arrive at the Earth from space.

PAUL DAVIES: There's always been a problem about life on Earth.

Did it actually start here on Earth

or come here from somewhere else?

Seeing as we don't know how life began, it's up for grabs.

NARRATOR: But whether life originated on Earth

or somewhere else in the universe,

one thing is now certain.

Sea plankton can survive in outer space.

Surviving space is very difficult

actually, primarily because of the-the vacuum of space,

and then the intense radiation.

And so those things, um, in general,

will sort of rip apart tissues.

So the presence of-of plankton

on the space station, um, is remarkable.

NARRATOR: The discovery of plankton on the International Space Station

has led ancient astronaut theorists to ask the question:

If sea life can thrive in the furthest reaches of space,

could the reverse be true as well?

Might there be undiscovered alien life-forms

dwelling in the deepest regions of our oceans?

♪ ♪

Portsmouth, England.

December 21, 1872.

The HMS Challenger sets out

on a three-year scientific expedition

to survey the Earth's oceans

and search for new marine life.

At the time of its departure,

the mainstream scientific viewpoint

is that life cannot exist

more than 1,800 feet beneath the surface of the ocean.

But in March of 1875,

after more than two years at sea,

the crew of the HMS Challenger makes a remarkable discovery.

Using a deep-sea dredge, they uncover

an abundance of life at depths

well beyond 1,800 feet.

Every time they dredged the waters of the ocean,

they kept bringing up weirder and weirder creatures

at deeper and deeper levels.

And it quickly became apparent that the oceans

are teeming with life.

Throughout time, we tend to sort of, uh,

impose our own limitations and our own perspectives

on sort of our view of the universe, right?

And so our idea of the deep ocean was similar to that, too.

We thought that probably nothing else could live

at great depths because we certainly couldn't survive, um,

our bodies couldn't take the pressure.

It's sort of biased, I think, our interpretation

of life in the deep ocean.

WILCOCK: They found over 4,700 different types of new life.

It was a wealth of data so vast that it filled

50 volumes

with 30,000 pages of information.

And was essentially a scientific revolution for its time.

Uh, 220-plus, uh, uh, crew.

Only five scientists.

NARRATOR: In addition to finding new species of marine life,

the Challenger crew also made the first discovery

of what are called "cosmic spherules."

Nickel-iron micrometeorites from outer space.

According to some scientists, these spherules could be capable

of carrying extraterrestrial life.

DAVIES: A lot of those rocks would have carried a microbial cargo.

Cocooned inside of rocks, a microbe could be

quite happy in the harsh conditions of space.

In particular, it would be shielded

from radiation by the depth of rock.

It could probably stay in the dormant phase out in space

for certainly thousands, if not millions of years.

HENRY: When scientists explored these nickel-iron spherules in depth,

they discovered that they contained iron

that was extraterrestrial in origin.

Is it possible that these extraterrestrial substances

were brought here by alien beings and deposited

in the oceans of Earth, along with other forms of life?

NARRATOR: Is it possible that the Challenger

discovered the conveyance

of extraterrestrial life on the seafloor?

Might the deepest parts of the ocean be as alien to us

as the farthest reaches of outer space?

Ancient astronaut theorists believe

the answer is a resounding yes

and point to other strange creatures

that have recently been found in the seemingly inhospitable deep.

♪ ♪

March 2005.

Scientists off the coast of Easter Island

discover the yeti crab, a furry crustacean

that thrives on the seafloor near hydrothermal vents,

fissures that release geothermally heated water.

Using the hair that covers its body, the crab is able

to filter out the toxic minerals the vents excrete.

But as extraordinary as the yeti crab is,

it is just one of many forms of marine life

known to be able to exist in such extreme conditions.

Because of the unique conditions that exist

in the hydrothermal vents, um,

some really interesting and remarkable organisms,

uh, can be found there.

NARRATOR: Another newly discovered organism that puzzles scientists

is the ctenophore, or comb jelly.

When neurobiologist Leonid Moroz sequenced the DNA

of this translucent creature

at the University of Florida in 2007,

he discovered they possessed a complex nervous system

completely different from the entire animal kingdom.

NARRATOR: How comb jellies function continues to baffle scientists,

and their unique properties have led Dr. Moroz

to dub them, quote, "aliens of the sea."

We're still finding incredible creatures in the ocean,

creatures that we never even knew existed.

Could be extraterrestrial life.

It's a big planet, and there are a lot of mysteries still here.

NARRATOR: Could there really be alien life thriving in Earth's oceans?

And if so, might our waters harbor

not only extraterrestrial marine life

but also advanced, intelligent beings?

Perhaps further evidence can be found

in the accounts of mysterious flying objects

rising from the depth of the sea.

You know, we really live in the most exciting of times

because for the first time ever,

we get to see video

that was shot by Navy pilots

showing unidentified craft

flying into and out of the ocean.

Yeah, and that's really exciting footage.

And what we call USOs,

or unidentified submerged objects,

have been reported by the military going back decades.

Right, and there was one case where they detected

a USO at a depth of more than 20,000 feet.

We featured this in a 2013 episode,

"Aliens and Forbidden Islands."

NARRATOR: March 1963.

75 miles off the coast of Puerto Rico.

While training in anti-submarine maneuvers,

the United States Navy's fleet,

led by the USS Wasp aircraft carrier,

detects an unknown sonar target moving in the nearby waters.

For four days, the fleet tracked the unknown object,

recording its speed at more than 150 knots,

or 170 miles per hour.

DOLAN: There is nothing

in any naval inventory anywhere in the world

that can approach anything remotely that speed.

Not then, not now.

Moreover, the object descended to a depth

of something like 27,000 feet.

Again, another impossibility.

The pressures down there are vastly too much.

They would crush any vessel that went down that deep.

At that time, the technology that we had,

the best that we could do underwater

was about 45 knots

and a maximum depth of about 3,000 feet.

For the last 100, 200 years,

there have been many, many accounts

of objects that have been seen underwater.

But exactly what they are, we still do not know.

There's been a tremendous surge of UFO sightings

in Puerto Rico since the early 1990s.

And for many of the Puerto Rican witnesses,

they're absolutely convinced that there's

some sort of massive futuristic installation

deep below Puerto Rico under the ocean bed.

♪ ♪

NARRATOR: Is it possible that aliens have bases here on Earth,

hidden deep underwater

and off the coasts of islands?

Could this explain why so many islands around the world

have stories of unexplained sightings

of objects both overhead

and beneath the sea?

Isolated island would be a perfect location

for, say, extraterrestrial beings

to make their base of operations.

Radar could spot any kind of a craft in orbit very quickly.

However, if you had your base underwater, near an island,

a lot more difficult to be discovered.

Islands are essentially mountains

that are mostly underwater.

What they are, in essence, is energetic upwellings

of the energy of the Earth

pushing higher and higher and higher.

Logically, these types of locations

would be very attractive to visitors from another world,

especially visitors that would be looking for an ideal place

to set up a base or a landing spot

or simply a place where they could draw

some of the Earth's energy.

NARRATOR: The Aleutian Islands.

Just off the Alaskan coast,

this chain of more than 100 small islands

extends west for 1,100 miles,

separating the Bering Sea from the Pacific Ocean.

Here, in the summer of 1945, 14 crewmembers

of the United States Army Transport Delarof

reported seeing what they believed to be a large UFO

emerge from the waters near the island of Adak.

It's reported that a round object

that appeared dark, um, against the setting sun at the time

actually rose up vertically into the air

and then circled the boat two or possibly three times

and was visible for about seven or eight minutes

before it vanished.

DOLAN: Something that comes out of the water,

circles around and then takes off like that,

uh, that's well beyond anything we're supposed to have.

And they're in the middle of the ocean.

That's the important thing to remember here.

There's just nothing, nothing that's supposed to be there,

and yet there's activity being reported there.

NARRATOR: UFO sightings around the Aleutian Islands

continue to this day, but why?

Is it perhaps more than mere coincidence

that the native people known as the Aleuts

believe this is the exact spot

where their ancestors first descended from the skies?

YOUNG: The Aleuts believe they descended

from a creature that had come from the sky.

A dog, actually, had fallen to the island of Umnak

and had had two pups with paws.

But the children that came from those two

were perfect humans.

So, by way of this descent from the heavens

and by way of animal form, we get the Aleutian people.

TSOUKALOS: I find it intriguing that the Aleuts' origin story

has something to do with them having arrived from the sky,

essentially saying that they have been seeded.

So the fact that, to this day, that area of the world

is considered a hot spot for UFOs

is not coincidence.

BARA: There have been rumors that there is

an underground alien or UFO base in the Aleutian Islands.

The question is: Could a base really exist there?

And the answer is yeah.

There's plenty of places-- knolls, atolls, volcanoes--

where, if hollowed out, they would pretty much make

ideal bases for UFOs to use

to come and go as they please and to investigate that area.

NARRATOR: Could there really be a connection

between the high number of UFO sightings

and the Aleuts' origin story?

And if these sacred accounts are rooted in reality,

as ancient astronaut theorists suggest,

might evidence be found underwater?

Perhaps the undeniable proof

lies on the other side of the world,

with the extraordinary discovery of a submerged city.

You know, to me, some of the most exciting discoveries come

when we find that a story we thought was fiction is actually

-based on historical fact. -Right.

One of the best examples of that is the discovery of Dwarka.

Oh, absolutely. And according to the ancient Hindu texts,

that was a site where a cosmic battle

between rival gods happened

who had access to flying machines

and the most incredible of weaponry.

And what's so cool is that archaeologists found

underwater ruins that many believe

are the remnants of exactly that city.

Right. And this shows you that

some of the best evidence for ancient astronaut theory

is actually underwater.

NARRATOR: In 2001, researchers from India's Oceanic Institute

detected anomalies on the bottom of the Gulf of Khambhat

seven miles from shore.

HANCOCK: They had been commissioned

by the Indian government

to do a survey of pollution in the Gulf of Khambhat,

uh, up in the northwest, uh, of India.

And they were not expecting to find

anything except a mess down there.

But suddenly, their side-scan sonar

started returning images of regular structures.

NARRATOR: The images revealed an enormous network of stone buildings,

now shrouded in mud and sand

and covering an area of five square miles.

HANCOCK: What we're looking at in the Gulf of Khambhat

are the remains of cities.

There's actually two of them.

And it turns out that they are positioned

on the side of ancient river channels.

They look like cities that have been submerged

for a very long time

at a time when mainstream archaeology tells us

there were no cities, uh, anywhere in the world.

NARRATOR: Powerful crosscurrents made it nearly impossible

to dive the 170 feet to the bottom.

Still, scientists retrieved dozens of artifacts,

including wood and pottery shards.

CREMO: Some of the dates

on some of the human artifacts that were brought up

extended as far back as 32,000 years.

But the oceanographers concluded that the area

had been covered by water about 9,000 years ago.

So this city had apparently existed

from 32,000

to about 9,000 years ago.

CHILDRESS: Mainstream scholars today claim that

ancient Indian civilization only goes back 4,000 or 5,000 years.

Yet, Hindu scholars themselves say that Hindu civilization

is going back, uh, many tens of thousands,

even hundreds of thousands of years.

NARRATOR: Might the ruins below the Gulf of Khambhat

prove the Hindu scholars right?

Another recent discovery may support their claims.

200 miles to the northwest lies the modern city of Dwarka.

Archaeologists digging deep under the city

found signs of a settlement once inundated by the sea.

Inspired by this clue, they began

searching for more ruins in waters just off the coast.

In only 70 feet of water,

divers discovered sandstone walls,

cobblestone streets,

and evidence of a prosperous seaport.

Scholars declared these ruins to be the remains

of the ancient and legendary city of Dwarka.

Ancient Hindu texts explain that the legendary city

of Dwarka was said to be the dwelling place

of Lord Krishna,

a deity worshipped across many traditions of Hinduism.

Imagine what it would mean for the Christian world

to all of a sudden discover the actual Holy Grail,

the actual Ark of the Covenant.

That would be akin for the Indian population

to discover an actual Dwarka.

This was a very powerful city, which was ruled by Lord Krishna,

and Krishna is still revered until today.

He's one of the highest gods that we have in Hindu culture.

NARRATOR: Hindu texts explain that a king named Salwa

attacked Lord Krishna in the mythical Dwarka.

Ancient astronaut theorists believe

the descriptions of the battle

suggest the use of alien technology and even spacecraft.

CREMO: According to the ancient Sanskrit texts,

with this spacecraft, Salwa attacked the city

raining down energy weapons that resemble lightning.

He destroyed large parts of the city in this way.

When this happened, the king of the city,

the god Krishna, responded by

firing weapons at this spacecraft.

The weapons are described as arrows,

but they're not ordinary arrows.

It said that they roared like thunder when they were launched,

and resembled bolts of lightning or rays of the sun.

In response, it is said that the spacecraft

began to appear in different places simultaneously.

It appeared to be moving in ways that resemble

modern descriptions of UFOs.

So what I find interesting about this account

is there's a spacecraft made of metal

that is firing down weapons on a city on Earth.

NARRATOR: The legend says that Krishna eventually departed Earth,

and the ocean consumed his city of Dwarka.

CREMO: For many people, the description

of fabulous ancient cities

in the Sanskrit writings of India were simply mythology.

But with the discovery of the remains

of a sunken city off the coast of India

in the location of Dwarka, all that has changed.

People are beginning to look at these ancient writings

in a new light and see them not simply as mythology,

but as actual historical records.

NARRATOR: Did India's ancestors witness a war

between extraterrestrial entities?

If the mythical city cited in the Hindu texts

turned out to be real, could there also be evidence

of Krishna and his supernatural powers?

Ancient alien theorists believe a link between

the submerged ruins and extraterrestrials can be found

in another set of texts known as India's Sangam literature.

CREMO: Sangams were assemblies of sages.

It says that the first two Sangams took place

on a sunken landmass called Kumari Kandam.

This area was once above water thousands of years ago,

according to the accounts, but it's now underwater.

It's also interesting that these assemblies of sages

included extraterrestrial beings as well.

And this fits in with evidence discovered

in the Gulf of Cambay

and off the coast of the present city of Dwarka.

NARRATOR: Are the interpretations of India's ancient texts

proof of alien contact in Earth's past?

And are the descriptions of gods

actually descriptions of extraterrestrials?

Perhaps another discovery,

one beneath a mysterious lake,

will yield even more evidence of alien visitors

in the remote past.

NARRATOR: The Andes Mountains, Peru.

Here, at an elevation of 12,500 feet,

lie the dark waters of Lake Titicaca,

the highest navigable body of water in the world.

In August of 2000, an Italian team of divers

and archaeologists launched an underwater investigation

of the legendary lake.

There, submerged under 100 feet of water,

the team uncovered traces of a paved road,

a stone terrace, and a wall nearly a half mile long.

For centuries, local legends have spoken

of a lost underwater city called Wanaku.

Could these ruins provide proof

that such a city did, in fact, exist?

Then, another shocking discovery.

Lying on the lakebed was a large sculptured stone head.

Could this ancient relic offer a clue

to the origins of this incredible archaeological find?

Comparisons were quickly made to similar stonework

found at the nearby ancient city of Tiahuanaco,

just 12 miles south of Lake Titicaca,

a city long thought by ancient astronaut theorists

to have extraterrestrial origins.

CHILDRESS: When the early conquistadors

talked to the local Aymara Indians,

they were told that-that giants

at the, you know, beginning of-of creation

had-had created Tiahuanaco.

The-the Spanish too were amazed by the gigantic blocks of stone.

They felt that the devil had built this building.

HANCOCK: If you look at some of the rock cut on megalithic structures,

uh, in the site of Tiahuanaco,

I personally believe very strongly

that we are looking at an older episode of construction.

And the traces of a forgotten episode in the human story.

NARRATOR: But if the ruins found at the bottom of Lake Titicaca

are from the legendary lost city of Wanaku, what happened to it?

Did it fall prey to a major earthquake

or other natural disaster?

Or was the city, as some ancient astronaut theorists believe,

deliberately flooded?

The more you know about Lake Titicaca,

the stranger it gets.

Archaeologists have problems in really explaining

why there are sunken ruins there

because they're saying that the ruins aren't that old.

They're only 1,500 years old.

And that would mean that Lake Titicaca

has gone through a number of major changes in that period.

And it's possible that, somehow,

the lake itself and the shorelines were manipulated

so that certain areas of Lake Titicaca were flooded

in a sort of artificial way.

There is a type of seahorse that lives in Lake Titicaca,

and seahorses are coming from salt water and oceans,

yet these sea horses are living at nearly 13,000 feet

in the Andes.

NARRATOR: But just how could an ancient people

have artificially created South America's largest lake?

A lake that is 118 miles long and 50 miles wide?

TSOUKALOUS: When you ask the local population

how did all of this come into being,

the Aymara Indians will tell you that all of this

has existed since before the beginning of time.

JORGE LUIS DELGADO MAMANI: In the Aymara legends,

the lake is like the-the place

of genesis, the place where it starts,

all the civilizations in our continent.

These very, very, very old roots.

I mean, we're not talking only about this civilization,

this humanity, we are talking about our seeds,

the roots of the stars.

Some people believe that extraterrestrial built,

but what I believe is that the space brothers help us,

direct us, teach us

because they had experience in many ways.

The legend says that once the space brothers

came to this planet, and they used to live with us,

and they was very important in our lives,

and they used to be very powerful people.

NARRATOR: But is it possible that the lost city of Wanaku

was really built or inhabited

by the ancient ancestors of the indigenous Aymara people?

And if so, could it have been deliberately flooded

to avoid detection from the outside world?

(speaking native language)

(translated): The elders, they used to talk

about the underwater city.

They talk about the lights like the stars

connecting with the lake.

The stars, when they come down to the lake,

there is changes in the temperatures.

MAMANI: There is many legends with lights

coming from the underground of the lake.

It seems they come, they go,

and they return in the different moments.

CHILDRESS: You start to get the idea

that there is some kind of ancient alien underwater base.

And it's possible that some of these sunken ruins are, uh,

somehow part of that base.

NARRATOR: Could the ancient city of Wanaku

really have been built by alien visitors?

And if so, why?

What was their purpose?

Could the discovery of this and other sunken cities

provide the evidence that mankind has been seeking

for centuries?

Evidence that proves we are not alone.

HANCOCK: These mysterious underwater structures

really don't have any context or any background,

but just seem to come from nowhere.

They seem to stand out as being out of place in time,

so there's some question marks, some mystery surrounding them

that might shed new light on human history.

TSOUKALOS: Atlantis, Lake Titicaca, Dwarka.

All those ancient mystery places

always have had a connection to the gods.

The gods who, in the ancient astronaut opinion,

were flesh and blood extraterrestrials.

And in the end,

the ancient astronaut theory will be proven right.

The more we'll discover on our ocean floor,

the more we'll understand that our history

goes way far deeper into our past

than what we've been told because it's right there.

-It's right there, but it's being ignored. -CHILDRESS: Yeah.

There's so much more out there to discover.

I mean, we're-- we've only just scratched the surface.

Yeah, so humanity is more and more being forced

to face that we have this lost history,

this lost ancient past, and it's underwater.

And these stories make it really clear that maybe

we should be concentrating our effort on going

deeper into our oceans

instead of trying to go deeper into space.
