A 500-ton monument that appears to hover above the ground.

Giant statues said to have been created with advanced

technology and ornate pillars that depict otherworldly visitors.

Throughout the world, enormous stone monuments have stood for thousands of

years, and many are said to have an otherworldly connection.

Now, ancient Aliens is taking a look back at 10 of the most mysterious monoliths

we've investigated towering standing stones that point

to extraterrestrial intervention on planet Earth.

Across the globe, there are towering stone

monuments that date back thousands of years.

They're called monoliths, and there are more than 50,000 of these mysterious

standing stones that often weigh tens or even hundreds of tons.

But how were they built?

What purpose did they serve?

And why are so many of them associated with stories of otherworldly beings?

We start our countdown with the tallest stone in England,

which also happens to be a hotspot for strange hovering orbs.

At number 10 on our countdown of mysterious monoliths, the Rudston monolith.

Rudston, England.

At the north end of this quaint village in Yorkshire stands a 12th century parish

church that is famous throughout the region, not because of the church itself,

but because of an ancient monolith that towers above the church cemetery.

The Rudston monolith is the tallest standing stone in Britain.

Currently it is 25 feet in height and it weighs 40 tons.

Archaeologists believe the Rudston monolith dates back to at least 2000 BC.

And according to local historians, the giant standing stone has been

associated with strange phenomena in the area for centuries.

We have reports of high strangeness in the region, dating back to the 10th century.

We have accounts of lights in the sky, intelligent light

forms that seem to have a purpose and a will of their own.

So you have to wonder, is the Rudston monolith

there because of all these strange effects?

Or perhaps the Rudston monolith itself is helping create some of these effects.

Could this ancient monolith be a magnet for unusual phenomena?

And if so, how?

According to Ancient Astronaut Theorists, there may be a connection to the fact that

the Rudston monolith stands at a convergence point of what are known as ley lines.

Ley Lines are identified when numerous significant

ancient sites line up in perfectly straight lines.

And researchers have found that along these Ley

Lines there are strong Earth energy currents.

The Rudston monolith apparently is at a junction of three

Ley Lines and there's an energy associated with these.

It's a subtle energy but it's there and it can be amplified by these standing stones.

The ancients knew what they were doing.

They would place them in stones from in

specific spots and it would affect the energy.

But were they working with other beings to do this?

You have to ask these kind of questions because why would they do it?

It seems as if it was the result of some kind of contact with entities,

perhaps even extraterrestrials.

One of the most remarkable things I've ever seen is a giant monument in the

countryside of Japan that is one of the

largest and oldest monoliths anywhere on Earth.

And what's even more intriguing is that ancient lore claims that this massive

stone was carved to resemble a ship that flew through the sky.

Number nine on our countdown, the Ishi no Hõden monument.

Takasago, Japan.

This small city just west of Osaka is home to one of

the most extraordinary wonders of the ancient world.

A colossal monolith called Ishi no Hõden or the floating stone.

Standing 18 feet tall, 21 feet wide, and almost 24 feet thick, the Ishi no Hõden

is estimated to weigh 500 tons, making it one of the largest monoliths on Earth.

In 2017, Giorgio Tsoukalos traveled to the Yoshiko shrine

to investigate the colossal monolith.

He is joined by fellow ancient astronaut theorist Takeharu Mikami.

Wow, it's gigantic.

I need to walk around.

I had no idea how massive this is.

Archaeologists have been unable to date its construction, but according to

Japanese mythology, the Ishi no Hõden could be more than 16,000 years old.

The massive monument is made of volcanic tuff and

was carved in place out of the surrounding bedrock.

Its name, floating stone, comes from a unique

feature that can be seen under the huge rock.

So, do you want to just look down below here?

It looks like it's floating over the water.

It really does.

But what interests Georgiou the most is what the monolith is said to represent.

So this monolith is said to be related to one of the first Gods that descended from

the heavens to Japan, and he is said to have traveled

over the country on a sky ship made out of a giant rock.

So what you're telling me is that there is an ancient Japanese legend that speaks of

a deity flying around in the sky with a gigantic vehicle made of stone?

Absolutely.

The fact that they used this water mirror underneath the stone to show as if it is

hovering and floating in the air, to me, is one of the smoking guns by our

ancestors to show that these things were actually in the sky.

Our next mysterious monoliths are an instantly recognizable symbol of ancient Egypt.

They are the most perfectly carved stones in

existence, and some of the largest as well.

But what most people don't know is that these towering

pillars were seen as points of contact with the Gods.

At number eight on our list, obelisks.

Egypt.

Thousands of years ago, the people here produced some of the most enduring

monuments on Earth, including massive pyramids, elaborate temples, and some of

the largest monoliths ever created, called obelisks.

The Egyptian obelisk is one of the most unique

pieces of architecture in ancient Egypt.

Every obelisk you look at, it is geometrically perfect.

They were always made of granite, and they were foursided, and towered

upwards, and eventually ended in this perfect pyramid.

Most obelisks are between 70 and 100 feet tall, and they can weigh over 100 tons.

But what compelled the Egyptians to carve such perfect monoliths in the first place?

Perhaps the answer can be found by taking a closer

look at the unique properties of this stone.

Obelisks are a piece of crystalline granite,

and within the granite is quartz crystal.

So obelisks themselves are, in a sense, a crystal tower.

It's an antenna, and any antenna can receive

a broadcast, and it can give a broadcast.

Could it be that 4,000-year-old obelisks were antennas?

Ancient astronaut theorists suggest the writings of

the ancient Egyptians themselves support this idea.

According to hieroglyphic records known as the Edfu texts, a 130-foot-tall obelisk

once stood at Abu Ghorab in Memphis, where the people could commune with the Gods.

Abu Ghorab was known as the place of the Gods.

And what's so interesting is that most mainstream Egyptologists are actually

saying that we know it as a place where the ancients connected with divine energies.

The ancient astronaut theory is suggesting that ancient

Egyptians were in direct contact with those extraterrestrials.

I find it fascinating that many of the monoliths we've investigated on ancient

Aliens are covered in symbols or writing that point to another worldly connection.

One of the most compelling examples of this can

be found in an ancient Mayan city in Honduras.

At number seven on our list of the top 10 mysterious monoliths, the Stelae of Copan.

Copan, Honduras.

This ancient site, located deep in the jungle, served as one of the most

important city centers of the Maya civilization.

At the peak of its power in the 9th century AD, the kingdom of Copan had a

population of at least 20,000 people and covered an area of over 100 square miles.

Copan is a classic Maya city that sits at the far eastern edge of the Maya world.

Most of the Maya world is built out of limestone and

a lot of those limestone monuments have now melted.

But Copan's sculpture, because it's in volcanic tuft, is beautiful.

It's deep relief and still very visible.

Among the most remarkable carvings discovered at Copan

are the more than 80 monolithic statues known as Stelae.

The most fantastic part of Copan is the carved

monuments which are carved in the round.

They're not what we call plano convex, like

a slab with a, you know, low relief carving.

These are carved in a sort of Michelangelo way

in the round and they're absolutely fantastic.

Copan is full of big Stelae that stand 10-12 feet above the surface of the Plaza.

They are single monolithic stones carved with

all sorts of hieroglyphs and images of rulers.

The most well-known of Copan Stelae were built during the 43-year reign of the

ruler Wachaklahun Ubukaweel, better known by the nickname Eighteen Rabbit.

On one of the Stelae of Copan, Eighteen Rabbit portrayed himself as the

foremost patron God of Copan, the all-encompassing God, Chanteau, and on the

Stelae he basically gives a dissertation on the cosmos.

For all intents and purposes, Eighteen Rabbit is depicted like modern-day astronauts.

You see tubes, you see weird boxes, you see weird canisters and tanks,

you see boots.

It looks more technological in origin.

Does the monolithic statue of Eighteen Rabbit commemorate

the Maya's interactions with extraterrestrials?

As far as Ancient Astronaut Theorists are concerned, the answer is a resounding yes.

The Maya, in their own words, tell us that the founders of the Mayan civilization

were in fact star beings that had come down in the distant past.

It would seem that these Gods of the ancient Maya were real physical beings,

and they were interacting with the Mayans, giving them knowledge, and were really

instrumental in creating this advanced culture in Central America.

2500 miles south of Copan, high in the Andes Mountains of Bolivia, is a massive

doorway carved from a single piece of stone.

It stands near one of the most extraordinary ancient sites on the planet

called Puma Punku, and carved into the monolithic doorway are strange winged

beings that, from the perspective of an Ancient Astronaut Theorist like myself,

clearly represent extraterrestrial visitors.

Number six on our countdown, the Gate of the Sun.

Bolivia, 1549.

While searching for the southern capital of the Inka Empire, Spanish Conquistador

Pedro Sieza de Leon comes upon a mysterious site, a vast, abandoned city

near the shore of Lake Titicaca that the locals call Tiwanaku.

The ruined city contains temples, huge Megalithic

structures, and vast ceremonial buildings.

Tiwanaku was huge.

It spanned for miles and miles and had a

population of perhaps as many as 20,000 people.

Among Tiwanaku's most impressive ruins is a terrace mound called Puma Punku,

containing dozens of stone blocks, cut with extraordinary precision,

and at the opposite end of the complex, at the entrance to a large, sunken Plaza,

stands a giant carved doorway called the Gate of the Sun.

Cut and shaped from a single andesite stone, the massive monolith is 10 feet

tall, 13 feet wide, and weighs more than 10 tons.

The Gate of the Sun is the icon of Tiwanaku, if not for all of South America,

and it is an amazing sculpture that's carved with some very elaborate iconography.

It features the Inca God Viracocha, who's the God of creation, who's portrayed

as a sort of a humanoid figure with rays coming off his head.

Viracocha was the primary deity of the Andes, going back many thousands of years.

It was thought to be the founder of all the ancient sites we see in Peru and

Bolivia today, including Tiwanaku, Cusco, Saxe Wuman, Machu Picchu,

and many others.

When European explorers rediscovered the monolithic doorway in the 19th century,

it was lined flat on the ground and broken into two pieces.

Today, it stands where it was found.

But many archaeologists believe this is not its original location.

It's standing there and we all know it's not where it used to be.

It's architecture and the way the stone is cut in these right angles.

The only other place in all of Tiwanaku that we see that is Puma Punku.

Puma Punku is one of the most enigmatic places on planet Earth.

Some of the stone blocks are over a hundred

metric tons at an altitude of almost 13,000 feet.

And the legend is that this place was built by the so-called Gods.

Is it possible that Puma Punku was built by otherworldly beings, as legend suggests?

Ancient Astronaut Theorists say yes and believe further clues can be found by

taking a closer look at the depiction of Viracocha carved on

the gate of the sun and the strange beings that surround him.

Viracocha is flanked with 48 winged beings.

Now why would these beings have wings attached to them?

Well, because our ancestors tried to signify flight.

What I think is depicted on the gate of the sun is a type of a celestial Pantheon,

suggesting that whoever came and imparted knowledge at Tiwanaku and Puma Punku were

beings that had a celestial connection, meaning they came from the sky.

We're nearly halfway through our countdown of the top 10 mysterious monoliths.

And while the monuments we have investigated so far are tall standing stones,

archaeologists have also discovered monoliths that are perfectly round.

At number five, the stone spheres.

Zavidovići, Bosnia, 2016.

Archaeologist Dr. Sam Osmanage and a small team of researchers are hiking along the

Bosna River when they spot what appears to be an

enormous stone sphere hidden in the forest floor.

We started clearing it, realizing that it was huge, monumental in size.

Once we cleared almost all of it, we've done the measurements.

It is more than three meters in diameter.

The specific weight, 37 tons.

So this was the largest stone sphere discovery in the world.

While the giant stone sphere in Bosnia is impressive, it is not unique.

From Kansas to Kazakhstan, we find these stone spheres.

Some of them are massive.

And the key thing that links all of them is this incredible mystery about how were

they created, why were they created, and ultimately, what is their purpose?

What compelled ancient people to create monoliths in the shape of spheres?

Ancient Astronaut Theorists suggest clues can be found by

examining a discovery made deep in the jungles of Central America.

In the 1930s, workers in Costa Rica found hundreds of giant stone spheres.

About 300 have been discovered so far.

Some of them are huge, between eight and nine feet tall and wide.

They look like they're created in a machine.

Archeologists believe that the Diki civilization carved the spheres with

simple stone tools, and they are thought to be at least a thousand years old.

But just what purpose did they serve?

We do not know the original location of most of these spheres.

You just start to wonder, what if we could go back in time and

see the exact location of all the spheres, what would they show?

Would they show a pattern?

Would they show a constellation map?

Would they be like the Nazca lines, like a pattern that you could only see from above?

How and why Costa Rica's monolithic spheres were created has been lost to history.

But ancient astronaut theorists suggest that local

legends reveal a connection to other worldly beings.

One very interesting explanation for the Costa Rica spheres is that they were

created by Tara, the God of thunder, who used some sort of a blow pipe to

shoot these spheres out of the pipe in order to push back hurricanes.

Ancient astronaut theory says that within legends like this there's often a kernel

of truth, and so you have to wonder, is this a calling card from some

extraterrestrial entity, a sky God, Tara, with some sort of message?

The fact that our ancestors created such perfectly round spheres is truly

fascinating, and even more intriguing is a collection of huge monoliths that are not

only round, but are also carved with mysterious human features.

At number four on our countdown of the top

10 mysterious monoliths, the colossal heads.

Tres Zapotes, Mexico.

1938.

Smithsonian archaeologist Matthew Sterling makes a remarkable find.

He discovers a colossal stone head buried in the ground.

Over the next few years, 16 more heads are discovered, partially buried at four

locations in Mexico, including 10 in San Lorenzo and four in La Venta.

These monolithic statues are carved from basalt and vary in height from nearly five

feet to over 11 feet tall, the largest weighing approximately 50 tons.

Archaeologists believe the stone heads are some

3,000 years old and were created by the Olmecs.

The Olmecs, they're often called the mother culture of Mesoamerica.

They are the first complex culture of any size

and significance in that part of the world.

For decades, archaeologists assumed the colossal stone heads

were carved to honor important figures in Olmec society.

But just who they depict has been the source of debate among researchers.

The controversy is that many of the beautifully

carved statues and Stelae seem to show African men.

They appear to be not native to the new world,

but are in any of the sub-Saharan Africa.

This is not scientific physical anthropology, but just

the appearance of these things is pretty suggestive.

Is it possible that the Olmec stone heads are a record of ancient visitors who

traveled thousands of miles to central Mexico?

According to ancient astronaut theorists, these

monoliths might serve a more profound purpose.

And as evidence, they point to research done by a team of scientists at Harvard,

Yale, and MIT that revealed the colossal

stone heads have unusual magnetic properties.

The Olmec were craftsmen at finding these magnetic fields in basalt rock.

And they would actually hunt down large

stones, take it back, and carve it into heads.

And they were so precise with knowing where the magnetic

fields were that they actually carved around these anomalies.

When we look at how the ancients were selecting certain stones that were

magnetic or had certain energies, we wonder how they

could know about all of the properties of these stones.

Are they getting this information from extraterrestrials?

Could it be that the ancient people of Mesoamerica received instructions to

sculpt these giant basalt heads from extraterrestrial visitors?

But if so, why?

According to ancient astronaut theorists,

they may have been designed for data storage.

Certain stones like basalt hold a magnetic field and can be magnetized.

A basalt stone could actually act like a hard disk for a computer.

When we look at how we store information today, we have to understand that an

extraterrestrial civilization might approach this from a different angle.

So is it possible that extraterrestrials have embedded

ancient sacred knowledge in statues or in monuments?

And if we were able to extract this information, there could be a wealth of

information ready waiting at our fingertips.

Running through the countryside of northwestern France are thousands of

standing stones that are aligned in perfectly straight rows.

And while their purpose is unknown, some believe

they were part of a long-lost technology.

At number three on our countdown of the top 10 mysterious monoliths, the Carnac stones.

On the northwest coast of France lies the most famous and mysterious collection of

ancient standing stones found anywhere in the world.

Stretching across an astonishing two miles of rolling countryside, more than 3,000

giant monoliths are organized in neat formations.

They are collectively known as the Carnac stones.

The megaliths of Carnac in Brittany are just amazing.

Some of them stand about 30 or 40 feet tall.

There's multiple avenues of stones going right over hills.

No one's really worked out exactly what their purpose is.

These are arranged in four huge alignments.

Some of them are in parallel lines, some of them are fan-like.

Archaeologists believe the monoliths were erected more than 6,000 years ago,

making them older than the Great Pyramid of

Egypt and the stone circles of Great Britain.

But just why the stones are in such precise alignments remains a mystery.

One of the most interesting is the alignment of Menac.

When viewed from above, we can see these 11 almost

perfect parallel lines that stretch out for almost a mile.

So the Menac alignment is so pristine and created with such perfection.

We can't even imagine how it would have been done in ancient times.

We have to wonder what these lines were for.

I think in Carnac our ancestors did not know what they were creating.

The entire region has over 4,000 stones.

Somebody told our ancestors why to move it there and above all how to move it there.

Carnac, at some point, was an extraterrestrial hotspot.

Is it possible that the position of the Carnac

stones was directed by extraterrestrial visitors?

As Ancient Astronaut Theorists suggest, perhaps clues can be found by examining a

discovery that may point to these mysterious

monoliths having served an energetic purpose.

In 1992, a French engineer named Pierre Merot did a study of the Carnac stones and

what he found was that the stones were aligned

and placed over areas that had quartz fissures.

The standing stones themselves are also made of quartz.

And if there are quartz crystals within the stone, those

crystals can actually be vibrating and storing energy.

Today, quartz is used in watches, speakers, and computer storage systems.

Is it possible that the Carnac stones, with their high quartz content and

strategic placement, had some kind of technological function?

It's really interesting that these stones are standing in just the right locations

where you could create a phenomena like this.

You can store and create electromagnetic energy in these types of stones.

Somebody understood something about the quartz in the ground, the standing stones,

and the fault lines.

It's too big of a coincidence for them not to have understood that.

Were the Carnac stones created to be part of an electrical grid, one that was

designed by extraterrestrial visitors to tap

into the natural energy produced by the Earth?

If so, what exactly were they using the energy for?

Energy can be amplified by these standing stones and it can be emitted as well.

Much like we use antennas and towers, radio towers and things like that,

we have to wonder does it have to do with extraterrestrials and spacecraft?

What if somebody came here who has been around longer than us and has figured out

how to harness the energy of the planet through use of standing stones?

The stone rows in Carnac Brittany to me are a calling card.

It's a message that somebody was here in the past and they were our teachers.

Thousands of miles off the coast of South America is a tiny island in the South

Pacific where hundreds of massive stone statues stand guard on the shoreline.

Archaeologists believe that these sentinels could be more than 800 years old.

But just whom they depict and how they were moved into place is an intriguing mystery.

Number two on our countdown, the Moai of Easter Island.

More than 2,000 miles off the coast of Chile, a rocky island rises from the ocean.

Called Rapa Nui by the locals, it is best known as Easter Island.

Due to the fact that Dutch explorer Jacob Roggeveen

discovered the island on Easter Sunday, 1722.

As recorded in the ship's log, Roggeveen and his crew

were astonished by what they saw along the shore.

We noticed certain remarkably tall stone figures.

These stone figures caused us to be filled with wonder, for

we could not understand how it was possible to erect them.

Some of these statues were a good 30 feet in height and broad in proportion.

Known as the Moai, more than 1,000 of these monolithic

statues are scattered across Easter Island's grassy cliffs.

The statues on Easter Island, which we call Moai, are

one of the great archaeological wonders of the world.

They are unique.

And we believe that overall they carved something

like a thousand of these Moai over some centuries.

You don't realize that they're really buried right up to their chest and that

these statues are two or three times as large as

we can see because most of them is below ground.

Many of the statues are oftentimes sort of sideways looking up.

Most Moai stand between 13 to 20 feet tall, but some reach as much as 30 feet high.

According to archaeologists, the native Polynesian inhabitants of Easter Island

constructed the Moai between the 12th and 17th centuries AD.

Why did these people go to such great effort to build these giant statues?

No one else in Polynesia was doing that.

When you talk to the people of Easter Island today, the Rapa Nui people,

they say that they were doing them to honor

certain important ancestral ariqui or rulers.

These Moais are images of great ancestors.

As far as Ancient Astronaut Theorists are concerned, these monolithic figures aren't

just depictions of ancient rulers, but visitors from another world.

The thing about these Moai is that they have these very strange faces,

very elongated.

They don't look quite human.

They're humanoid, but they're somehow different than ordinary humans.

They look almost Alien in appearance.

And you have to wonder, what do they ultimately represent?

You cannot exclude that they are representation of celestial ancestors.

We have all these status and the faces of the

status do not look like the Easter Islanders.

The status they created, they look like robots with long, narrow noses,

with narrow lips.

They have nothing which compares the Easter Island people.

Is it possible that the Moai depict extraterrestrial

beings who were once present on Easter Island?

Ancient Astronaut Theorists say yes, and suggest these

visitors also helped in the erection of the giant statues.

According to the local Rapa Nui people, their ancestors possessed a type of divine

energy called mana that allowed them to levitate the Moai.

The king was given the gift of mana from the great creator God Maki Maki.

Mana is a magical energy and it seemed to be capable of extraordinary feats.

And the king used the power of mana to command that the great stone statues walk.

In my opinion, mana was some type of extraterrestrial

technology that allowed these stones to be levitated into place.

We're heading towards the number one entry on our countdown of the most mysterious

monoliths, and some consider these standing stones to be the most enigmatic on Earth.

We've reached number one on our countdown of the top 10 mysterious monoliths,

and this collection of massive standing stones

has baffled historians for hundreds of years.

It's a neolithic monument that some believe has a profound connection to the cosmos.

At number one, Stonehenge.

Wiltshire, England.

The neolithic monument known as Stonehenge has dominated

the landscape here for no less than five thousand years.

This iconic stone circle consists of an outer ring of 30

monoliths topped by connecting horizontal lintel stones.

And within this ring are five even larger stone arches.

Some of the stones Stonehenge weigh between 50 and 70 tons.

Some of the stones are even heavier.

So how could you have moved these into place?

If we go to the traditions of ancient England about how the stones were moved,

we know that there are stories of Merlin somehow

levitating the stones all the way from Ireland.

Merlin, the powerful wizard of British mythology?

According to some researchers, Merlin was not

only real, but a figure who was not of this world.

The great 20th century French philosopher and historian Jean Markale wrote over 40

books on the Celtic traditions and was adamant that

Merlin was an incredibly powerful otherworldly being.

And in a number of legends, Merlin brought the understanding of how to utilize these

stones in some extraordinary way in terms of technology, communications, energy.

Could the legend of Merlin really be the story of an ancient Alien visitor,

one who helped to build the mysterious Stonehenge

monument for some kind of technological purpose?

The point is that the standing stone formations that we find all around the

world are pieces of the puzzle of the ancient astronaut theory that long ago we

received visits from outer space and we were visited

by none other than our first teachers on planet Earth.

But if Stonehenge really was of extraterrestrial design, the question remains.

What purpose might this Megalithic stone circle have served?

According to some ancient astronaut theorists, the

site might have been a portal to another world.

Archaeologists now are speculating that the bluestones that are part of the

Stonehenge complex, they are a type of black blue

dollarite that has very bright nodes of quartz in them.

So you have electrical qualities when the quartz is kind of crushed and then you

have magnetic qualities as well within the same stone.

So this could have been used to manipulate Earth energy currents.

You have to wonder if it's a way to create a special portal area.

It's got a special energy perhaps being manipulated

and created by these Megalithic structures.

What is it that compelled ancient people to

construct enormous standing stones across the globe?

It's a question that Ancient Astronaut Theorists

believe has an extraterrestrial answer.

And whether they were used as energy sources, or as signals to be seen from

above, or even as points of contact with otherworldly visitors, the more we learn

about the ancient monoliths, the closer we will

come to revealing the truth about our Alien origins.
