NARRATOR: Mysterious golden orbs

believed to be part of an ancient power plant,

a sacred wooden box

said to facilitate communication with the heavens,

and an elaborately carved ancient tomb

that appears to depict an astronaut.

For more than a decade,

Ancient Alienshas examined evidence

of what could be the remnants of an advanced

and perhaps otherworldly civilization.

Now we're going to explore ten of the most compelling examples

of unexplained technologies ever discovered.

Technologies that just may hold the proof

that Earth has been visited by extraterrestrials.

♪

History and mythology are filled with incredible stories

of human encounters with otherworldly beings,

flying ships and powerful weapons that defy explanation.

For ancient astronaut theorists like me,

these are descriptions of misunderstood technology

that might be extraterrestrial in origin.

And some of the most compelling evidence

that our ancestors witnessed alien technology

can be found in ancient artwork,

like a mysterious carving in Egypt

created thousands of years ago that appears strikingly similar

to an electrical device from the modern world.

At number ten on our countdown

of the top ten unexplained technologies:

the Dendera light bulb.

NARRATOR: Dendera, Egypt.

370 miles south of the Giza Plateau

stands the Hathor Temple.

This 2,000-year-old monument is remarkably well-preserved

and covered with elaborate artwork inside and out.

Among the hundreds of carvings, a curious object can be found

that, according to Egyptologists,

is a representation of a lotus flower.

TSOUKALOS: We have depictions

of this so-called "lotus flower" of, uh, Dendera.

And there are not just a few inside the crypt,

but they're, in fact, also on the outside wall on top.

So, what are we looking at here?

Egyptology suggests that this bulb-like thing

is the depiction of the beautiful aroma

of a lotus flower.

What's often not discussed is the surrounding hieroglyphics,

that say that this has something to do with a bringer of light.

When physicists and electrical engineers

and people look at this, they can readily see

that there appears to be what is a filament

inside this tube that could be interpreted as a glass tube.

It appears to be a blueprint for what we would say is a...

an incandescent light bulb.

DAVID CHILDRESS: It's got a filament inside it

that looks like a snake.

There's a cable coming out of the back.

It's then attached to a small box.

So, here we have what appears to be a depiction

of an electrical device.

This means that the ancient Egyptians,

they knew about electricity, they were actually lighting

many of their temples and tombs with electrical lights.

TSOUKALOS: How did the ancient Egyptians

light the insides of their structures?

Because some structures are deep underground

and filled with hieroglyphics.

The ancient astronaut theory suggests

that perhaps the ancient Egyptians

had access to electricity,

and these lighting materials were given to the Egyptians

by the extraterrestrials.

The idea that ancient Egyptians had light bulbs

almost 2,000 years before Thomas Edison

introduced them in modern times is truly amazing.

And in the 1930s, an archeologist in Iraq

discovered incredible artifacts

that may reveal just where they got the power

to illuminate the ancient world.

Number nine on our countdown

of the top ten unexplained technologies:

the Baghdad Battery.

NARRATOR: Baghdad, Iraq, 1938.

While combing through the collection

at the Baghdad Archeological Museum,

a German archeologist discovers several terra-cotta pots

and copper cylinders dating to around the first century BC.

Remarkably, the pots appear to have been used

for generating electricity

more than 1,800 years before the invention

of modern batteries.

JASON MARTELL: The Baghdad Battery is a very interesting piece

of ancient technology.

They're made up of very simple materials from that region.

Usually a clay pot, copper and an iron rod

surrounded by an asphalt stopper.

NARRATOR: In 2009,

ancient astronaut theorist Jason Martell

showed Giorgio Tsoukalos

just how the so-called Baghdad Batteries work.

MARTELL: This is made out of a clay pot,

clay just found naturally in that region in southern Iraq.

And then they would use a small copper lining,

and an asphalt stopper wrapped around an iron rod.

What we're gonna do is, uh, basically just

fill the clay pot with some weak acidic acid--

orange juice, in this case.

And we'll go ahead and put the copper rod back in there.

Okay.

And these all applied together creates electricity.

You can consistently get about four volts

with something about that large.

So, if we think of a Baghdad Battery

around this size generating four volts,

what if we increased the size to around six feet?

That might generate 20, 30, 50 volts

and have the sufficient power

to actually utilize energy in a way that we do today.

So, it's very possible that the Baghdad Battery

was being utilized in conjunction

with other technological devices.

When we look at this through the ancient astronaut lens,

we see that throughout history,

man has been given technology by the gods.

We have to wonder if Baghdad Batteries

aren't pieces of technology

that were given to man by the extraterrestrials.

Next on our list is a weapon used by the Roman Empire

that was so powerful, it struck terror

throughout the ancient world.

But what's even more intriguing

is that this blazing device

has baffled scientists for over 1,600 years.

Number eight on our countdown: Greek fire.

NARRATOR: Constantinople.

674 AD.

The magnificent capitol of the Roman Empire

is under attack by a fleet of 5,000 Arab ships.

To defend his city, Emperor Constantine IV

unleashes a powerful and mysterious new weapon

that destroys the Arab navy in minutes.

It was the most devasting weapon of the time,

and was called "Greek fire."

CHILDRESS: Greek fire

was a liquid that could be pumped through hoses.

It was like the early flamethrowers of the time,

and when it was ignited as it came out of these hoses,

it would then be directed onto ships

or sometimes onto docks and things like that.

And it would start a tremendous fire

and water could not put it out.

PHIL IMBROGNO: It was said to burn so violently and so hot

that even in the greatest of rainstorms,

the fire would not go out.

And when projected out to sea,

when it sunk into the water

it would still burn on the bottom of the ocean.

HENRY: It gave them enormous technological advantage

in naval and land battles.

Some of the chroniclers would say that

water would, in fact, enhance its ability.

NARRATOR: Perhaps even more astounding

than the incredible power of Greek fire

is the fact that scientists

have not been able to reproduce it

even after 1,600 years.

HENRY: The recipe for this Greek fire had been

very closely guarded as a secret,

and it still represents one of the greatest

enigmas in ancient history.

NARRATOR: What was this mysterious technology?

And, more importantly, where did it come from?

TSOUKALOS: One story goes that Greek fire

was given to the Romans by an angel.

Just change the word "angel" to "extraterrestrial,"

and all of a sudden, the whole story makes sense.

HENRY: You have to ask, why would an angel

offer such a powerful weapon and advantage to the Romans?

Is this an example of extraterrestrial interference

in human affairs?

For ancient astronaut theorists like me,

some of the most intriguing accounts

of unexplained technology

can be found in the pages of the Old Testament.

Like the next item on our list, which we all know as

the vessel used to hold the Ten Commandments.

But it is also written that this mysterious wooden box

could part rivers, destroy armies

and even communicate with otherworldly beings.

At number seven on our countdown

of the top ten unexplained technologies:

the Ark of the Covenant.

♪

NARRATOR: Mount Sinai, Egypt.

According to the book of Exodus in the Hebrew Bible,

it was here that the prophet Moses was instructed by God

to build one of the most important artifacts

in Judeo-Christian tradition:

The Ark of the Covenant.

Moses was given very specific measurements.

It was to be four feet long

and about two feet wide and two feet deep.

The container must be made of acacia wood.

That it must be covered with gold.

The top of the ark was to be surmounted

by two cherubim

that would face each other.

TZADOK: God commands Moses to build

this chest, which the original Ten Commandments

was to be placed.

And the presence of God

would then be seen.

Sounds very simple, but yet there were properties

to the Ark that made it far more

than just a symbolic representation

of something religious.

NARRATOR: Biblical accounts of the Ark portray it

as possessing mysterious powers that aided the Israelites

during their journey to the Promised Land.

Helping to part rivers,

level mountains,

and destroy armies.

COLLINS: The most important thing about trying to understand

how the Ark of the Covenant functioned

is the fact that specific instructions were given by God

to Moses about how

it was to be manufactured.

The exact size.

How it is to be raised off the ground.

How it is to be carried.

And this tells us almost certainly

that we are dealing with technology.

NARRATOR: Is it possible that the baffling powers

ascribed to the Ark provide evidence

that it held highly advanced

and perhaps extraterrestrial technology?

Ancient astronaut theorists say yes,

and suggest clues can be found in rabbinical texts

that describe what the Ark contained.

It is said that the Ark housed--

the actual Hebrew word is "kavod,"

or "glory" of God.

Now this in quote "glory of God"

was not something symbolic, it was something actual,

something tangible,

something energetic.

We know from the biblical story

that when the two sons of the high priest Aaron

came forth to make an offering,

fire entered into the nostrils

and burned them from the inside,

leaving their external forms intact.

We might refer to that as an electrocution.

NARRATOR: According to religious texts,

the Ark of the Covenant was placed inside Solomon's Temple.

And then it simply vanished.

But the extraordinary and unexplained powers

of the Ark continue to interest researchers

and ancient astronaut theorists to this very day.

What are we missing here in the biblical understanding

of this mysterious box?

It was clearly far more than just a religious icon.

There was a technology involved.

And that is what makes the Ark, to this day,

one of the greatest mysteries of our history.

Another ancient description of the Ark of the Covenant

can be found in a sacred Hebrew text

called the Zohar.

And according to one translation,

the Ark contained another mysterious device

that supplied the Israelites

with limitless supplies of food.

Number six on our countdown:

the Manna Machine.

NARRATOR: According to the Hebrew Bible's

book of Exodus, after Moses helped the Israelites

escape across the Red Sea,

he led them into the Sinai Desert,

where they lived for 40 years.

It is said that they survived

by eating a mysterious food

called "manna."

Manna is this magical substance that's

sort of white like cardamom with a taste like honey.

You know, the Bible

tells us, this is what feeds people.

Moses commands the people to take some,

put in a jar, keep it

so that you can always tell the story

of how God fed you.

And that's one of the things that's put,

uh, in the Ark of the Covenant.

That's how special this is.

NARRATOR: While the story of the Israelites receiving

manna from heaven is traditionally understood

as divine intervention,

some researchers have suggested

that it could also be interpreted

as an event involving some kind

of advanced technology.

In 1978, linguistic expert George Sassoon

and electrical engineer Rodney Dale publish

The Manna Machine.

In it, they point to an ancient rabbinical text

called the Zohar that describes manna

coming from a curious device.

TSOUKALOS: George Sassoon and Rodney Dale,

by reading the Zohar,

determined that the translation was wrong.

It was supposed to be

the "transportable one of the tanks."

What does that mean?

So they actually came to the conclusion that

what is described was a type of a machine

that they proposed was driven

with nuclear power

and that that produced

the so-called manna

to the Hebrews wandering out in the desert.

NARRATOR: Is it possible that the Ark of the Covenant

contained a nuclear-powered device?

Ancient astronaut theorists say yes,

and point to clues in the Bible.

In the Bible, we have multiple stories

of people not only dying

when they came in contact with the Ark,

but some only died

a week or two later.

And how did they die?

Because they had boils on their skin

and their hair started to fall out.

Well, that is a sign of radioactive poisoning.

And the only way

that such a result could have been gotten

is if the Ark is

an extraterrestrial device that is radioactive.

We're coming up on the halfway point

in our countdown of the top ten unexplained technologies.

And the next item on our list can be found

across the globe in the form

of mysterious stone statues

and strange figures

painted on canyon walls.

In my opinion, these images aren't just products

of our ancestors' imagination,

but instead are depictions

of space travelers.

Number five on our countdown:

ancient astronauts.

NARRATOR: American archaeologists Matthew Stirling

and Philip Drucker begin an excavation

of an ancient pyramid mound.

Over the next two decades,

they unearth extraordinary statues,

carvings and mosaics

from a previously unknown culture,

the Olmecs.

A civilization that emerged

around 1400 BC.

The discovery is a major archeological find

and produced a sensational piece of evidence

for the ancient astronaut theory.

At the Museum of Natural History in New York City

there is a Olmec figurine.

And if you look at this figurine,

you can tell that this guy is wearing some sort of a suit.

He has some type of controls with tubes on his chest.

On the side, you have six wings coming out of him.

So you have to wonder, what is depicted here?

And in my opinion, it is the smoking gun

of our ancestors having access to aviation technology.

NARRATOR: Could it be that a figurine made more than 2,400 years ago

depicts a person wearing some sort

of advanced flying technology?

Ancient astronaut theorists say yes,

and suggest even more compelling imagery can be found

1,700 miles to north in Utah.

Here, along the walls of Ninemile Canyon,

dozens of ancient cave paintings depict figures

wearing very curious attire.

One of the most important galleries is referred to

as "the Family Panel."

What's interesting about this one is that

it shows these apparently luminous,

humanoid-type beings that appear to have

spacesuits on, a helmet, even antenna.

The Navajos themselves claim

that these petroglyphs

were from people who were before the flood,

before this cataclysm had come to the Earth.

And they maintain that these images were

many thousands of years old.

NARRATOR: Could it be that these figures

really depict beings in spacesuits?

Halfway across the world,

in Northwestern Australia, are dozens of cave paintings

that depict other mysterious beings

who appear to be wearing spacesuits

known as the Wandjina.

TSOUKALOS: The Wandjinas are incredible

because they have these gigantic heads

and these long bodies.

It seems as if they're inside

some sort of a pressurized suit.

Now, the stories behind the Wandjinas goes

that they descended from the sky

and gave knowledge

and jumpstarted civilization in Australia

thousands and thousands of years ago.

Now, this is accepted history in Australia.

So my suggestion is

that the extraterrestrials that came to Earth

thousands and thousands of years ago

didn't just visit Australia,

they visited each and every continent on Earth,

and that is why we have the similar motifs.

When it comes to evidence of unexplained technology

in the distant past,

sometimes the best examples are hiding in plain sight.

Like the next item on our countdown,

which, when you know how to look at it,

reveals what I consider to be

an actual depiction of an ancient astronaut.

Coming in at number four:

King Pakal's Tomb.

NARRATOR: Under a pyramid called the Temple of Inscriptions

at the ruins of Palenque,

archaeologist Alberto Ruz Lhuillier

discovers a mysterious underground stairway

obstructed with large stones.

Over the next three years, Ruz and his team

carefully clear the stairwell consisting of 71 steps.

When the door at the base of the stairwell is finally opened,

they encounter room after room of skeletons and artifacts.

And in the final room,

they find the tomb of King K'inich Janahb Pakal.

The tomb of Pakal is

one of the most amazing pieces

of Maya art that we've ever found.

On the top of the lid is a very elaborate carving

that we believe is a depiction of Pakal

falling into the underworld upon his death.

NARRATOR: Although many historians and archaeologists interpret

the carving on Pakal's lid

as the king's descent into the underworld,

ancient astronaut theorists suggest it depicts

a very different type of journey.

The sarcophagus of Lord Pakal forever will remain

one of the smoking guns of the ancient astronaut theory.

He is in a reclining position.

He has a breathing apparatus attached to his nose,

his hands are manipulating some buttons

and his feet are on pedals.

It looks as if Pakal is lifting off

into space inside some type of a rocket vehicle.

NARRATOR: As far as ancient astronaut theorists are concerned,

the idea that King Pakal's sarcophagus lid

depicts a journey to space is supported by Maya writing

that surrounds the iconic carving.

TSOUKALOS: Those Maya glyphs say

that this is King Pakal's journey to Xibalba.

Xibalbameans "underworld."

Well, archeologists-- about 15 years ago--

revisited the term Xibalba and concluded

that, actually, Xibalbacan also be translated

as "Milky Way."

And all of a sudden, this depiction makes sense,

because what we have here is

a representation of King Pakal

on his journey to the Milky Way.

Located in central Mexico are

the ruins of a mysterious city that is home

to some of the most impressive pyramids ever built.

While the purpose of this complex is still unknown,

archaeologists have found evidence of what appears to be

the makings of an advanced technological device.

Number three on our countdown

of the top ten unexplained technologies:

Teotihuacan.

NARRATOR: Located just 35 miles northeast of Mexico City is

one of the most unique ancient sites on Earth.

Called Teotihuacan, this vast metropolis was

discovered by the Aztecs in the 15th century.

According to Aztec writings,

this city was once home to powerful otherworldly beings.

BARNHART: The name Teotihuacan basically means

"birthplace of the gods."

And the Aztecs believed that the gods themselves,

out of Aztec mythology,

were born there at Teotihuacan.

NARRATOR: The city of Teotihuacan

covers an area of eight square miles,

which is roughly the same size as ancient Rome.

At its heart is a two-mile-long thoroughfare named

the Avenue of the Dead that connects three massive pyramids.

BARNHART: The Pyramid of the Moon sits

at the very beginning of the Avenue of the Dead.

The Pyramid of the Sun sits about midway along the length

of the Avenue of the Dead.

Those are their two big buildings.

Then they built the Temple of Quetzalcoatl.

The temple of Quetzalcoatl is

the most ornate building in all of Teotihuacan.

Its entire face is covered with mosaic stones

with the face of Quetzalcoatl or the plumed serpent...

...with his feathers coming off of his face

and his snake head coming out of the building.

NARRATOR: Most mainstream historians believe this city was once

a religious center.

But ancient astronaut theorists suggest

the city's massive buildings once served

a more profound purpose.

And as evidence, they point to an extraordinary discovery

made beneath the Temple of Quetzalcoatl.

In May 2013,

researchers employed a small robot

called Tlaloc II-TC,

to explore a chamber under the pyramid.

Inside, archeologists found

more than a hundred gold-colored metallic spheres.

COLLINS: These balls are probably

anything between an inch

to about five inches in diameter.

HENRY: Nobody knows the purpose of them,

why they were made, or even who made them,

but the fact that they're there tells us

they are of utmost importance

to what went on at the temple.

NARRATOR: Many archeologists believe

the gold spheres are representations

of celestial bodies observed in the night sky.

But ancient astronaut theorists suggest

they could have served a more profound purpose

and point to another discovery made almost a mile away

at the Pyramid of the Sun in 1906.

COLLINS: At Teotihuacan,

huge mica sheets have been found

beneath a layer of stone flooring

that were 90 feet square

and they were placed directly on top of each other,

and yet you couldn't see them.

So they clearly weren't decorative or aesthetic.

They were clearly functional in their use.

So, what were they doing there?

TSOUKALOS: We use mica today in spacefaring technology.

It's a heat shield

for high, very, very high temperatures.

What is it doing at Teotihuacan?

NARRATOR: Curiously, mica wasn't

the only unusual substance found within the ancient site.

HUGH NEWMAN: They actually found mercury

under some of the pyramids as well.

So, what does this all mean?

Well, mercury is used

in different electrical components

and it conducts electricity.

So, can we suggest

that they were using this

for some advanced technological purpose?

CHILDRESS: Mercury itself is very special.

It's a metal, it's a liquid, it's an electrical conductor.

Mercury can be used for many, many devices,

all of which are high tech.

So you have to wonder

what is going on here at Teotihuacan?

Are these small balls

and the mica and the mercury all working together

to create some kind of electrical device

that's doing something?

That would seem to be the case.

In 2017, Erich von Däniken and I were thrilled

to visit the National History Museum of Transylvania

to examine one of the most exciting artifacts

I've ever seen.

It is a 40,000-year-old aluminum relic

that may provide definitive evidence

of extraterrestrial visitation.

Number two in our countdown

of the top ten unexplained technologies:

The Wedge of Aiud.

NARRATOR: Workers digging a trench along the banks of the Mures River

unearth two giant bones, and with them,

a mysterious metal object

buried 35 feet beneath the surface.

Intrigued by what they found,

the crew takes their discovery to a nearby museum.

GRUIA: The object was ten meters in depth,

associated with some bones,

which they later identified as mammoth bones.

Mammoth were extinct 40,000 years ago,

so considering the association with the mammoth bones,

then the object could be older than 40,000 years ago.

NARRATOR: This strange object, known today as the wedge of Aiud,

continues to baffle archaeologists

because it is made from a mysterious alloy

and appears to have been created

thousands of years before humans

were able to smelt or fabricate metal.

CHILDRESS: The wedge of Aiud weighs about five pounds,

it's about nine inches long,

and it is made out of about 89% aluminum.

And this was very curious to researchers

because the wedge of Aiud had to be a very old artifact.

MICHAEL DENNIN: Humans didn't really start working with aluminum

until well into the 1800s,

but when you look at this wedge and you analyze it,

it really has most of the modern properties

we would associate with aluminum.

NARRATOR: On January 18, 2017,

at the National History Museum of Transylvania,

ancient astronaut theorists

Giorgio Tsoukalos and Erich von Däniken

were offered a rare opportunity to get a firsthand look

at the wedge of Aiud.

Museum curator Ana Gruia

has taken it out of a storage locker

where it has been deliberately hidden

from the public since the early 1970s.

TSOUKALOS: Okay.

This is exciting.

- Okay. - GRUIA: So, this is it.

- TSOUKALOS: Oh, wow. - VON DÄNIKEN: Okay.

TSOUKALOS: Here, this is the... where they took the sample out

and here to make the analysis. - VON DÄNIKEN: Yeah.

And here, you see two pieces that are broken off, sort of.

So, maybe it was attached or something.

But very strange.

So what does the museum have to say about this?

- This is a very strange piece. - It is,

it is a strange piece for us as well.

We don't know what it was used for,

and we acknowledge these uncertainties about its dating

and its composition as well.

VON DÄNIKEN: We have a real mystery here.

But you see this patina over this whole object?

And this creates another problem.

TSOUKALOS: Yes.

Because you cannot fake a patina.

NARRATOR: The patina is a thin coating of various metal compounds

that forms on the surface of the aluminum

during exposure to atmospheric elements.

CHILDRESS: It was covered with aluminum oxide,

which they said would've taken

300 or 400 years to have developed.

And that also baffled scientists.

VON DÄNIKEN: So for what can you use this?

It looks like a hammer or a shovel, but...

Giorgio, what is the word of, uh,

in English... [speaks foreign language]

Oh, an excavator tooth.

Well, it-it looks like this.

- It could have been something like it. - Yeah.

VON DÄNIKEN: But these excavator tooths

are never made out of aluminum.

TSOUKALOS: No, it's too weak.

- VON DÄNIKEN: Aluminum is too soft. - TSOUKALOS: Yeah.

JEFF WILLIAMS: A lot of people dismiss this as a tooth

on an excavation bucket.

If you ever looked at these excavators,

they usually have a row of teeth in the front,

and that's designed to cut through the material.

I think, first of all, they would've noticed

they were missing one.

Second of all, they don't use aluminum,

and they're usually made out of hardened steel.

NARRATOR: If the wedge of Aiud really is over 40,000 years old,

could it be part of an even more advanced technology?

According to ancient astronaut theorists, the answer is yes,

and they suggest it is a fragment

of an extraterrestrial device.

An aeronautical engineer who saw the Aiud wedge,

looked at it and said, "That's a piece of a landing gear

for a vertical take-off and landing aircraft."

Ancient astronaut theorists have also looked

at this wedge and surmised that it's possible

that it's part of a crashed extraterrestrial craft.

TSOUKALOS: Aluminum is often used in spacecraft

because it's a very light material.

So could it be that the object of Aiud

was part of some type of a spacecraft?

Perhaps. It certainly looks

as if it was part of a larger object.

And the question is, well, what object?

And at what time was this?

Perhaps there is an extraterrestrial connection.

There is only one unexplained technology

left on our countdown.

And this one has truly stood the test of time.

We've reached the end of our countdown

of the top ten unexplained technologies,

and this last one is as extraordinary as it is massive.

It's a towering monument of ancient Egypt

built thousands of years ago

that some believe was an energy generator.

Number one on our list:

The Great Pyramid Powerplant.

NARRATOR: On the western bank of the Nile River,

stands the most extraordinary example of ancient engineering,

the Great Pyramid.

It towers above the landscape at roughly 450 feet tall

and consists of over two million stone blocks.

RAMY ROMANY: The Great Pyramid of Giza is a marvel of architecture.

Every block was five tons,

and there is about two million of them to create

a perfect pyramid shape

that is one of the Seven Ancient Wonders of the World.

The most ancient one of them all and-and the only one standing.

Inside the Great Pyramid are a number of fascinating chambers

and corridors, like the Grand Gallery,

this towering stairway

that goes up into the so-called King's Chamber.

NARRATOR: Mainstream scholars theorize that the Great Pyramid

was built as a tomb for the Pharaoh Khufu,

who reigned from 2589 to 2566 BC.

But many experts claim this dating is based on

highly questionable data and suggest the origins

of the three pyramids at Giza are far more profound.

Archaeologists and Egyptologists claim

that they were tombs for the pharaohs,

and yet, no Egyptian pharaoh was ever found

in a pyramid in Egypt.

We have found the mummies of many Egyptian pharaohs,

but they're found in vaults deep underground

at the Valley of the Kings in Luxor,

hundreds of miles away from the pyramids.

CHRISTOPHER DUNN: We're taught in school that the Great Pyramid is a tomb,

but if you look at the complexity of these buildings,

the precision with which they were built,

the features that you see on the inside,

these various shafts and passageways,

for me, it looks like a machine.

NARRATOR: The design of the tunnel system and chamber rooms

within the Great Pyramid have convinced engineering expert

Chris Dunn that the massive structure

was actually an advanced technological device.

I propose that the Egyptians built

the Great Pyramid to be a power plant.

The pyramids were actually geomechanical devices.

In other words, they were attached to the Earth.

They were tuned to vibrate with the frequencies of the Earth,

and they converted the energies of the Earth

into electromagnetic energy.

That energy is broadcast from the pyramid,

it's picked up by the transmitters,

which are the obelisks, placed at key sites,

that are able to be tuned to the specific frequencies

coming from the pyramid.

NARRATOR: As far as ancient astronaut theorists are concerned,

the mysteries of the Great Pyramid of Egypt

require further study.

And perhaps, someday soon, advances in technology

will shed new light on its true purpose.

Archaeology is rooted in interpretation,

just like the ancient astronaut theory.

Something extraordinary happened right here in ancient Egypt,

perhaps under the tutelage of extraterrestrials,

teachers from another star system.

Was the Great Pyramid of Egypt a massive power plant?

The answer may never be known,

but one thing is clear,

from fire that can burn underwater,

to a 40,000-year-old aluminum artifact,

and a biblical relic that could topple stone walls

and feed the masses,

the ancient past is filled with evidence

that highly advanced civilizations

were here on Earth.

And perhaps once we solve the riddle

of these unexplained technologies,

we will finally unlock the secret

of our extraterrestrial past.
