NARRATOR: A mysterious underground temple

that holds gigantic stone coffins.

It's humungous.

You can walk underneath it.

NARRATOR: A 16,000-year-old monument

that appears to float in midair.

NIKKI TSUKAMOTO: This monolith is said to be related to

the heavenly rock ship.

NARRATOR: Ancient engineering feats far ahead of their time.

Someone or some ones had extraordinary knowledge here.

-This is not easy to build. -No.

NARRATOR: On Ancient Aliens, we've traveled to many

mysterious sites that seem to defy explanation.

Now we take a look back at some of the most incredible

structures we've visited all over the world.

Structures, that according to ancient astronaut theorists,

provide undeniable evidence of extraterrestrial contact.

♪ ♪

On Ancient Aliens, we have traveled to some

of the most incredible structures on the planet.

Structures that offer compelling evidence

that our ancestors were visited by extraterrestrials.

And some of the world's most extraordinary examples

can be found in ancient Egypt, like the Great Sphinx,

the Pyramids of Giza and the Luxor Temple.

But Egypt is also home to a site that a lot of people

don't even know about, and one I think is amazing.

The Serapeum of Saqqara.

And when I went to see it in person

with Egyptologist Ramy Romany,

it absolutely blew my mind.

NARRATOR: Saqqara, Egypt.

1850.

While on an expedition to recover

ancient manuscripts for the Louvre Museum

in Paris, French Egyptologist Auguste Mariette

spots a strange object sticking out of the sand.

Intrigued, Mariette has the sand cleared away

and finds large rocks blocking what looks to be

the entrance to an underground chamber.

After using explosives to remove them, he gains entrance

to a tomb complex,

also known as the Serapeum.

In April 2018, ancient astronaut theorist

Giorgio Tsoukalos and Egyptologist

and Cairo native Ramy Romany

visited this mysterious site.

-The Serapeum of Saqqara, Giorgio. -Yes.

Oh, it's magnificent.

The name Serapeum comes from Serapis,

-which is Apis bull and Osiris. -Yes.

-Right. -Combined together in one Greek god.

NARRATOR: Located deep beneath the desert surface,

lies a 790-foot-long passageway.

There, within a series of alcoves

neatly carved out of the limestone rock,

are 24 gigantic stone sarcophagi.

Each sarcophagus measures approximately 13 feet long,

seven and a half feet wide and over ten feet tall.

But just how the ancient Egyptians

managed to transport these massive granite boxes

remains unknown,

as does their intended purpose.

ROMANY: So this is one of the most mysterious

places in all of Egypt, Giorgio.

Look how far all this goes.

The boxes themselves are, what, 70 to 75 tons?

-Mm-hmm. -And then the lids

are estimated to be 20 to 25 tons.

It's one of the most mysterious things about

this place is really how

they managed to bring

these heavy structures all the way down here

when we're breathing heavily just to get to the end.

Can we actually go down to some of these?

Of course we can.

Wow.

You know, I've always read about these.

I've seen pictures, but it's humungous.

You can walk underneath it.

NARRATOR: As far as conventional Egyptologists

and archaeologists are concerned,

the sarcophagi were meant to house

the remains of the sacred Apis bulls.

But as only one of the tombs was found to contain

animal remains and all the others were found empty,

the true nature of the Serapeum is a source of deep contention.

The Apis bull is a representation for god Osiris

and there's something very important to mention.

Ancient Egyptians did not worship animals.

Their concept was the gods sent the animals to be

their messengers, and we have to respect them in that way.

ANDREW COLLINS: It was said that the first ever

Apis bull was created

when a ray of light

came down from heaven itself and struck

this cow

who produced the first Apis bull.

So there is some relationship between

the bull itself and the stars.

The sides, and also here the bottom...

(stammers) the polishing is perfect.

And we can illustrate this by just looking at the angle.

I mean, it's a perfect 90-degree angle.

Check this out. It is absolute perfection.

It's easy to cut limestone.

But to cut basalt is a...

(chuckles) That's a different story.

What do these inscriptions here say?

These inscriptions were extremely important.

You see the doors, specifically, the so-called false doors.

They were the doors that allowed the spirit, the ka and the ba--

the spirit and the soul-- to come out from the mummy.

And then read the hieroglyphic inscriptions.

They wanted to make sure

that these Apis bulls come back to life.

Go to eternity, so they could stay

with Osiris in the sky.

Ancient historians' accounts,

like Herodotus, Strabo,

Eusebius, all of these...

old, old chroniclers speak of a...

a former glory age of Egypt known as the Golden Age.

Which some have suggested dates back as far as 10,500 BC.

So is it possible that what we have right here

may be a remnant of that time?

When it comes to dating, I don't have a response.

I can't tell you for a fact

that this was made 3,000 years ago.

Till today there's a debate on when were these made.

NARRATOR: Egypt's Golden Age was a time when humans

are said to have shared the Earth with the gods.

Gods that, according to the ancient astronaut theory,

were not mythological figures, but extraterrestrial visitors.

And there are those who believe that the figure of the Apis bull

can be found carved into one of the sarcophagi

not because these giant stone coffins held mummified bulls,

but because the Apis bull represented

a connection to the stars.

COLLINS: It is a fact that when most of these

gigantic sarcophagi were opened, nothing was inside them.

But in my opinion...

I think that this acted as some kind

of otherworldly environment

for communication with the cosmos itself.

And that the bulls simply represented

the points of contact with the cosmic beings themselves.

It doesn't make sense that these were built for mummified bulls.

First of all...

they're too big for the bulls.

They're beyond human scale.

In order for a human to get into them,

you would first have to remove the 15- to 20-ton lid

that was placed on top of these boxes.

And then climb up a ladder to get into them.

Is it possible that what we're looking at here is

an extraterrestrial technology that was used

thousands of years ago in ancient Egypt?

What could possibly be the purpose of these boxes?

What function did they serve?

It's an incredible question.

NARRATOR: Is it possible that the massive

sarcophagi contained within the Serapeum of Saqqara

were constructed more than 10,000 years ago

during a period when extraterrestrials

inhabited the Earth?

Ancient astronaut theorists say yes,

and suggest an even more direct ET connection can be found

by exploring the prehistoric megaliths of Japan.

Some of the most incredible structures to have traveled

that have me convinced that we've been visited

by extraterrestrials are the ones that look

just like flying craft.

And when I went to Japan,

I had the honor to see two ancient stone carvings

that are believed to represent flying ships

witnessed by the people who lived there

thousands of years ago.

NARRATOR: Honshu, Japan. April 2017.

Near the modern-day city of Osaka,

Giorgio Tsoukalos meets with fellow ancient astronaut

theorist Takeharu Mikami, to investigate one of the oldest

and holiest sites in the country.

The Ishi-no-Hoden megalith is a giant stone monument

carved out of the bedrock on the mountainside and is believed

by some researchers to date back an astonishing 16,000 years.

(speaking Japanese)

TSOUKALOS: Wow.

It's gigantic.

This is... I had no idea.

I mean, it is massive.

(speaking Japanese)

TSUKAMOTO: The rock itself is said to weigh about 500 tons.

-500 tons? Wow. -Yes.

Okay. That's amazing.

I-I want to... I need to walk around.

Very weird.

I mean, I had no idea how massive this is.

(Mikami speaking Japanese)

So you want to just look down below here.

It looks like it's floating over the water.

TSOUKALOS: It really does.

(Mikami speaking Japanese)

TSUKAMOTO: The name for this rock is... (speaks Japanese)

or "the floating rock from the heavens."

(speaking Japanese)

TSUKAMOTO: 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,

which was called "Ama no Iwafune,"

which is "the heavenly rock ship."

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. -(Tsoukalos laughs)

So do you think that is the reason why it was called

a vehicle made of stone,

because it was so powerful and strong

and virtually indestructible

that the story became, it's a vehicle made of stone?

(speaking Japanese)

You're absolutely right, because the gods were

flying over the land on a giant ship.

It wasn't a plane because it didn't have wings.

It looked like a ship made out of very hard material

that was like a very hard stone.

And they would descend from the heavens

and down onto the land,

and thus, they would travel around the country.

TSOUKALOS: It's absolutely impressive.

To me, the Ishi-no-Hoden megalith was an attempt

by our ancestors to document an extraterrestrial visitation.

And they chose this incredibly hard stone

as a way to represent the color and indestructible

nature of the craft they saw in the sky.

As if this wasn't proof enough of alien contact,

during my trip to Japan, I investigated

another ancient site with an almost identical legend.

Does that say rock ship?

-Masuda rock ship... -Oh, all right.

NARRATOR: Giorgio Tsoukalos and ancient astronaut

theorist Takeharu Mikami

set out to examine Masuda-no-Iwafune,

an 800-ton rock structure

that was carved from a single piece of granite and resembles

no other architecture in Japan.

Check out this-this square grid on the sides.

I mean, this is something that I've seen before in India,

in Mahabalipuram, where they have the same

mythologies of celestial beings.

And they had something very similar

on the side of some of their rocks, as well.

MIKAMI: Mm-hmm.

I can't wait to see the top.

Amazing.

-Oh, man. -Whoa!

Wow. That is...

I mean, I've never seen anything like it.

NARRATOR: While some researchers believe

the Masuda-no-Iwafune megalith is a tomb,

others claim it is meant to depict

the "sky boats" that are described

in ancient Japanese stories.

TSOUKALOS: So the idea is that this was the entrance

to a Buddhist temple-- what do they mean by that, inside?

-I mean, where? -TSUKAMOTO: It would actually

predate Buddhism in Japan.

So it wouldn't have anything to do

-with Buddhist temples. -Right, so...

what is the actual translation

of Masuda-no-Iwafune?

(speaking Japanese)

Masuda is the name of the region,

and Iwafune literally means "stone ship" or "rock ship."

Okay.

(Mikami speaking Japanese)

TSUKAMOTO: Yes, it's... naturally the Iwafune

or "the rock ship"

would have come down from the heavens as a vehicle

for the gods to descend upon Earth.

TSOUKALOS: So I guess with the combination

of the mythologies of celestial beings,

this could be some type of representation

of one of those flying vehicles

that our ancestors perhaps witnessed.

NARRATOR: Could the massive stone monuments both in Asuka Park

and in Honshu have been inspired by encounters

with extraterrestrial craft descending from the sky?

Ancient astronaut theorists say yes, and they believe

that further proof of otherworldly contact

in the distant past can be found halfway around the world,

at a mysterious megalithic site high

in the Andes Mountains.

Many of the incredible structuress

found around the world were built with stone blocks

so massive it seems impossible

that they could have been moved

without advanced technology.

But for me, the site of Puma Punku in Bolivia

is the most astounding of all,

because not only are the stones

megalithic, they're carved with a precision that we would

have a hard time replicating even with modern tools.

Here, 45 miles west of La Paz,

isolated high in the Andes Mountains...

lie the mysterious ancient ruins of Puma Punku.

Spread across a desert plateau at an altitude

of over 12,000 feet,

the megalithic stones found here are

among the largest on the planet,

some measuring up to 26 feet long

and weighing more than 100 tons.

DAVID CHILDRESS: What you have here are massive blocks

scattered like some kid's toy blocks

around the site.

It's like some giant cataclysm

just wiped out this entire area.

Archaeologists are baffled

by what Puma Punku was,

how it looked and what the purpose

of this enormous structure would have been.

One of the amazing things here at Puma Punku

is the precision of the blocks.

You can see with this block that it's really been cut

at very accurate right angles.

Not only do these blocks have precision corners,

but they also have these...

difficult drill holes that are going

right through the rock.

NARRATOR: In January 2011, ancient astronaut theorist

David Childress and author

Brien Foerster gained unprecedented access

to investigate this incredible site.

You know, Brien, this is one of the most

interesting and unusual stones

here at Puma Punku.

It's got these perfect right angles and...

...and then each of these small drill holes

are basically evenly spaced

along this routed groove.

To me it's clear that power tools have been used

on this unusual block of stone here.

Well, exactly. And this surface is as smooth

as a tabletop, like in your kitchen.

There's no wave to it or anything.

This was machined, but who machined it?

It's an astonishing piece of work.

And how anyone could think that primitive human beings

could have done this, you know, it's just crazy.

If anything looks like ancient aliens, it's this stone.

NARRATOR: What did the ancients use to cut these stones so precisely?

Might evidence of advanced technology be found

by further study of the construction

of the Puma Punku stones?

Ancient astronaut theorists say yes,

and point to what they call

H-blocks.

It seems like every one of these H-blocks is exactly the same.

So it's like a prefabrication process

where they needed X-hundred of these

and whatever machinery it is that they had was able with

amazing accuracy to replicate one after another after another.

It seems as though

some kind of factory was set up there

to make these almost exactly the same.

It's almost like a Lego system of interconnecting blocks

and that is unique on this Earth.

CHILDRESS: It's an ingenious way of building a huge wall.

And again, the whole thing is just so incredibly precise.

Doing these kind of inside corners like this.

This-this just can't be done really with,

with copper chisels and... and stone hammers.

The whole thing is... is just so incredibly high-tech.

Even beyond what we would do today.

We don't really know the age of Puma Punku.

Archeologists have come up with wildly different ages.

Starting with early excavations here,

thinking that Puma Punku was up to 20,000 years old.

But the kind of machinery that would need to be used

to articulate and cut these blocks

would be giant diamond saws

with huge blades, powerful routers.

Even possibly we're talking about

plasma cutters and melting of stone.

Something that is only being worked on

today by modern scientists.

NARRATOR: According to the local Aymara people

who have inhabited this region for centuries,

Puma Punku was built in a single day.

And not by humans, but by the sky gods.

They say, "The gods constructed the place

in one night."

This makes sense.

You have an extraterrestrial crew.

They come down to Earth.

So they construct with their tools

just something, which we would call today, a basic camp.

CHILDRESS: When you look at the complexity of Puma Punku,

the huge platforms, the interlocking blocks

made into what they thought were indestructible walls.

What you could have, is the kind of

perfectly made space port,

that extraterrestrials would want.

NARRATOR: Might the ancient city of Puma Punku

really have been built by alien beings,

as ancient astronaut theorists contend?

If so, what happened to these massive,

seemingly indestructible structures?

CHILDRESS: One possibility is that Puma Punku was destroyed

in some artificial blast that literally

blew these buildings apart.

So much of it is not simply broken.

It's shattered to the point where you can find

little tiny pieces of diorite anywhere you look.

And that looks to me like an explosion happened.

At the end of its use, they may have simply

blown it up because they didn't want anyone

to use the technology that they had left behind.

NARRATOR: Precision stonework.

Unparalleled engineering.

And incomprehensible destruction.

Is it possible that Puma Punku

was a point of extraterrestrial contact in the distant past?

Ancient astronaut theorists say yes

and suggest further evidence of alien engineering

can be found on a small island in the Mediterranean...

that is home to extraordinary stone structures.

One of the most incredible structures

that I've ever seen is on the Italian island of Sardinia.

This Mediterranean island has

thousands of mysterious stone towers,

bizarre statues...

and even an ancient pyramid.

But what was most amazing to me was the Well of Santa Cristina.

It features stonework so precise that there is no way

it could have been built without advanced engineering knowledge.

NARRATOR: Oak Island treasure hunter Marty Lagina

has invited Giorgio Tsoukalos to help him explore Sardinia's

mysterious structures and offer his unique perspective.

Local guide Ivana Malu

has taken them to the Well of Santa Cristina,

an ancient structure believed

to have been built sometime around 1800 BC.

(both speaking Italian)

NARRATOR: They are met by archaeo-astronomer

Mauro Peppino Zedda.

-Now, wait a minute, wait a minute, a speta. -Yeah, prego.

These are modern, right? This is reproduction.

-No, no, I mean it. -No, I know! I know. I know.

-This is reproduction. -It's what people say when they are here.

They say, "Oh, Ivana, that's a fake, what is that?"

Can you imagine the well is 3,000 years old?

No, honestly, these are the original stones?

-Really, believe me, 100%. -Wow.

That is built to last for the eternity.

Well, this is spectacular.

NARRATOR: The Well of Santa Cristina demonstrates such incredible

masonry skill that archaeologists struggle

to explain how it was built by so-called primitive people.

Based on his years of research,

Giorgio believes that the stonework may provide

important clues for the theory that a race

of extraterrestrial giants once inhabited the island.

Do you want to touch with your hand

-the sophistication of the wall? -Yes.

Here we go.

Wow.

-Unbelievable. -This is crazy.

TSOUKALOS: Look at this, it is round.

It's a perfect circle.

You can't put a piece of paper, there's no mortar used

to put this stuff together.

-I mean, incredible questo. -It's amazing.

MARTY: Not only is it constructed beautifully,

the foundation is below the water table.

Okay, that's very hard to do. I could tell you from Oak Island,

working in the water is difficult.

This is spectacular.

Santa Cristina Holy Well is one of the most

important sites in Sardinia.

It's part of a Nuragic settlement

that dates back to 1500 BC

with nuraghe towers, menhirs, standing stones,

and everything else there, but the most interesting part

of that is this very sophisticated well.

It's the most precision-carved

stonework I've seen in all of the Mediterranean, really.

It's almost like it was built by the Egyptians

or the Peruvian stone masons. It's so advanced.

It's very fascinating.

The walls around here, any child can do this.

You don't need any sophisticated technology to do this.

But that in there, especially if you think

that there was no written record,

how was this preconceived?

Somebody had to think about it.

Clearly there's two type of builders

that were present there, because you have the well,

which is absolute perfect stone masonry.

And then you have the walls around it

that clearly were created by a later culture,

because it's not sophisticated at all.

It's just a bunch of stones thrown together.

Yet, the well that goes deep into the ground,

it is unlike anything that I've ever seen.

The question is, there was no written language.

How was this planned?

Because if you look at this from above,

it's this keyhole shape, and that to me is fascinating.

I have not seen anything quite like this, okay?

I'm-I'm literally wowed by this.

TSOUKALOS: Clearly someone told the local

people how to place these stones into different areas

because it was a connection to the celestial realm.

So you're surmising the technology

was given to these people?

-The engineering knowledge. -Yeah, okay.

Because this screams

-mathematics. -Yes, it does.

(stammers) I will certainly concur to so-- to this extent,

someone or some ones

had extraordinary knowledge here.

-This is not easy to build. -No.

NARRATOR: Is it possible that someone gave

the ancient Sardinians highly advanced engineering knowledge?

And that that knowledge was passed down

generation by generation for thousands of years?

Ancient astronaut theorists say yes,

and point to another structure

in mainland Italy,

said to have been built under the direction of a god.

Any discussion about incredible structures

has to include cyclopean architecture.

This construction style where massive stone blocks,

known as megaliths, are fit together like puzzle pieces,

can be found all over the ancient world.

And when I visited Italy, I saw one of the most incredible

examples of this extraordinary architecture

at the megalithic walls of Ferentino.

Ancient astronaut theorist Giorgio Tsoukalos

is in the heart of the Italian peninsula,

about 50 miles southeast of Rome.

This area of Italy, known as Latium,

was considered the epicenter of the Roman civilization.

Giorgio is eager to investigate

the ancient city's massive megalithic walls, considered

to be some of the finest constructions in Italy.

-Piacere. Thank you. -Welcome to Italy and to Churcheria.

NARRATOR: For expert insight, he has called

upon local historian Danila Bracaglia.

This is, uh, beautiful-- what can you tell me about this area?

Ferentino, where we are today, is actually known

for these constructions of, uh, the megalithic walls,

founded according to the tradition by god Saturn.

TSOUKALOS: Okay. This is fascinating to me because this

is one of the reasons why I'm here.

What can you tell me about the mythologies

of Saturn in this area here?

So the five cities of Saturn

are all a few kilometers one from another.

And the tradition says, you know,

the towns were founded by Saturn and the Titans.

NARRATOR: In Greek mythology, the Titans were humanlike gods

of enormous stature, who were eventually overthrown

by their children, the Olympians.

Saturn is the Roman name for the Titan Cronus,

who was said to have reigned as an earthly king alongside Janus,

during a "Golden Age" when the gods walked among humans.

Could it be that Saturn and the Titans

actually existed on Earth...

and were responsible

for helping to construct the megalithic

structures found throughout the Mediterranean?

So, Danila, where are we right now?

So, this is one of the entrance gates to the town.

And here, it's actually a perfect point

where you can understand the stratification of the time.

You see the huge blocks

from the pre-Roman time,

then smaller blocks built

in the Roman time, and finally the Middle Age on top.

So basically, you can see the-the megalithic

structure, then the Roman and then Medieval Age.

Exactly. And it's like reading a history book.

So it's, uh, because here it's evident

that people lived here for thousands of years

and-and then they had different technique

of construction, some of them,

like the megalithic, uh, constructions are lost,

so we don't know exactly, uh, when they were built.

TSOUKALOS: Which is, in a strange way, a contradiction

because in ancient times what we're told is that

not much technology existed, so in order to move blocks

like this and put them together,

was an incredible accomplishment,

because it's kind of understandable

how those blocks were moved, and of course the smaller blocks

at the very top, it's not even a question.

So logic would dictate that at first they begin

with the smaller blocks and then, over time,

maybe used bigger blocks, but it's the opposite way.

So it's to me somewhat of a mystery.

At a certain point the technology was lost.

We don't know how they were made for sure.

There is no reference, there's no reference in our

books or, uh, sources about how they were built.

TSOUKALOS: Do you know if all these five cities of Saturn

have the cyclopean walls?

BRACAGLIA: Yes, they have, uh, these walls, megalithics,

or huge stones,

and some of them are better preserved than others.

NARRATOR: Cyclopean walls consist of enormous stone

blocks stacked together without the use of mortar.

TSOUKALOS: I mean, this is incredible.

And this region is not the only

place that has these walls.

For example, we have them also in Greece.

What's even more fascinating is that

we have similar walls on the other side

of the world in Sacsayhuamán, Peru.

You see these, uh, different blocks not only

in Sacsayhuamán, you see them for example

in Abydos. Abydos is in Egypt,

you see a wall, you could think

we are standing in Peru, but Abydos is in Egypt.

You see it on Easter Island.

Which means to me the same teachers.

CHILDRESS: The idea that this unusual construction

using giant blocks of stone that are weighing

up to 200 tons

would be individually developed

in each of these sites is virtually impossible.

So some architect and designer and engineer

developed this technique and now it's

being used literally all over the world.

Who is that designer?

Who is that engineer who came up with this worldwide

megalithic construction technique?

Is it extraterrestrials?

From completely opposite sides of the planet,

we have similar, if not identical, construction styles.

According to the ancient astronaut theory,

Saturn was one of the founding gods

of civilization on Earth.

So the idea that this may have had something to do

with an extraterrestrial visit to me is-is fascinating.

NARRATOR: Could it be that ancient people all around the world

were taught how to build megalithic structures

by extraterrestrials that came down from the sky?

Perhaps further clues can be found

by examining an ancient temple in India

that displays highly sophisticated

engineering knowledge, credited

to a divine architect.

Any list of incredible structures would be incomplete

without featuring the amazing architecture of India.

And of all the astounding places we've visited on Ancient Aliens,

one of the most baffling is the Surang Tila temple.

This unbelievable site was built using ancient construction

techniques that rival anything you'd see today.

Ancient astronaut theorist Giorgio Tsoukalos

is meeting up with archaeologist Dr. Arun Sharma,

to get an up-close look at the Surang Tila temple.

The temple was buried beneath a mound of soil

for hundreds of years until 2006,

when Dr. Sharma headed an excavation of the site.

This is beautiful.

Mm-hmm.

Really?

NARRATOR: Incredibly, the earthquake that hit Sirpur

in the 11th century leveled every modern building

that was standing at the time.

Only the ancient Surang Tila temple survived.

Now, is this considered

Ayurvedic architecture right here?

NARRATOR: Ayurvedic architecture is a construction technique

derived from the ancient science of design

found in Indian texts dating back thousands of years.

That's amazing. Huh.

Okay.

It seems to be almost like some type of glue.

NARRATOR: The glue-like substance is said to form a bond

that is at least 20 times stronger than concrete.

But modern builders have been unwilling

to entertain the notion that such an ancient concoction

could be superior to today's building materials.

Wow, look at this. Beautiful.

The detailed instructions for making this paste can be

found in an ancient Indian text known as the Mayamatam,

a manuscript dedicated to construction techniques.

The information contained within the document

is understood to have been passed down to humans

from Mayasura, the ancient king of the demigods

who was said to oversee various construction projects on Earth.

This right here?

NARRATOR: Curiously, there is a more astounding

earthquake-proof feature at the site

to indicate advanced knowledge was used in its construction.

Located at key points within the Surang Tila temple

are several 80-foot-long shafts designed to form

air pockets that can dissipate the impact of seismic events.

Yes, please.

All right.

Wow.

Oh, wow. This is big. It's a huge book.

And-and this text has been around

for 4,500 years?

In your opinion, where did this knowledge come from?

And you think that this knowledge

originated from the stars?

That's amazing.

NARRATOR: The Sarang Tila temple stands as an incredible testament

to the advanced architectural techniques of our ancestors.

Techniques reportedly passed down to them

from their divine teachers.

And the archaeologist in charge of the dig

is convinced that the knowledge came directly

from extraterrestrial visitors.

Every one of the incredible structures we've traveled to

on Ancient Aliens provides evidence

that our ancestors had contact

with extraterrestrials in the distant past.

And when you put it all together, you have,

in my opinion, undeniable proof

for the ancient astronaut theory.

How else can you explain that thousands of years ago,

people in Japan, Egypt, Italy,

Bolivia, and other locations all around the world were

somehow able to build these massive megalithic structures?

To me, the answer is clear.

They had help from alien visitors.
