Giorgio a. Tsoukalos: An island of giant statues.
A vast plateau covered in enormous geoglyphs.
A megalithic settlement
That dates back more than 12,000 years.
On ancient aliens,
We've trekked across deserts,
Hacked through jungles,
Flown to remote islands,
And climbed rugged mountains
In order to investigate extraordinary sites
That seem to defy any conventional explanation.
We're going to look back at what I consider
To be the top ten ancient sites we've visited.
And you can decide for yourself,
Do these places hold the proof that earth has been visited
By extraterrestrials?
♪ ♪
When I think of all the mysterious sites
We've investigated on ancient aliens,
It's really tough to narrow them down to the top ten
And even tougher to rank them.
Each of these sites offers compelling evidence
That extraterrestrials visited our ancestors.
And at one particular site in peru,
That evidence is imprinted right on the vast desert floor.
And what makes it even more incredible
Is that you can only see it from high above the earth.
At number ten on my list of top ten mysterious sites,
The nazca lines.
♪ ♪
Narrator: Southern peru. 1927.
While hiking in the foothills of the arid nazca desert,
Archaeologist toribio mejía xesspe discovers
What appears to be a large network of ancient roads
Carved into the earth.
Years later, as airplane travel to the region
Becomes more frequent,
Aerial flyovers reveal nearly 100 other designs
In the nearby landscape.
Nick redfern: The nazca lines consist
Of these massive drawings
Or carvings, if you like, on the ground.
Everything from geometric symbols, lines
To animals, even fish, birds.
But the intriguing thing about them is, you know,
That, number one, they're massive.
And they can really only be seen properly from the sky.
Narrator: According to mainstream archaeologists,
These mysterious earth drawings were created by the nazca,
An ancient people that flourished in the region
Between the first century and eighth century ad.
But what was their purpose?
Erich von daniken: Archaeology has still no answer.
In my opinion,
It has something to do with the extraterrestrials.
Our ancestor made these gigantic signs in the ground
Because they want to signalize to the beings up there,
"we are here. Come down here."
If you leave nazca and travel due west
Some 2,400 miles out into the pacific ocean,
You'll eventually reach one
Of the most remote islands on earth.
It was discovered by dutch explorer jacob roggeveen
On easter Sunday, 1722,
And he was amazed by the gigantic stone statues
He found all over the island.
They've become one of archaeology's greatest riddles.
Mysterious site number nine, easter island.
♪ ♪
Narrator: April 5, 1722.
Dutch explorer jacob roggeveen and his crew
Are 2,400 miles off the coast of chile
When they spot a small landmass completely isolated
In the pacific ocean.
As they draw closer,
They are surprised to find
That the remote island is inhabited.
But even more unexpected
Are the giant stone figures
Staring out at them from the shore.
Paul bahn: The statues on easter island, which we call moai,
Are one of the great archaeological wonders
Of the world.
We know they carved
Something like a thousand of them
Over a period of probably roughly about 500 years,
Weighing tens of tons.
No other culture in the world has ever done this,
Certainly not on this scale.
In many ways, we still don't know exactly how they did it.
Narrator: The moai were found to have been carved
From the volcanic bedrock at the center of the island.
But exactly how the native people managed to move
Such enormous statues out to easter island's shoreline,
In some cases more than 11 miles from the quarry,
Has been the subject of endless debate.
There have been many theories over the years
As to how they were moved.
The first theory is thought
That they must have been dragged horizontally
On sledges or rollers or something of that kind.
It was tried again recently for a tv film,
And, again, they moved it a few meters,
But it really doesn't prove anything.
You're talking about several hundred statues.
And it would depend on the size and weight of the statue,
The number of people you had available to help,
The distance you were going to go,
The kind of terrain.
So, basically, we don't really know.
According with the oral tradition and the legends...
Tsoukalos: So one has to wonder if mana was some type
Of extraterrestrial technology
That allowed these stones
To be levitated into place.
Some have suggested that sound technology was used
In order to move some of these rocks.
Because scientists have proposed that levitation technology
Can be achieved with one thing,
Sound frequencies.
This mana is an energy that no one understands today.
Is it some kind of extraterrestrial energy?
We just don't know.
You know, what's really curious is that so many
Of the world's most massive megaliths are found on islands,
Where, in ancient times,
Resources and manpower were extremely limited.
And on one island nation in the middle of the mediterranean sea,
You'll find some of the oldest
And most enormous structures anywhere on earth.
Number eight in our countdown of mysterious sites,
The islands of malta.
♪ ♪
Narrator: The maltese islands lie in the center of the mediterranean sea,
Just south of Italy.
Scholars believe the first inhabitants migrated here
From the nearby island of sicily in 5200 bc.
Today, stone structures on two of the islands,
Malta and gozo, are considered by archaeologists
To be among the greatest achievements
By ancient builders anywhere in the world.
There are engineering features in these temples
That are just astonishing.
We're talking about walls enclosing space,
Paved walkways.
They were ceilinged at one time.
Definitely much more complex than anything else
That was appearing on earth for a very long time.
♪ ♪
In 2014, giorgio tsoukalos traveled to malta
To get an up close look
At its incredible megalithic structures.
At the temple of hagar qim,
He met with dr. Anthony bonanno,
A professor of archaeology and classical literature.
-What does "hagar qim" actually mean? -So-- oh, well,
"stones of worship" or "standing stones."
-Like this one. -There you are, yes.
-That's right. -Check this out. This is huge.
-Wow. -Yes, uh, three meters high
By six meters, 50 wide
And about another meter thick.
That makes about 20-odd tons.
-Minimum? -Minimum, yes.
-That's right. -Tsoukalos: This is incredible.
So, this is one of the largest
-Freestanding stones? -It is.
I mean, you know, when I see stuff like this,
-That's when I wonder, you know, how... -Yeah, h-how did they carry it?
-Was... -How did they-- they quarried it, in this case.
-Yes, they must have quarried it. -And put upright.
And then put it upright, yes.
Narrator: While visitors to these islands are immediately struck
By the massive megaliths,
One of malta's most incredible structures remained hidden
For centuries.
In 1902,
Construction workers accidentally discovered
One of malta's most curious features,
A mysterious underground sanctuary dating to 2500 bc.
Called the hypogeum,
The subterranean structure
Was revealed to be three levels deep,
All hewn from solid stone.
Jeff williams: How could people from that far back,
How could they know how to construct such a thing?
But if you look at some of the chambers,
It looks like it's actually been carved
With some type of a laser.
So I don't-- I don't know exactly how it was done,
But I do know that they had a technology
That far exceeds what we have today as far as stonecutting.
Tsoukalos: If you look at the way some of these walls have been cut,
There had to have been a type of plan
Or construction plan beforehand.
And one has to wonder if that engineering knowledge
Was imparted upon the builders,
Which were our ancestors, by extraterrestrials.
Narrator: Could the incredible stonework found at the hypogeum
Have been achieved using extraterrestrial technology?
Curiously, the first archaeological investigations
Performed at the site in 1907
Turned up more than 7,000 skeletons.
And according to a national geographic magazine article
From may 1920,
Many were found to have unusually long skulls.
In 2014, I had the great privilege
Of looking at five of these elongated skulls,
And they were very interesting because one of those skulls
That I looked at had a missing sagittal suture.
Narrator: The sagittal suture connects to the sides
And roof of the cranium.
This suture is open when a person is born
And closes around the age of 35.
As you can see, even from the inside,
There's no sign of the middle suture.
-Right. -Completely fused.
Tsoukalos: That's fascinating.
Even if you have a suture that ossifies or fuses together,
You still have a fine line
That you can discover or detect.
And with the one skull that I was able to look at in malta,
That suture was completely missing.
Narrator: Enormous megalithic structures
Built more than 5,000 years ago.
A mysterious underground sanctuary hidden for centuries.
Ancient skulls of abnormal size and shape.
As far as ancient astronaut theorists are concerned,
The evidence all points to one conclusion,
That the islands of malta were once home
To extraterrestrial beings.
There aren't many places on earthind-blowing.
That can turn modern archaeology on its head
Like the next mysterious site on our countdown.
It's a place that mainstream science says
Can't possibly exist.
But not only does it exist,
It may even provide evidence
Of the great flood described in the bible.
Number seven on our countdown of the top ten mysterious sites,
Gobekli tepe.
♪ ♪
Narrator: Sanliurfa, turkey.
October 1994.
While plowing his field,
Shepherd savak yildiz spots a strangely shaped stone
Protruding from the ground.
After brushing away the dirt,
He realizes that it may be part of a much larger object.
It wasn't until german archaeologist klaus schmidt
Visited the site and began digging
When they realized what was really at this site.
William henry: What he discovered was mind-blowing.
After discovering the first t-shaped pillar
Buried at the site,
He soon found more of these massive structures.
Narrator: Klaus schmidt had the sediment layers
Of the site radiocarbon-dated.
The results indicated that the stone structures
Could be as much as 12,000 years old,
More than 5,000 years older
Than mankind's first known civilization in mesopotamia.
Some researchers propose, the megalithic structures
Provide evidence that an advanced civilization existed
On earth many thousands of years ago,
One that was assisted by otherworldly visitors
Before falling victim to a deadly cataclysm.
There is evidence of a great cataclysm
That took place around 12,900 years ago.
It's called the younger dryas impact event...
...Where comets and air bursts
Impacted the land and the ice sheets,
Causing massive flooding.
I mean, gobekli tepe dates to the time
Of the younger dryas events that were taking place
Over a few thousand-year period.
Andrew collins: Gobekli tepe could be the smoking gun
Of a lost civilization,
'cause it confirms that, at the time of the last ice age,
There was high culture existing in the world.
This is something that had been speculated for many years.
If you think gobekli tepe is one
Of the most mysterious sites on earth,
There's another that I think is even more baffling.
It's a series of massive stones in northern France
That have been arranged in a very deliberate
And perplexing geometric pattern.
Even modern archaeology can't explain their purpose.
At number six on our countdown of the top ten mysterious sites,
The standing stones of carnac.

Narrator: On the northwest coast of France,
Just south of brittany,
Lies one of the most important prehistoric sites
In europe.
At the seaside village of carnac,
Over 3,000 megalithic stones are placed in rows
Over two miles long.
The carnac stones were hewn from local rock formations
And erected between 4500 to 2500 bc,
At the end of the stone age.
They are the largest collection of standing stones in the world.
Archaeologists are baffled
By the many megaliths at carnac here.
It's clearly a massive construction project,
With blocks of granite weighing 50 to 100
To even up to 350 tons.
Narrator: Although mainstream archaeologists speculate
That the carnac stones are most likely tomb markers,
Ancient astronaut theorists believe
These stones are intentionally laid out
In a unique geometric formation.
Robert schoch: The carnac stones were laid out incredibly precisely
Using standard units of measurement
That show very sophisticated mathematics.
It's been suggested
That they were using the pythagorean theorem
Thousands of years ago.
It may elude us now,
Exactly what they were trying to accomplish,
But it seems like they were encoding
Some kind of information.
Narrator: The pythagorean theorem
Wasn't established until 2,000 years
After the last carnac stones were erected.
So how could the builders have possessed this knowledge?
And why were the stones arranged
In such precise geometrical patterns?
Childress: The carnac stones are
A perfect marker for any kind
Of aerial vehicle looking down on the earth.
Von daniken: The extraterrestrials told our ancestor,
"do this. Move stones.
Put it exactly in this pattern. We order you."
It was on purpose.
The idea was that generations in the far future
Will start to ask questions.
That's the situation we have today.
Narrator: Could the carnac stones contain a mathematical message
Left by extraterrestrials?
Ancient astronaut theorists say yes
And suggest further evidence can be found
By examining a famous megalithic site to the north.

To be an exact replica of our solar system.
Number five, stonehenge.

Narrator: Wiltshire, England.
The neolithic monument known as stonehenge
Has dominated the landscape here for no less than 5,000 years.
The iconic stone circle consists of vertical standing stones
Towering 13 feet tall
And weighing 25 tons each,
Topped by connecting horizontal lintel stones
And surrounding a smaller ring of stones in the center.
Newman: Stonehenge is unlike any stone circle anywhere on the planet.
It's perfectly circular. It has lintels above it.
It's designed with precision-engineered
Astronomical alignments.
How could the ancient stone age people of britain
Move these stones into place?
Narrator: However stonehenge was constructed,
It involved moving much more than just the stone blocks
That stand today.
According to researchers,
This is just 25% of the original monument...
...The center of a much larger structure
That was surrounded by multiple concentric circles
Constructed over a period of more than a thousand years.
John martineau: So, stonehenge is very interesting
In that it evolves over a very long period of time.
And the first thing that goes up at stonehenge
Is not there anymore.
It's the 56 holes that today are known as the aubrey circle.
It used to be filled with 56 stones in a big stone circle
Just inside the henge.
Tsoukalos: Stonehenge is a replica
Of our solar system on earth.
Each circle corresponds with one of our planets
Inside our solar system, including pluto.
So, now we have a structure that's at least 4,000 years old,
And our ancestors knew about pluto?
Without telescopes?
Someone told them about pluto
And all of our planets in our solar system,
And that is the message.
Because, in neolithic time,
There is no way that they knew about this.
As amazing as stonehenge looks today,
Remember, what's still standing
Is only a fraction of the original structure.

Narrator: In April 2018,
Ancient astronaut theorist giorgio tsoukalos,
Egyptologist ramy romany,
And archaeoastronomer dr. Giulio magli
Traveled to cairo to investigate
What is perhaps the most impressive structure
Ever constructed on earth,
The great pyramid of giza.
(grunts)
This is...
-Look at the size of this thing. -...Incredible.
Romany: Every single block is bigger than this car.
Tsoukalos: Yeah. It is insane. It really is.
Romany: Are you ready for some climbing?
Tsoukalos: I have goose bumps on my calves right now.
Narrator: Built from more than two million limestone blocks
Each weighing thousands of pounds,
The pyramid is aligned perfectly
To the cardinal points of the compass--
North, south, east and west--
Suggesting that its builders possessed
Extraordinary geographical knowledge.
According to mainstream egyptologists,
The great pyramid was built sometime around 2500 bc
As the burial tomb of the pharaoh khufu.
But this claim has yet to be proven.
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.
The pyramids have no real explanation
Of what their purpose was.
Narrator: But if the pyramids at giza were not intended
To house the remains of dead pharaohs,
Then why were these towering monuments built?
In his 1998 book the giza power plant,
Noted machinist and engineer christopher dunn
Proposed that the shape, positions of chambers,
And proximity to underground rivers indicate
The pyramids of giza functioned as ancient power plants.
This incredible hypothesis,
Which has since been adopted
By other scientists and researchers,
May be impossible to ever prove.
But ancient astronaut theorists believe new information
About the great pyramid may soon be revealed.
In March 2016,
Archaeologists examining the ancient structure
With a new technology known as muography
Made a shocking discovery,
A mysterious chamber inside the structure
That is as large as the statue of liberty.
This new room is only the beginning of it.
I'm sure, within the next months or at least two years,
They will discover more rooms in the great pyramid.
I personally think that the great pyramid in egypt
Holds some sort of time capsule.
Narrator: Perhaps what lies within the great pyramid
Will reveal not only incredible truths about ancient egypt
But about the history of humankind.
Could there be clues that reveal
That egypt was once home to an extraterrestrial civilization?
High in the mountains of peru lies a city
With monumental walls so tightly joined

Number three on my countdown
Of the world's top ten mysterious sites,
Sacsayhuamán.
♪ ♪
Narrator: Cuzco, peru.
On the northern outskirts of what was once
The capital city of the inca,
At an elevation of more than 12,000 feet,
Looms the ancient fortress of sacsayhuamán.
Mainstream archaeologists suggest
The inca built this megalithic site in the 15th century ad,
But many researchers now believe
That the foundation of sacsayhuamán
Dates back centuries earlier.
My feeling is that we're looking
At a two-phase, uh, construction site
In many of the so-called, uh, inca stone monuments
And that the inca structures sit on top
Of much more ancient rock-cut structures
And megalithic structures
That we just don't know who built them.
And this actually fits with the incas' own view.
Narrator: Like many inca sites,
Sacsayhuamán features astonishing stonework
But not all of it credited to the inca.
According to conventional archaeology,
The killke culture built the older sections of the site
Approximately 1,000 years ago.
But the inca themselves believed
The site was constructed by an earlier, unnamed race of people
Led by a powerful god who descended from the skies.
Throughout time, there has been witness
To a god named viracocha
That visited the south american people
And blessed them and gave them all types of technology.
Some of his physical characteristics
Make him stand out from the indigenous population,
Because he was not at all similar
To the indigenous people.
Viracocha was the primary deity of the andes,
Going back many thousands of years.
He was thought to be the founder
Of all the ancient sites we see in peru and bolivia today.
Narrator: But did viracocha actually exist?
Could he have been, as ancient astronaut theorists suggest,
A visitor from an alien world?
If so, it might help to explain
Just how the ancient site was constructed.
It's amazing, all these, uh...
The-the weight of the stones.
Hancock: The walls are put together with blocks of stone
Weighing 50 or 100 tons...
...Cut and shaped like the pieces of a jigsaw puzzle
So that they lock together so tightly
That you can't even get a sheet of paper between them.
Narrator: According to local legend,
A bird was responsible for the seamless construction.
Legends say the winged creature carried
A powerful chemical in its beak,
A substance capable of melting stone.
Narrator: But is it possible, as ancient astronaut theorists suggest,
That the mythical bird might actually have been a spacecraft,
Piloted by alien visitors known to the locals as space brothers?
Many of the sites we've featured on my countdown are famousweight

The ruins of baalbek.

Narrator: Eastern lebanon.
The bekaa valley.
Here at this archaeological site
Stand the ruins of heliopolis...
...Built in the fourth century bc by alexander the great
To honor zeus.
But beneath the corinthian columns
And remnants of both greek and roman architecture
Lie the ruins of a site that is much, much older.
According to archaeologists,
It dates back nearly 9,000 years.
The ancient city of baalbek,
Named after the early canaanite deity baal.
Hanan charaf: Baal is the god of life, the god of the sky, the god of the sun.
He was the god that was venerated on the site of baalbek
During the canaanite and the phoenician times.
Robert mullins: And so, because it was already sacred
To the god baal,
Then later the greeks and the romans
Then would build temples on this very same spot.
Narrator: Archaeological surveys have revealed
That the enormous stone foundation that lies
At the base of the site dates back thousands of years.
Baalbek, as we know from the archaeological evidence,
Must have existed during neolithic period,
Between 6,000 to 8,000 years or even 9,000 years bc.
Narrator: But even more significant to ancient astronaut theorists
Is their belief that the colossal stone platform
May have been built using extraterrestrial technology.
As evidence, researchers point
To the gigantic megalithic stones
Incorporated into the foundation,
Each weighing between 800 to 1,600 tons
And perfectly fitted together.
In baalbek, stone blocks were transported
Which have a weight of over 1,500 tons.
And this not in a flat land.
It's all mountain.
We have absolutely no idea how such heavy loads
Could have been transported in the mountain.
I have nothing but a speculation to this.
But for sure it does never fit
Into the prehistoric knowledge of our ancestors.
This is the real mystery of baalbek--
How these stones came to be there,
Why they were placed there, and specifically
How they were transported into place.
Because some of the stones are of such magnitude
That modern machinery is incapable of putting them there.
But somehow our ancestors were able to do this.
Birnes: It is one of the oldest, oldest megalithic sites on the planet.
And it has these huge stones laid out
In a precise geometrical shape
At a time when the prehistoric people
Who would have lived there
Would have no concept of how to move stones of that nature.
Narrator: But if the moving, hoisting and setting
Of such massive stones was so incredibly difficult,
Then who, or what, helped to place them there?
And, perhaps more importantly, why?
We know that the ancients always went to power places,
And baalbek clearly is one of them.
It is a place where the gods were worshipped,
Where the gods were said to be present.
And so, when it comes to baalbek,
This platform was built there for a reason.
For what purpose it was used
Is a question we can't answer at this moment in time.
But what we do know is that whatever was happening there
Had a great religious significance to them
And was linked with worshipping deities,
Deities which clearly are of an otherworldly origin.
Hopefully, at one point,
Archaeology will be so open-minded
That they actually want to explore this further.
We're just moments away from the top site on my list.

We've definitely saved the best for last.

We've finally reached number one on my top ten countdown
Of ancient aliens' most mysterious sites.
Lying in ruins atop a vast plateau in the andes mountains
At an altitude of over 12,000 feet,
The megalithic stones found at this incredible location

That extraterrestrials visited our planet
And changed the course of human history.
My number one most mysterious site, puma punku.
♪ ♪
Narrator: Bolivia, south america.
Here lie the mysterious ancient ruins of puma punku.
Spread across a desert plateau
Are dozens of megalithic stone blocks
Cut with extreme precision
And some weighing more than 100 tons.
These are the mysterious ruins of puma punku,
Nearly 13,000 feet in the altiplano of bolivia.
What you have here are massive blocks of granite
Scattered like some kid's toy blocks around the site.
Archaeologists are baffled by what puma punku was,
How it looked, and what the purpose
Of this enormous structure would have been.
Narrator: What sets puma punku apart from other ancient megalithic sites
Is the incredible stonework,
Which some researchers suggest is far too sophisticated
To have been accomplished using primitive tools.
One of the amazing things here at puma punku
Is the precision of the blocks.
You can see with this block of granite
That it's really been cut at very accurate right angles.
Not only do these granite blocks have precision corners
But they also have these difficult drill holes
That are going right through the rock.
Narrator: Mainstream scientists believe
The site was originally constructed
About 2,000 years ago.
But in 1945, archaeologist arthur posnansky proposed
That puma punku was much, much older.
By examining the structures and what he believed
Were their original alignment with the stars,
He dated the ruins to 15,000 bc.
But how could such primitive people,
Living perhaps over 10,000 years ago,
Have produced such flawless stonework?
Von daniken: The spanish conqueror asked the inca,
The people living there, including the king of the inca,
"what is this puma punku?"
And they all said, "it's not us.
"it's not our forefather who make this.
These were made by the gods in one single night."
Tsoukalos: One of the earliest chronicles that we have
In regards to puma punku talks about that these giant platforms
Were moved through the air by the sound of a trumpet.
They basically floated into place.
And here's another very interesting thing that,
According to the myths, this is exactly what happened
With the moai on easter island.
Narrator: Could it be that the local traditions of easter island
And puma punku tell nearly identical stories of levitation
Because the ancient people at both sites witnessed
The same extraterrestrial technology?
And if the stone blocks of puma punku
Were once part of a megalithic structure,
How did it end up in ruins?
I honestly believe that puma punku
Is more than 12,000 years old.
12,000 years ago, there was a global cataclysm
That destroyed a lot of ancient sites that we find,
Whether in egypt or the altiplano of bolivia.
We had, at the end of the last ice age,
All kinds of catastrophic flooding
Due to the events in the climate changes
And the melting of the glaciers and increased precipitation.
There were incredible rises in sea levels
Since the end of the last ice age.
More than 12,000 years ago,
Lake titicaca was 100 feet higher than it is today.
And I believe that puma punku
Was literally on the shore of the lake at that time,
Whereas now it's eight miles away.
12,000 years ago,
It was hit by a wave of mud coming from lake titicaca
As a tsunami.
Narrator: A megalithic structure built more than 12,000 years ago
With the help of extraterrestrial technology
Destroyed by a great cataclysm.
If this incredible story is true,
One question still remains.
What was puma punku?
Childress: When you look at the complexity of puma punku,
The huge platforms, the interlocking blocks
That was made into what they thought
Were indestructible walls...
...What you could have is
A kind of perfectly made granite spaceport
That extraterrestrials would want.
Although the origins of many of the incredible sites
We've featured on ancient aliens continue to be debated,
To me, puma punku is so extraordinary
That it is the one site where I will say, yes,
This was likely built directly by the aliens themselves.
But make no mistake,
Each and every one of the sites on our countdown
Deserves to be investigated with an open mind.
And it is only by asking the questions
That we can finally uncover the truth
Of our extraterrestrial origins.
