Decoding Gerçek Tepe 00:09:43
The lives of archaeologists have always been pained by the mass media's adoration of alternate historians.
A handful of authors who believed that Atlantis was real, or that ancient aliens were real, or some version of the narrative that there was some advanced civilization on Earth predating our own.
Gerbekli Tepe is an archaeological site in Turkey that has some genuinely strange things about it.
And it's one of the darlings of the alternate historians.
What is really going on with this place?

Decoding Gerbekli Tepe On a high ridge among the dry rocky hills of southern Turkey is a mound, a long gradual mound of stones and debris that you might not even notice.
In the 1960s, an American archaeologist came upon it, noted what he took for Neolithic gravestones and broken bits of Byzantine sculptures, sent in a survey, and moved along.
But since then, others have taken a closer look.
Teams of scientists have descended and dug and uncovered what many have described as the most astounding and out-of-place find in the history of archaeology, indeed in the history of humanity.
In Turkish, it's called Gerbekli Tepe, Pot Belly Hill, an ignominious name for such a stupendous find.
Today, we're going to turn a shovel full of rubble of our own, gaze upon the wonders, and ponder how some say the site cannot be reconciled with human history.
The neat thing about Gerbekli Tepe is that if you go there, or even just look at pictures of it, there's something immediately weird about it that stands out, and you don't even have to know anything about archaeology to see it.
Most of the site looks just the way you'd expect any ancient ruins to appear.
The remains of low stone walls showing the outlines of where structures once stood, excavation trenches where archaeologists have exposed these walls, wooden catwalks allowing people to walk around without disturbing the ruins.
But scattered everywhere throughout the site is something you've never seen anywhere else.
Great white monoliths of limestone, most rising higher than the battered old walls, many in excellent condition.
They seem desperately out of place and far too precisely cut to have been associated with the surrounding rubble.
They're roughly the dimensions of giant dominoes, but slightly T-shaped with tall stubby arms at the top.
called the T Pillars by archaeologists.
They range from under two meters to over five meters in height and weigh up to 10 metric tons apiece.
The T pillars are exquisitely decorated, all in relief where the image projects outward from the flat surface.
Most are depictions of local animals of every variety.
A few are even wonderfully rendered three-dimensional sculptures of boars crawling down the side of the T-pillar.
The pillars are arranged in circles up to 10 meters in diameter, and inside each circle are the two tallest pillars.
Four of these circles have so far been excavated at the site, but the indications are that the site includes at least 20.
This uncertainty is due to what is archaeologically the most surprising thing about Gerbekli Tepe, and it's not the pillars.
It's that the entire site was deliberately buried with rubble very soon after completion, and new circles of pillars were built on top of the rubble of previous ones.
Thus, when it was discovered, the site was one giant low mound, almost 20 acres in size and some 15 meters high.
Only about 5% of it has been excavated so far.
The site was first discovered and described in 1963, but little serious work was done until 1994, when it was taken over by Klaus Schmidt of the German Archaeological Institute, who remained the principal investigator until his death in 2014.
Schmidt's most historically significant discovery was one of the earliest.
The site's age, determined by radiocarbon dating of wood, charcoal, and animal bones, to be 11,500 years ago.
Gerbeikli Tepe was built slightly earlier than 9,500 BCE, with an error range of a few centuries.
This was at least 6,500 years before the first earthworks at Stonehenge.
Until this date was established, previous thinking had been that Neolithic populations who subsisted on hunting and gathering would not come together to build great monumental works.
Yet, the construction of Gerbeikli Tepe clearly required a lot of workers for a long time, which would require a change in our understanding of the development of human cultures.
Now, when there's a paradigm shift like this in any science, there are two basic ways you can react to it.
First, you can do what anthropologists and archaeologists did.
They peer-reviewed it to verify the data was correct.
Then, when it passed muster, they threw parties and celebrated a rare significant shift in our understanding and got to work updating the textbooks.
The other basic type of reaction is to do what crackpots from outside the world of science did.
To gloat that new information like this proves that the scientific method is fatally flawed and hopelessly unreliable, and therefore, any alternative models are valid.
This was the path chosen by many in the alternative science community, including ancient alien theorists and others.
Two of these alternative theorists were Graham Hancock and Andrew Collins.
In his 2015 book, Magicians of the Gods, The Forgotten Wisdom of Earth's Lost Civilization, Hancock asserted that Neolithic people of the day did not know either stone masonry or farming.
Thus, they had to have had help to create Gerbeikli Tepe.
He described his belief to the show London Real.
It's obvious to me that that wasn't a group of hunter-gatherers who woke up one morning suddenly equipped with the skills.
What we're looking at is a transfer of technology.
This was the survivors of a lost civilization.
They already knew how to create megaliths.
They already knew how to do agriculture.
They settled amongst a hunter-gatherer people who they may have reached out to before.
They settled amongst them and they created this project.
And this project was to restart their civilization.
In a world that can feel overwhelming, spreading thoughtful, evidence-based content is one of the best ways to make a positive impact.
Ask your local public radio station to air the Skeptoid Files, a 30-minute radio-friendly version of Skeptoid that pairs two related episodes promoting real science, true history, and critical thinking.
And in these challenging times for public media, we're offering these broadcasts for free to radio stations, available on the PRX Exchange or directly from Skeptoid Media.
It's an easy ask.
Just send a quick message to your station's programming director.
By helping to bring the Skeptoid files to the airwaves, you'll help promote the essential skills we all need to tell fact from fiction.
Just go to your local station's website, find the programming director's email address, or just their general email address.
You can even use the telephone.
I know that might sound crazy.
It's an old legacy device that allows real-time voice communication.
I know that's weird, but hey, it's an option.
The world can feel chaotic, but you're not powerless.
When you promote critical thinking, you can help your community tell fact from fiction.
And that's how we shape a better future.
In uncertain times, spreading good ideas can make you feel helpful, not helpless.
Let's stand up for reason, truth, and understanding together.
Get them to air the Skeptoid files from Skeptoid Media, available on the PRX Exchange, and they'll know what that is.
Ancient Lives Were Rich 00:07:21
Although their respective beliefs about Gerbakli Tepe are so different as to be irreconcilable, Hancock and Collins both hinge their notions upon a single event, a highly controversial idea called the Younger Dryas impact hypothesis.
The Younger Dryas period was a 1,200-year interruption to the gradual climatic warming ever since the gradual recession of ice from the most recent ice age began, around 20,000 years ago.
The period began about 12,900 years ago and lasted until 11,700 years ago, by which time temperatures had returned to near-normal.
And that's just a few centuries before the construction of Gerbakli Tepe.
A return to normal after an ice age is a very complex climatic event, filled with oscillations and causes and effects, and the Younger Dryas was only one of at least three such interruptions.
There are four main hypotheses for its cause.
The overwhelming favorite is a shutdown of the North Atlantic conveyor, an important current that moves warmer waters farther north.
This explanation fits best with what we know of the climate.
However, there are at least three competing hypotheses, all of which have much less academic support and all have significant problems.
They are a barrage of comet impacts, the eruption of the Locker Zee volcano in Germany, and a supernova in the constellation Vela that may have depleted the ozone layer.
Hancock and Collins both adopted the comet impact, hypothesizing that it caused nonspecific worldwide cataclysms that lasted centuries.
While neither author offers a compelling explanation for the 1400-year gap between when the supposed barrage would have taken place and when construction began, both rely on it as the crucial element that explains Gerbekli Tepe.
Hancock believes this alleged cataclysm was what destroyed his ancient advanced civilization, which Gerbekli Tepe was an attempt by a few survivors to restart by training the primitive local population.
While Collins believes that the comets so terrorized the people that they felt they needed a megalithic structure and pilgrimaged here from all over the continent.
As he explained to the program, megalithomania.
And my personal belief is that they were in an age that followed a major catastrophe that had affected large parts of the Earth and that they were essentially in fear that if they did not do something extra special, then these bad things that had happened in the world would come back again.
I think Gerbekli Tepe was probably used by those that enter inside the different enclosures and monuments that are there.
I think that they were interfaces between two different worlds, the world that we live in and the so-called liminal world or the spiritual dimension.
Hancock and Collins, as well as pretty much all the other Gerbekli Tepe alternative theorists, also point out various astronomical alignments with the structure, plus inscriptions that they interpret as advanced written language.
Neither claim is accepted by archaeologists.
Beyond that, they simply exaggerate nearly everything, adding a few feet to the heights of the T-pillars, adding anywhere from a few to several tens of tons to their weight, always rounding up the structure's age a thousand years or so, and so on.
It's not the style of a careful researcher seeking to accurately characterize a discovery.
It's the style of a showman trying to sell books and sound sensational.
Was Gerbeikli Tepe truly so incompatible with what we thought we knew that barrages of comets and ancient advanced civilizations must be introduced into our theories to explain it?
When Stanford archaeologist Ian Hodder told Newsweek in 2010 that, quote, it changes everything, all our theories were wrong, end quote, he didn't mean that we must throw the door so wide open as to admit any and all hypotheses, no matter how outlandish.
He was speaking within a narrow scope of uncertainty about when and how megalithic structures that brought many people together fit into the lives of Neolithic people.
And nothing more.
Klaus Schmidt, Gerbekli Tepe's longtime lead archaeologist, always believed the site was a religious temple.
Other researchers have not agreed that the evidence supports such an identification.
Moreover, we've since found at least eight other sites in the region with similar T-pillars that date from the same time period.
Their purpose remains, to us removed so many millennia, essentially unknowable.
The people had no written language to tell us anything.
We can see from the spearheads and bones left behind that they ate wild animals there and did not domesticate any.
We can see from the lack of trash piles that nobody lived at the site.
We see the tools they left behind and the quarries to see how they did the work.
And we can see what they built and when, and very little else.
As to the speculations by the alternative theorists that hunter-gatherers would not have built such structures without clear direction or instruction or purpose, archaeologist and author Dr. Ken Fader finds that this was not necessary after all.
From his Encyclopedia of Dubious Archaeology.
That question itself, however, is based on a misconception about ancient people, that they were trapped in a way of life that required their complete focus on utilitarian things, the mundane elements of subsistence, and therefore had little or no time for art or ideology.
This simply is false.
Time and again we see in the archaeological record evidence that even people who we might have thought were barely able to eke out an existence by hunting and gathering had in fact led rich lives filled with ritual, broad social networks, creativity, artistic expression, and monumentally scaled construction projects.
So, in short, give our ancestors some credit.
Credit them for what they did and what they left us.
When someone tells you humans weren't smart enough or ambitious enough to have done something, and therefore must have had help from aliens or Atlanteans or whoever, look instead to the evidence.
You'll probably find that humanity, whether that of your ancestors or even your own, is a powerful force indeed.
But nowhere near as powerful as our premium supporters like Eric Peterson, Cal Kellogg, Dr. Stranger, and Jeff-François Letourneau.
