There were like one to four million.

Those are the estimates on the whole planet.

And they were usually living in small communities of like 100 people up to 500, not more.

So the problem then is, again, inbreeding.

Inbreeding means it's a degeneration.

So it's a problem.

We are genetically not so diverse, actually, as humans.

But Gobekli Tepe, people were meeting from different areas, having sex with people they usually wouldn't see, creating healthy children.

And Gobekli Tepe was working for 1,600 years.

And I think it was like an evolutionary kind of machine.

Like without that idea, we're going to create like

a fucking place or a party place.

It was a party, basically.

They were eating very well.

They found a lot of bones, but no one lived there.

They just came together there for parties.

And then after 800 years, they start making beer there.

And then the situation slightly changes.

They found these places where they made beer.

You can still find the chemicals and it's sure that they made beer there.
