Around 7000 years ago, we believed there was a population boom.

And that's what we see today.

I mean, these are the people who actually survived over the last

7,000 years, although if you look at Arabia today and compare it to 7,000 years ago, of course, it was a much different place.

I mean, you had much greener places in Arabia than what you see today.

You know, there's still small communities, as I said, so you don't see very large communities and mostly around places where you have water.

Of course, there were a lot of lakes.

So they were more nomadic, and actually they kept the name.

We believe the name Arabia, which is also a term that needs to be studied extensively.

It's to describe nomadic people who lived in Arabia.

So I think that's how these people lived.

They moved around these lakes, around places where there is water, and the remnants of those are these oases that you still have today in Arabia.

Yes, it's not a straightforward answer.

No, absolutely not.

I think the nomadic lifestyle of Arabia has dominated most of the last,

three, four millennia.

You know, they moved from one place to another.

You know, after 6,000 years, actually Arabia started to become more arid and more desert up until today.

So yes, people, their movement were a bit difficult.

They moved with difficulty because of sustainable land actually shrunk.
