The theories of man starting in Africa went to the trash a long time ago.
Man himself is much older than that old migration pattern theory shows.
The answer is, we do not know. How smart is that ?
Evidence show us that the great pyramids and Spinx are probably 12,000 years old but we have no human remains of that time period. In that area anyway.
There are plenty more pyramids than those in Egypt. Just less known.

Most folks vision of history is limited to their cultural upbringing and religion that went with it.
There is plenty of evidence of worldwide trade before Christ Helios but why does it escape the history books.

And everyone 'THINKS' they have a grip on history...
I could go on for days on this stuff. And yes, I have studied these old languages enough to read some of them. Being able to speak the sounds has nothing to do with understanding the content and context of what is being said. That takes a very long time.
Everyone needs to re-think what they think they know of history.
