UBU.
By the way.
Are you one of those who believe in the theory of (macro) evolution?
Usually, going hand in hand with that belief is a disbelief that all humans descended from the same man, the first man, Adam.
Are you also one of those who do not believe this?
Someone in the New Testament said, “Concern yourself not with endless genealogies”
BTW endless means it goes back a long, long time..
All humans descended from Adam.
The fact is that we have human cultures before 4000 BC, whether at Gobekli Teoes, pre dynastic Egypt, the indus valley, or in Australia
