Maybe so but that is probably a minor part of the whole story. The site may be 5,000 or more years older than 2900 BC. I watched a show about a pit of burned human bones dug up there around 1900, studied, placed in a leather bag and reburied in the same hole. They weren’t the elite.
I was watching history channel or something and some historian said the common idea that in prehistory that every worked together for everyones benefit and there were no classes is not holding up with the evidence being dug up.
