@konstantin To me it seems as though there must have been a great civilization, long ago in the past, that by disaster declined and got fragmented. When you look at how old Gobekli Tepe is suppose to be, it's hard to believe it was made by hunters and gatherers. The ancients seem to be so obsessed with astronomy.
There are many archaeological finds that speak of the high development of ancient civilization. I think there was some lifting, and then the result of unknown circumstances led to a decline or degradation.
