Sincere question. I'd just wondered if there was a clear consensus?
As far as I'm aware of, I can say that NO, there, still nowadays, DO NOT EXIST ANY CLEAR CONSENSUS, both about
datation and also about to which culture/s does really (may) have builded it.
Dozen (and even more) hypothesis has been made and released. BUT NO ANY CLEAR CONSENSUS HAS TAKEN PLACE YET
Nice and Bright Day
You can not solve a problem with the same kind of thinking that you used to create it.
