Well there's nothing to suggest this city build by neolithic farmers were any more advanced than neolithic farmers. And we already knew there were
neolithic farmers living in the region at the time
Of course,there's also no reason why neolithic farmers couldn't have built the Sphinx. But this discovery doesn't affect orthodox Egyptian
chronology in any way.
(I do think the term 'city' may be a bit misleading though)
For Neolithic farmers being compared to the Greco-Roman period isn't bad, they were around in 150BC these guys are 5,000BC and having houses in
dressed limestone isn't bad either.
I'm just saying it's a 'possible' link to a theory that's out there, I'm not saying its true, just posting a piece in a puzzle (orthodox or
not).
And the term 'city' is what they used, I was just quoting the source, it could of course be wrong.
