Looking at the linked pic of the model of the city of Viminacium, it is incredible to me how anyone can deny the possibility that another advanced civilization could not have preceded the Egyptians.
That stated, we should “mind our Ps & Qs”, so-to-speak.
There are examples around the world. Aztecs & Incas are but two others.
I’m not arguing the point, but I don’t see the connection.
