"Perhaps the synergy of cultural trade brought about the difference? The Eurocentric model has been profoundly dealt a blow since there's little evidence of IndoEuropean genetic flow into Egypt. However, we cannot deny the potential of the impact of trade. Traveling Hebrews spreading ideas that when mixed with the indigenous African technologies produces something new and unique."
My response:
"What were these Hebrew ideas that mixed with 'indigenou African technologies' to produce 'something new and unique'?"
In the meantime...
Someone else responded to Osirion's statement, something to the effect of there being advocates of the notion of enslaved "Hebrews" having built the Pyramids. Aside from lack of real substantian on the notion of "slaves" building the Pyramids, much less those "slaves" being a large population of "Hebrews" or "foreigners", even if we were to assume that this was the case, how does this in any meaningful way make the Pyramids a "Hebrew" or "foreign" technological thought. As we are already aware, the predecessors of the Pyramids can be found in the form of 'mustabas' or 'mounds' in pre-dynastic elite burials of the Nile Valley. How come we don't have Pyramids of these kinds in the Levant? This is a question that one needs to give some consideration to.
Indeed, the Nile Valley or any other cultural complex for that matter, doesn't exist in a vacuum. As such, when people of different cultures or regions come into contact, flow of or exchange of ideas is to be expected. With that said, it would be interesting to know the specifics of the ideas that "Hebrews" spread into Egypt, and how, this supposedly produced 'something new and unique', and as to when this 'something new and unique' came about!
