>If not inventing anything, not building anything, not leaving any textual evidence of your existence
For one, we can say the same the about Europe all the way up to the 1600's. Sure, the Greeks wrote texts but they were heavily influenced by the cultures around them. Even their alphabet came from the Phoenicians who based it on an earlier Semitic script called Proto-Canaanite, which was influenced by Egyptian hieroglyphs. So yes, it all comes back to Egypt.
But lets look at how illogical your claim is. You're saying that these civilizations whom were around for thousands of years never invented anything. Not a single thing? No mathematics, no hunting gear, no writing, no stories, no poetry, no music, no buildings, no laws, no religions, no agriculture, no metallurgy, etc. Not only is that utterly moronic, it is also completely false. What you mean is that South- and central African inventions did not influence Europe directly, because Europe took all their knowledge from North-Africa and Asia.
The issue isn't that they did not invent or advance anything, the issue is that you've never learned about global history. Your view is Euro-centric, when it should be human-centric.
