Actually all those countries except Sudan are technically Sub-Saharan. Though I do get your point being that there is more than one type of black African and that cacs always try to pigeonhole us into thinking there can be only one type of "true negro" and that everyone else is Caucasian. This is a classic white supremacist tactic.
Nonetheless check out my last post. I lay it out pretty clearly why the word Sub-Saharan is comical to use in reference with the Ancient Egyptians because around the time of the origin of Ancient Egypt, the Sahara was a lush savannah that had a lot of Africans living in it. These Africans were the ancestors of the Ancient Egyptians.
Thus even mentioning the word Sub-Saharan in this conversation is stupid. The better question is whether the Ancient Egyptians originated from a native population of black Africans. And the answer to that question is undoubtedly yes. There is no evidence of a non-African origin to the Ancient Egyptian civilization. In fact all evidence points to Ancient Egyptian originating from Africans who originally lived south of the Sahara Desert but migrated north about 10,000 years ago when the climate in North Africa changed and the Sahara Desert became a lush savannah. Then about 7,000 years ago the climate changed rapidly again turning the Sahara into a desert. This is what forced those Africans who originally came from the south to migrate to the only oasis left in North Africa at that time. And that place was the Nile Valley.
If anyone is interested in this, there is a great book by a white man named Robert Bauval called BLACK GENESIS: THE PREHISTORIC ORIGINS OF ANCIENT EGYPT.
Go check it out.
My father had that book. Now that he's passed it's mine.
Can't BELIEVE any self respecting black person would ever fall for that "Ancient Egyptians were white" bullshyt. It's a literal impossibility
