Oh, it is more than vetted from many archaeological finds and DNA itself. I speak in terms of established Linnaeus phenotype classification of Negroid populations that only existed south of the Sahara and was a natural barrier to migrations, and was known to be a huge threat of enslavement. Even the Ethiopians do not consider themselves as Negroid, but were a people, who long established trade along the Nile River with Egypt. Even they recognize themselves as not the same people as of ancient Ethiopia. You seem to believe in the absurd narrative that somehow the same people today are the people that populated the ancient lands of Egypt. They're not.
