You should start a thread on the Sumerian-Hamitic historical connections, including the relationship between the Mesopotamian ziggurats and the Ancient Egyptian mastabas.
Apart from relatively late Semitic influence...the civilizations of Africa are the civilizations of the Hamites, its history is the record of these peoples and of their interaction with the two other African stocks, the Negro and the Bushmen, whether this influence was exerted by highly civilized Egyptians or by such wider pastoralists as are represented at the present day by the Beja and Somali.
