once I saw a documentary on TV. So all africans are black. But a minority crossed the Persian Gulf into Yemen, when the ocean was lower in the Ice Age. They spread into Europe and Asia later. But first, they settled in a special region: a small depression by the ocean coast. Where the sea winds brought plenty of rain. There were plenty of fruit trees and water and game. There still are, even today. Also it was close to a field of special rocks, the kind of rocks you carve into primitive tools (sticks with a rock tied to them). Many rocks were found carved, but discarded because the carver blew it.
now, that region is called Aden even today, by locals. You can see it on maps.
