There is some evidence that Adam and Eve may have been created in central Ethiopia, and that their descendants remained nude for centuries before "God gave them clothes" to wear. And that came primarily because as they moved slowly northward, they needed clothing for changing weather and climate conditions. The oldest farming villages were in Palestine; the oldest city is Jericho. And recent DNA evidence links all human beings to one woman in equatorial Africa.
