Since learning about when the Sahara was lush and green and became the great desert due to a cyclic earth wobble that moved all the rains away, I’ve been fascinated by several questions. Who lived there, where did they come from and where did they go? The last question is answered by assuming they fled to the Nile area and jump started Egypt’s civilization. So that raises the basic question of how high a civilization did they have? Anyone else interested? I’ll confess to superficial knowledge based on You Tube videos on the topic of the Green Sahara. I just can’t help suspecting that this area is a missing link.
