If you think the Nation of Gods and Earth (5 Percenters) are really out there, I don’t think they can top this one. There is a movement called Kemetic Sciences. They believe that the ancient Kemetians (Egyptians) were black Africans descended from Space aliens. The Kemetians are supposed to have started civilization and it’s been covered up Europeans.

Here is a lecture on Kemetic Science.

The Coptic name for Egypt is Kemet, but these people have twisted Egyptian history. Why this type of historical revisionism is even taken serious is beyond me.
