There were civilizations LONG before 10,000 years ago in S.A.
Look at google maps, and zoom in. You can clearly see the former waterways that were created all over the southern part of the continent.
They look very ancient, but are clearly visible- and do not look natural.
Look for the “Eye of Africa’ - ANOTHER structure that scientists cannot explain as anything other than man-made, and if you zoom out it looks as if the whole area was washed away in a flood. (Atlantis?)
The Eye of Africa is a natural formation and millions of years old. There’s a YouTube nitwit who pushes the BS about it being Plato’s Atlantis. Watch his face, no blink rate, crazed stare all the time, unsupported claims and assertions, zero evidence.
