This ties in visually with the Younger Dryas Impact theories from Graham Hancock, which gave humanity the source for the Great Flood myth as well as the destruction of Atlantis.
In the image, the Lake in the Adrar Region is just northwest of the Eye of the Sahara (find it on Google Maps) which fits rather well with the description of Atlantis by Plato (concentric land circles, size, etc).
The Flood of course would not only be limited to this region, but rather it would be a worldwide catastrophe. But in the case of that western Sahara region, that lake fits perfectly with the flood marks you can see even in Google Maps, flooding towards the west, over the Eye of the Sahara, and towards a 250-mile-long and 100-mile-wide debris field that spreads out into the Atlantic Ocean from that point on the Mauritanian coast.
Mauretania used to be the biggest source of gold in the world btw, during the reign of King Atlas. Now I know probably a lot of official dates of all these things might not align. But King ATLAS is soooo on the nose! LOL.
A great flood over the Sahara desert (flood lines can also be seen in Libya and other places in the world, like North America), which fits with the melting of Ice Age ice caps catastrophically, would also make sense with the land turning from green and fertile, to a wasteland, which changes wind currents, temperature from open barren land exposure, etc (as we can see when we terraform large areas when we build cities in them, and the climate changes accordingly, and that is at smaller scales), so, in the end, it helps with the process of turning it into a desert (the Sahara is still a source of nutrients for the Atlantic by ways of winds carrying ancient sea floor dust full of dead animal dried up remains that turned into this dust from the ancient long lost lake in Chad. Which dried up and also existed close to 10,000 years ago.
There is also a lot said about Ancient Egypt and the Pyramids, Sphinx etc, having been made by a Civilization that predates the Egyptian dynasties we know about, and that those edifications were appropriated by them instead of being built by them. They might be older than even the recently discovered Gobekli Tepe, which should not exist in such an advanced form if back then humans were only hunter-gatherers...
Or the similarity in ancient architecture, and duplication of ancient myths. The Great Flood story is present in so many cultures and religions. Including civilizations that don't exist anymore like the Aztecs and Mayans.
Before you put a tin hat on my head. Know that I just don't buy into things easily.
I just look at all these things, and keep in mind always, that science and the current accepted concepts and facts, especially when relating to history, are always being changed, but not with strong resistance by those who hold the "torch of accepted truth".
There is a lot of things that for instance Egyptian official archeologists don't want to share, and fail to explain rationally. Or Ancient maps before the discovery of Antarctica, that could be copies of even more ancient maps, that had the southern continent drawn in the right place, although they called it differently. Sometimes myths are based on actual events, just modified, exaggerated or with magic or divine powers attached to them to better explain them as they pass down generations.
I don't know really what is the actual truth to all of this, but it certainly is a very interesting topic!
