The original story of the lost island of Atlantis comes to us from two Socratic dialogues called Timaeus and Critias, both written about 360 BCE by the Greek philosopher Plato.
Solon had been to Egypt where priests had compared Egypt and Athens and talked about the gods and legends of both lands. One such Egyptian story was about Atlantis.
Atlantis was arranged in concentric rings of alternating water and land. The soil was rich, said Critias, the engineers technically accomplished, the architecture extravagant with baths, harbor installations, and barracks
A small but just city (an Ur-Athens) triumphs over a mighty aggressor (Atlantis). The story also features a cultural war between wealth and modesty, between a maritime and an agrarian society, and between an engineering science and a spiritual force.

Atlantis as a concentric-ringed island in the Atlantic which sank under the sea is almost certainly a fiction based on some ancient political realities.

Maybe...

"The Law of One" material said there was a Great War
in the Days of Atlantis between the Sons of Light and
the Sons of Dark. Their weapons caused large Earth Changes.
Last of Atlantis sunk into the Ocean around 9,000 B.C.

I`m familiar with that, this might be interesting as well.

I believe the entire Sahara Desert Area used to be underwater.
Great Earth Changes happened long ago.
It may have been the last pole shift that formed the Sahara.
