As Jules Verne's thinly disguised travelogue 20,000 Leagues Under The Sea firmly established, Atlantis is under the Atlantic Ocean, not Africa. Sheesh. Doesn't anyone read books any more?
In 10000 BC sea levels were some 60 meters lower. The place to look for seafaring civilizations is on the ancient coastline of that period, not on land. Having access to free food (fish, clams, whales, seaweed) and generally more moderate temperatures makes it the most ideal place to build and prosper (until the ocean rises that is). We're only just beginning to discover what's down there.
Unfortunately for Atlantis the ocean was rising much faster than it is now. Maybe the concentric circle structures were their failed attempt to hold it off. If Atlantis is allegory, we have yet to learn its lessons.
Of interest might be The Archaeology of Europe's Drowned Landscapes (Springer Press, published 2020). It is free on Amazon, Apple Books, Google Books and about 1000 pages long. I'm just diving in to it.
