I’ve been reading some books and speculative fiction that a ice free, more temperate Antarctica may have been Atlantis and some catastrophe happened approximately 12,000 years ago.

I think what happened 12000 years ago was the poles shifted. Antarctica could have been at the equator then. We don’t know... it would also help explain how people got to North America so early if they didn’t have to go across the entire Atlantic, but actually hopped from Africa to Antarctica to South America for instance.

The Carolina Bays were formed about that time.

SunkenCiv posted a discussion about a large impact in Greenland, and subsequent “splash” impacts as a result.

All about 10,400 years ago.

Too remote. Has to be close enough to Athens to allow Atlantis to attack.
