A lost ancient civilization capable of advanced seafaring and astronomy likely existed.

“I do think that there was a lost civilization. I don't think it was as technologically advanced as a lot of the other Atlantis guys do, but I do think that there was one that was good at seafaring and good at astronomy.”

The theory of Atlantis is a fictional thought experiment used by Plato, not a historical account of a real lost civilization.

“The entire dialogues that start with Plato demonstrate and they say explicitly this is a thought experiment. It's about a war between Atlantis and Athens and it's designed to test or to demonstrate how the ideal city from the Republic would act in war.”

Atlantis was a real civilization that matches the geography of the Richat structure and was destroyed during the Younger Dryas period.

“it's by far at the eye of the Sahara, also known as the Richat structure, matches more than a dozen similarities to what Plato had described the lost city of Atlantis.”

Atlantis likely originated from historical records of a localized flood or village disappearance rather than a high-tech lost society.

“My probably the most I would air into any credence towards that is a story that has been changed and handed down through time of some village disappearing underneath, you know, whether it was waters rising uh from end of the last glacial period or a flood from a river”
