What evidence is there to support that Atlantis existed?

Not too much, but there is a case to be made for global floods of the supposedly neolithic era/Ice Age.

From the information presented in the CC video at ~1:00 is the single best piece of evidence in favour of Atlantis:

A). The Nile river flooded predictably
B). Myths tend to be based on local events
C). Therefore Egyptian myths should portray flooding as beneficial and non-cataclysmic

However, it is FROM Egypt that the myth of Atlantis comes from - indicating that the Nile couldn't have been the cause of such a myth, but rather an exceptionally cataclysmic flood.

In spite of this, I would still hold that Atlantis is probably not located in the Atlantic Ocean. At the very least, there should be SOME cities under the ocean - if not a substantial number.

Pretty good evidence of the existence of civilizations predating Plato which could be his inspiration for Atlantis but none from 12,000 BC. Also pretty good evidence for the existence of prehistorical peoples that were destroyed or at least forced to relocate because of natural disasters and flooding but none that could be rivals to Greece, most prehistoric peoples didn't even build cities. None of these existed beyond the pillars of Hercules anyway.

Pretty good evidence for civilizations that existed beyond the pillars of Hercules but they weren't in contact with Greece, weren't civilizations that could be rivals to Greece anyway, weren't large enough to fit the description of Atlantis, and weren't prehistoric

So pick your poison I guess.

Maybe? Who knows.

As in they fled from Atlantis or the great flood was a metaphor for them?

every major civilization is situated near seal level, primarily, that was even more true in the past. At the end of the last ice age sea levels rose something like 120 feet and every major civilization was underwater. 15,000 years later the only remnant of that history is the legend of Atlantis.
