Is there proof that Atlantis exists?

As far as orthodox, or documented science goes, the Jury is still out. there are speculations of extensions of Flood legends, and actual Greek Islands, but.. very little evidence at least recognized by mainline archaeologists, etc. if such a civilization was in existence as long as Plato claimed, surely some archaeological remnants would have survived- and perhaps as he implied there were survivors who settled elsewhere, a sort of Atlantean diaspora- as the Donovan song maintains- wouldn:t there be some Greek-style artifacts as vases, urns, coins- certainly they had money- and coins will, under proper circumstances, last indefinitely- there is something called an Atlantean script, usually in Grey and White or light-contrasting blue and grey. this has appeared in comic books and as a wallpaper design in, as you might have guessed, the Atlantis Night club in Coney Island. no one knows if the script is authentic or is merely some abstract modern-art design loosely based on Greek Writing. My Dad noticed it at the night club and thought it was mere ( Abstract art) called also (Squiggles). no Atlantean artifacts of the usual sort have yet surfaced.
