Did Atlantis really exist?

Yes it did truly exist.

One of the things that makes atlantis really cool is at one point in time all land masses was connected and altantis is the one place that proved that all people were one at that time for traces of all races where found there in one place

I am not sure about that. There's a lot of books written about that and movie as well. Others say that it is myth but I don't know which one to believe.

I believe that it did exist at some point. I noticed that there's a similarity in the words Atlantis and Atlanta. They call Atlanta ATL, and some people also call it Magic City. That city is located pretty close to the Bermuda Triangle where all kinds of weird stuff happens. I live in Florida so that's kind of close by to there too. I've also heard of the devil's triangle which is located somewhere in Asia or something. Wherever Atlantis supposedly was, now it's said to be back underwater in the sea somewhere.
