The Lost City Of Atlantis

For years people have been trying to understand how the city of Atlantis disappeared. Some say that it is underwater, a big Tsunami destroyed it.  Another theory I read about was how Atlantis could control the skies and waters. This would mean if they have control of the skies, Aliens were there guiding them along...what would this mean about the city? Did it have the ability to disappear with out trace? Another dimension?

The theory I believe most is Plato's description. Plato wrote that there were bronze gleaming islands that fell from the sky and landed in water....Atlantis was not a  stationary island but in fact Crafts...According to Plato, the "islands" disappeared in one night! They disappeared with alot of fire and alot of smoke....How would actual, physical islands be able to do this? They can't, it was the crafts who the people thought were islands taking off.  Atlantis did not sink but in fact lifted up to the skies.
