Atlantis

I was reading this article online about Devas, Elements and Fairie, and according to what I was reading we humans used to live side by side with them, before Atlantis sank. According to this article, humans became so greedy and starte using them for war, etc, and this was one of the causes why this continent dissapear along with them.

Perhaps this makes sense, humans are and always been greedy. I was wondering if anyone knows anything else about this.
