ELI5: What Exactly is Atlantis? Why did it Get Destroyed and is there Any Evidence of it?

Just a little curious. I always have and still do believe it's fake, but I over heard someone talking about it saying it was real and I would like to know a bit about what people think of it.

It's nothing more than a story Plato made up to illustrate a point. It never existed as a real place, and until fairly recently nobody seriously thought that it did. 

There's absolutely no reason to believe it was based on any real place, but that doesn't stop people from trying to link it to this or that extinct civilization.  This is simply bad pseudohistory, and it is never supported by any actual evidence.
