Numenorë - Atlantis?

I'm pretty sure there has been a topic about this before, but I still make my own.

So, isn't Numenorë's story pretty much alike Atlantis's?

They both were great lands in an ocean, and if I remember right, it's said that Atlantis was destroyed by a god, Zeus. At least in some version of story.

Well, Eru was also some kind of god, and he destroyed Numenorë. And they both, Numenorë and Atlantis, sank into the bottom of the ocean. There is much same in these stories, so could it be that Tolkien got his idea of Numenorë from Atlantis?

Blah, really bad topic of course, because I'm so bad in writing english.
