Someone is trying to create a Facebook account using your contact information. Something that happens to me hourly, because people just cannot stop assuming sinan@yahoo.com is their email address.
Don't confirm. Usually, the emails have a link where you can tell Facebook you are not trying to open an account or reset your password. Carefully inspect it before following it.
Ten years ago, I got fed up enough to write a post. It hasn't let up ;-)
