I have the same crack on my Series 0, it's been there for years, and it's because I accidentally skipped it against a brick wall.
If your screen was coming off OP I'd think you'd have a case (glue giving out). But this is clearly an impact. Just because you can't recall when it happened doesn't mean it didn't. Our hands move all over the place day to day. It sucks, but you hit it against something at some point without realizing it.
