I haven't read all of the posts here so I'm sorry if I'm repeating something that has been discussed already. And I haven't really studied much to do with anything discussed here, so I'm just asking a question that I've always been curious about but have never researched or discussed with people.

I was just wondering what you guys think about how "everything" started. I mean before the planets, before the big bang, before ANYTHING. What was there before that? Is there a scientific theory that explains this?
