"I just wish that someone could tell me what happened before the Big Bang"

There is no "before the Big Bang." God sitting there setting off a Big Bang would be him breaking yet another law of physics, the one that says that time is an integral function of the universe and, like everything else in it, started with the Big Bang. Still, it's up to him I suppose. It's God's gig, not mine. Just don't ask me to believe it, that's all!
