Where did the energy come from to create the big bang?

Don't you understand, laws of physics didn't exist until after the big dud, er..uh, I mean, big bang. Then, after that, the laws suddenly came into being all by themselves. It sounds strange, I know. But you've got to forget everything you were taught in high school because once you get into college they show you the real science they don't show everyone else. Trust me.
