Question: How did the universe begin?

I want your personal theory on this. Did god create the universe? Was there something else. Has it always been here? State which side you're taking (i.e. scientific, theological etc.) and try to support it as best you can. Lets try to not turn this into a debate. If you want to comment on someone elses theory, fine, but try to keep this thread from turning into an all-out debate about religion.

So, what do you think?
