Well, it's either that or the Oscillating Universe (which I think is the one where you believe the universe has always existed and there was no beginning, there has been no change). There's another one in which the universe expands and collapses, expands and collapses, etc. I believe in the Big Bang, but only because a better theory hasn't really been created (at least one I know of). When you look at it from a scientific scale, it makes sense, but if you just think that it was a huge explosion, then it doesn't.
