I really am amused of the way you, having no proof of anything, start pointing and saying that people are idiots because they think something else?
Anyway, I do believe in the Big Bang, however I don't think it explains of how it all came out. It's quite abstract to think that everything was created of nothingness, but then, it the end it all comes to the idea that something came out of nothing. Because there should be something that is first, right? Then maybe that 'nothing' is something. But what? God? I try not to consider the idea of "God", if there was that powerful being, why would It go through Big Bang and so on to create a chaotic universe? Why would It create it in the first place if It leaves the rest to chance or does It control everything. And then again, why are we rational if It still controls us?
The only thing I can think of are elemental theories that could explain nothing.
