@durrrrr: i'd like to see valid "proof" for the Big Bang. From what I know its still a theory.
Probably the best known proof is Hubble's Law. Speaking in simple words, Edwin Hubble discovered that galaxies are moving away from each other - Universe is expanding. And if Universe is expanding, if you know the formula, which can calculate how fast do galaxies move away from us, you can calculate when all the Universe was in a single point.
