there is in fact evidence in support for the Big Bang, like the fact that our universe is still expanding. Faith, by definition, is belief without evidence. So no, atheists who follow the Big Bang theory are not basing their knowledge of it on faith. As for the burden of proof, the Big Bang doesn't disprove anything. Theists make the [i]positive[/i] claim that there is a god. I, as an atheist, reject your claim. Why is this concept to hard to understand? Anyways, I'd rather follow what scientific theories, which are always changing and developing based on new information, than what an ancient book written 5,000-2,000 years old proposes.
