I don't think anybody "believes" in the Big Bang. It's just tons upon tons of evidence that lead to the conclusion. And besides even if we do discover one day that the Big Bang is indeed absolute fact, the next big question would be "what made it?"
For all we know we could literally be in a rabbit hole of nesting universes, each with their own completely independent laws of physics.
