Science can't prove such a thing! In reality science does not prove anything. Science observes facts, proposes theories to explain those facts and performs experiments to validate the theories.No-where-man said:Yes,but if you accidentally prove that God didn't create the universe,than he doesn't exist.Also,what would create God,metaphysical God only exists in human imagination,metaphysics is wrong approach,meaning God is wrong hypothesis.There is no outside the universe.
If an experiment shows that the theory is not valid, scientists try to improve the theory or substitute it for a new one. If the experiment confirms the theory, this does not prove it, it merely makes it more likely.
If after a great number of experiments all of them verify the theory, the likelihood increases, but it never reaches 1.
Even if scientists where able to show that the Big Bang has likelihood near 1, this would not prove the Big Bang hypothesis and even less the non participation of God. God could have created the Big Bang and all the laws of physics, chemistry and biology so that after 8 billion years after the Big Bang a small planet orbiting a class G star would form and 4.5 billion years after that event evolution (created by God) would allow that intelligent beings would be discussing in this forum.
I don't claim that God exits, I only say that we cannot postulate his/her nonexistence.
