You are correct. Science doesn't prove things came about by chance. Scientists, whose starting axiom is that there is no God, are only able to interpret evidence in a way that suggests there is no God. The thing nobody talks about is that these theories (The Big Bang and Evolution) keep being modified because they don't match the evidence.

I know that this is a slight simplification of the Big Bang Theory, but it is utter nonsense to think that there was nothing and nothing happened and then suddenly there was everything. Also believing that there was an explosion, but gasses coalesced enough that gravity overcame the forces that cause gases to expand. There is so much evidence disproving these theories and showing them to be nonsensical, but the brilliant scientists don't want to believe that God is so much smarter than them and that they owe Him homage.
