May I just offer something:
Neither evolution nor the Big Bang particularly contradict the existence of God.
The Big Bang has nothing to do with the
ultimate creation of the universe (probably the most common misconception I've ever come across), while it does explain the state of the early universe, and does makes some prediction we have exactly and preciously zero information as to what the universe was like before expansion started (the start of the Big Bang.)
Before the Plank Epoch (
Planck epoch - Wikipedia, the free encyclopedia) things simply cease to make sense, although we do believe that there was a universe before the Big Bang, just not in a way we particularly understand. Unless you believe something like this: (
Big Bounce - Wikipedia, the free encyclopedia)
As for evolution, there's no reason that couldn't have been 'overseen' by God, if that's your sort of thing.
Anyway, may I pose some questions?
-The Big Bang theory goes something like this: "We see space expanding, therefor it was smaller in the past, therefor it was very small in the very early universe." From that we simply do the relevant mathematics and such to attempt to define things about our early universe. The Big Bang is usually the name given to the start of expansion. If the Big Bang were not to have occurred, that means you are (albeit indirectly) refuting the expansion of space.
What alternatives could you offer to what we observe?
