I'm an independent myself but, I have to say that scientific facts are scientific facts. That doesn't mean that creationism is the only answer (obviously they are dead wrong in several areas) and it doesn't mean that the big bang theory is the only answer either. Even though the big bang theory is the most plausible current explanation for what happened 13-14 billion years ago you're right in that it hasn't been completely proven. Also, let's say for the sake of arguement that the big bang theory was proven 100%. That doesn't mean that there is no God. It doesn't even mean that that's when the universe actually started. Even according to the BBT there was a single blob of ultra dense material before the big bang and it has also been theorized that we have a big bang followed by an implosion followed by yet another big bang over and over again throughout eternal time. I can't ever comprehend why the two sides keep arguing that it has to be one or the other. Why can't there be a God, the big bang theory, and evolution, all at the same time? Even as far as evolution goes, there can be a God and he can even be responsible for humankind to some degree as it has never been proven that every living thing's ultimate ancestor is an Amoeba (but even if it was it still doesn't mean there is no God). But, evolution, at least to some degree, is a scientifically proven fact. It's hard to take anyone seriously when they deny absolute facts.
Subwannabe-
You are dead spot on, and the answer is it doesn't. Despite their medieval foolishness, the Catholic Church, for example, has no trouble with evolution and the Big Bang came out of a monk, and most mainstream faiths have no trouble with scientific explanations of how things happen (interesting,the RC initially resisted evolution, but not for what people might think, it was because they were afraid of what did in fact happen, social darwinism, where the powerful and well off argued that their wealth or power was due to them being 'socially evolved' and those power 'unevolved', which is crapola (though sadly it is being revived in recent decades, where those poor or down on their luck are 'undeserving poor' while the rich are somehow 'different', 'better' and so forth, or worse, the religious right with their 'prosperity gospel' (like the evangelical preacher I caught on tv, saying Jesus was having a good spot of fun with his statement about a rich man going to heaven being harder then putting a camel through the eye of a needle).
The people who have trouble with the big bang or evolution are not rational people, they are people who read an almost 3000 year old tale in Genesis (that has two versions that are different in two different areas of Genesis) and believe it to be literal truth, they are people who believe what a not all that bright 16th century Bishop presented as fact, it is people who read the words but don't understand the meaning (Joseph Campbell put it best, he said fundamentalists walk into a restaurant, see steak on the menu and eat the menu).
The universe is an incredible place, there are things like entanglement where two particles once together can be split apart, and if you interact with one particle that causes a quantum state change, the second particle, no matter how far away (light years, doesn't matter), changes quantum state mirroring its twin,simultaneously.
