The responses above are all solid and well reasoned, however, they are also a bit of a dodge.
While what people are saying is factually true, they are glossing over the opposing view point.
Here's the problem:
While it is true that evolution, abiogenisis and big bang are all independant concepts and do not rely on one another for support (the big bang could be false, evolution would still be true) they all have something in common - they violate Christian Fundamentalist Creation Mythology.
The more you learn about the various topics, the more you'll discover that (surprise surprise) the people who were writing about these things 2000+ years ago didn't have all the facts.
What astounds me is not that the Christian Fundamentalists deny evolution, but that they don't deny the Earth's orbit. After all, the same thinking that dictates their evolution denial is just as valid as it was pre-Galelaeo when everything in the Universe revolved around the Earth.
So, should you choose to go down the road of science, you'll find that pro-magic, anti-history, anti-logic, anti-evidence beliefs put out by the Fundamentalists contradict what can be shown to be true.
In this way, learning about Evolution will show you that the Fundamentalists are profoundly wrong about a great many things, including Big Bang, Abiogenesis, History, Anthropology, Linguistics, Mathematics, well, pretty much anything that using information from any book other than the one they like
