You can't argue against religious people, if you do, they will always leave feeling they've won the argument. Sure, while they're throwing stuff at you like quotes from Genesis and Romans to back up their claims, you'll be required to have be extremely familiar with biochemistry, physics, quantum physics, string theory, biology, and a plethora of other sciences the average religion person has no knowledge of, but happily refutes using circular logic from the Bible.
Don't bother, no matter how convincing you are, it will be shot down by their belief that all science is only out to disprove God and you only believe it because Satan tells you to.
