Personally, I don't see why religion and science have to be diametrically opposed. To me, science tells us the HOW about the Universe. Religion tells us the WHY about the Universe. God created the Universe? Cool. Makes sense, there had to be before the Big Bang. Maybe God sneezed. Or pushed a domino over. Whatever. He started stuff. Six days? Could have felt like it to God. We may have been made in his image, but I'm damn sure God isn't human. He's got to be some being that exists beyond the three dimensions that we exist in. And so on and so forth.
I think it comes down to the fact that the nature of science, by general definition, is that it's based in change -- accepting new ideas, re-defining present knowledge, finding new explanations and testing theories (and then replacing old ones once we have better ones). The nature of religion is essentially inert -- steeped in the preservation of history as it is written, unaccepting of any new information which may change previously accepted historical-based 'facts'.
It's only natural that the two are going to butt heads when one is based in preservation and the other is essentially founded in the practice of the opposite. That's not to say that I think people can't pick and choose what suits them from either camp and share beliefs from the two different systems -- arguments only really start (as always) when you get into extremists from either side. Personally, I'm comfortable in the middle of the road, saying that both camps make good points, but neither is perfect or, ultimately, 100% correct. Now, if I say that to a scientist, he would likely agree and and welcome new information as to how we can make the system more accurate through testing and research. If I said that to a religious person, they would find my saying their system is imperfect to be an attack on their belief because it's saying their historical records are wrong, which threatens to break down their whole system. I think this difference in reaction is where we ultimately wind up getting in trouble.
(Edit: And Bill Nye just made reference to the difference above that I just mentioned. Thank you, Bill.)
