Science vs religion

I know, I haven't been posting in a while. My excuse is homework, coupled with the fact I haven't had access to a computer where I knew how to use spell check (Which, if you consider the spelling errors I have with spell check, would make a post practically impossible to read) over christmas vacation.
At school, in history class, I've been learning about the John Scopes case, in which a science teacher named John Scopes was tried for teaching the theory of evolution. The simple case of whether or not he had broken a small, local law spiraled into a huge debate over the age-old question of science versus religion. And the defense, by the end, resorted to more or less trying to disprove much of the old testament. Given that the defense lawyer was a practicing christian.
I believe in evolution, but this kind of questioned my faith.
This doubt was deepened when, in science, we learned started our unit on the universe, which, if you believe it (Like I  do) pretty much discounts the whole creation story. But the thing that disturbed me most of all was the fact that, apparently, the earth was going to be burnt to a crisp slowly and painfully. Why would god put us on a planet that was doomed from the start?
The universe unit also exposed how small earth is compared to the whole world. I have never heard of anything in the bible saying we were the biggest thing in the universe, but it is still pretty demeaning.
To be honest , lately I've been doubting religion in general. It seems as though the word of god is somehow fighting things that can easily be proven true. And, although in some cases religion and science can agree with or even back up each other, they clash so much that it seems hard to hold onto christianity.
But the thing is, it only really disagrees with the old testament, which is also the part which has God go out killing the Hebrews' enemies (A very un-Godlike thing to do) and says the homosexuality is a sin. I can't find a single passage in the new testament where science would disagree with it (Except possibly Revelations, which is most likely in code anyways). And that is where true ideals of Christianity come out.
I'm not saying the old testament is a lie. Jesus does agree with most of it, doesn't he? But in the fine details arguments spring up.
But, whether or not he created the earth in seven days, god is out there. Why else would people who are resuscitated describe an after life? If matter and energy can't be created or destroyed, who made all this? Why is there life on the earth in the first place? These are the true questions that prove fatih.
