Actually, Science does not disprove God -- according to the Islamic "bible" -- the Qur'an, a lot of the things we've discovered by science actually happen.
Theres a description of the Big Bang, life coming from water, and even *gasp* evolution (Although its changed a bit, to say that humans are special and were not made via evolution, but everything else is. However, we are still today looking for "the missing link", so this still stands)
Also -- the Qur'an was kept as pure as possible. There was an intense screening process of writing down the remembered stories -- cross checking them multiple times. It was about 5-10 years after Muhammid's death (he's the one who said the Qur'an, BTW. He was also illiterate, and considered the Qur'an his only miracle. If you read it, its amazingly eloquent), but there were still "first-generation" people around. After they got it down, they ordered everything else to be destroyed.
Maybe this isn't christianity, but Muslims believe that Chirstians/Jews both recieved the same exact message, but it became twisted over time.
(I'm athiest, BTW. But I'm not going to go around being ignorant and/or arrogent)
