I can't remember who wrote it, I'm thinking it's John Lechte... But anyway, I've commonly heard Christians and other assorted religious people refer to "God" as everywhere and everything, but Lechte pointed out that if God is "everything", then he is nothing at all.... To be everything means that you are nothing, because you have no identity, identity makes the individual as does difference. If you are everything there is no difference, no individualism and therefore no identity leading to nothing.
Totally off topic, but I found it interesting and that is all that matters.
As for Science vs. Christianity.
Christians cannot provide evidence that a god existed, although there is some proof that a man named Jesus survived, and that he was quite popular amoungst the people... But then again Paris Hilton is popular with some people so there's no accounting for taste.
Meanwhile, Science hasn't really got anything better, it has theories. The theories of the big bang, the theories that the materials for life came from simple molecules, or from outer space. To date, I don't think any of these theories have been proven, correct me if I am wrong.
People revert to religion because of that age old question, a la Artistotle. What is the meaning of life? Aristotle believed it was based on the senses, and that if you could sense something (touch, smell, etc) then it was real, but he then reasoned that even if it is there, and can be sensed, is it real? Can any of you prove that you exist? If you can prove you exist, then perhaps you've found the meaning of life. The whole, obeying god so that one can go to heaven and live forever and eat chocolate cake and such is perhaps a fall back on not being able to work out the meaning of life. Humans don't want to believe that after we die, there is nothing. It would be hypocritical for a Christian to believe in heaven, but not believe in Creationism.
Science however provides answers for a lot of the biblical stories. Whether or not you believe in science is a different story. I once had a scripture teacher tell me that science proves nothing. 5 minutes later he was showing us a video, of an experiment proving that the grand canion was created by the flooding (a la Noah), and is not a result fo millions of years of erosion and sedimentation. I find it highly hypocritical that Creationists don't believe that modern science can prove the bible wrong, yet they use "science" to prove the bible right?
