We don't know that Jesus turned water into wine truly. There are a lot of explanations for the things that Jesus did, but all in all, we don't know if he actually did them or not. We can prove he existed from a lot of different means, but specific events like turning water into wine could be purely fabricated, or just misunderstood.
What I was trying to say before is not to judge scientists from your owned warped view of their beliefs. You do not know these people individually, so you can't automatically stereotype them as god hating atheists. We cannot explain the original cause for the universe, and that's why the scientists are searching for the Higgs Boson particle, primarily known as the "God Particle". Just because they don't believe in the creation story doesn't mean they can't believe in God. As I said before, the whole bible is filled with contradictions, and to follow every belief from it would be ridiculous.
I believe in God, I'm not going to avoid that point, but I don't believe that it's supposed to be told in a literal sense. It's my firm belief that it is a purely metaphorical lesson on how you should lead you life, and whether God is the cause behind these rules or not, it is a good thing.
I don't really get what you're trying to say in your last sentence. You don't need to know science, nor do you need to know anything that you learn in upper schools, but it is still useful in a lot of circumstances. Where would be without science after all? I would go into what the world would be like without religion, but I'd probably end up ranting about "holy wars" and stuff.
