We don't understand God. We portray "God" in many different ways. To me it's only logical that a God exists. It wouldn't make sense to come from nothing. To me it's really as simple as that. Religion is a great way to make people comfortable, but it's when we start to express it and get into arguments things get all jumbled and everyone hates each other.
Prayer gives me the peace of mind that I want. It's usually comforting and it's nice to have someone to talk to when you're in need.
But other than that, I can say that some bible passages to me seem very far fetched and I doubt how they could actually take place. I find myself someone who needs both science and religion in my life. I believe everything that science has been able to prove, but I also believe the concept that religion explains it in. (It's really hard to explain, I don't quite understand why I think like this but it's just the way I am)
Eg. How the earth was formed: I believe that the earth was created from the big bang, and not that God just popped it there and started to make it in seven days. He is more like the delicate hands of a sculptor which sculpted a universe, and let it do it's thing. He guided it when it needed to be guided and did add some of his own creations to it. (First life forms, humans etc.) - (Sorry Evolution hasn't actually been proved fully)
I just thought I would put out what I feel about this world.

R Version:
I believe in both science and religion, and they are both responsible for the creation of the universe.
