I believe in God, but I also believe what science tells us.  I really don't see why so many people think the two are incompatible; the Universe may have been created by the Big Bang, humans may have evolved from apes, (both of which I believe) but that doesn't mean that God isn't the cause of these events.  God could well have used the Big Bang to create the Universe, and guided the steps of evolution.  Just because something has a scientific explanation doesn't automatically mean that it wasn't caused by God. It's quite likely that God needs to play by the rules of his Universe, meaning that he needs to find a scientifically compatible way of doing things.  A miracle is still a miracle, even if it is scientifically possible.
