Doesn't it seem to take much more faith to believe that this universe just came into being instead of being created by a divine power and that something so complex as a cell could be formed at random? And that these complex cells turned into complex organs which turned into complex systems which turned into complex and functioning organisms also by random interaction of cells. Even if there was some primitive self-replicating ribozyme, how could it replicate in such a path as to form an organism. What could direct it in such a way that it would "evolve" into an organism other than God. So you see it is not unreasonable to believe in God; in fact it is more logical than not believing in God. No one can "prove" that God exists, just as no one can prove that he does not exist. The difference is that one can provide evidence for his existence in intelligent design, whereas there is no evidence that God does not exist.
