You are free to criticize the legitimacy of religious beliefs, but science will not help you. Science cannot disprove what it does not accept or examine (namely, supernatural events). Science simply says that a natural explanation exists. Whether that explanation is "true", science cannot say. If gravity is really caused by an invisible flying spaghetti monster pulling everything with his noodly appendages, science will never see it. It cannot. Science refuses supernatural explanations.
I am not saying that popularity makes supernatural beliefs correct. I'm saying it makes them important. The concept that science is one way, but not the only way, people choose to understand the world is important. Whether science is "true", no one can say. Untestable, supernatural phenomena are just that: untestable. It could be that the flying spaghetti monster really controls everything in universe. All we can know is that if he/she/it does, he/she/it does it in such a way that natural explanations still work. There's no way to actually test the theory of a supernatural spaghetti monster. The distinction is subtle, but I think it's important.
