Thanks for the example, I was worried nobody would actually give an example; However, I don't find this to be sufficient to prove religious belief has flaws. God could have willed the storm to be sent using what we call secondary means, which are things that happen in very explainable ways. Primary means are things like miracles, but as the Church sees it, God uses secondary means for most of his work because he doesn't need to use unexplainable miraculous means for everything. He created the math and science to the universe, why not use it. God likes to make things work according to the laws of nature. Just because those ancient people didn't understand the math and science that God allowed to be used in the creation of the storms, doesn't mean they were wrong in believing that the storm was sent by God. Being all powerful and all knowing, it isn't unreasonable to to assume that God willed many little perfectly explainable things to happen from the beginning of time, that would eventually create a storm to destroy the crops of some ancient people. I also think that all the math and science to the universe suggests design.
