What books, movies, plays, poems, places, or people have had the greatest influences on on shaping and guiding your beliefs? For the agnostics and athiests, please feel free to contribute those things which have firmed your own convictions. For me, the natural world and the barely glimpsed universe have been the major influence. I'm a firm believer in the theory of evolution and various theories concerning star and planet formation. Yet, looking around me, it's too amazing that it would all be just a huge series of accidental coincidences.
