I tried reading "Mere Christianity" by CS Lewis on the strong recommendation of a friend. Its core claim is that while many of our ideals of morality shift over time, some are absolute and transcend place and time, and therefore they must have been created by something outside of the universe. That claim occupies only the first few pages, and from there he attempts to further conclude that not only is there something, it is specifically the Christian god.
