text: Well, as far as a line of reasoning, you could start with existence itself.  We all agree that the universe exists. Astronomers have observed that the universe is organized into a system of galaxies, clusters of galaxies, and super clusters of clusters of galaxies.  \n\nIf you're open to the possibility of a higher power, you'd have to ask if this power is responsible for the universe.  If you answer yes, then your next question is, is the universe an act of creation, or is it an accident?  Either way, your next question is "why?"  This line of questioning will bring you either to the biblical explanation of god, or the scientific explanation of god.
