Of course there is a God. How else can humans explain the inexplicable. Long ago there were many gods because we needed explanations for the sun, the moon, the harvest, the rain, war, love, death, children, craziness, sanity, etc. As science advanced, most of these inexplicables were finally understood and those specific gods were no longer needed so they fell by the wayside. Science still hasn't found explanations for everything, so some people must still have a God to believe in so they don't have to worry about the things they have no answers for.
