What makes one automatically assume when he sees a house a carpenter, when one sees a bridge a bridge builder, when one sees an ant hill an ant architect, when one sees a bee hive a bee builder....yet at the prospect of a universe that operates under natural laws and where the mechanisms of its management are in perfect mesh...how is it at this the mind has abandoned itself to this madness of disbelief in a Maker?
