All serious studies of comparative religion and culture demonstrate how religous beliefs affect individual behavior and the ultimate success of a civilization. Few will deny that the Calvinist view of man’s ultimate destiny was a huge factor in the historic individual capitalist achievements that created great wealth and aspirations. Nor can it be denied that an equally firmly held belief in a caste system leads to non productive stagnation whatever other talents and latent abilities such believers may have. Humans are theonly species known to have an advanced capacity for mysticism. That mysticism is expressed even in athiests and agnostics in a myriad of ways. How it is expressed tells much about an individual and his or her behavior beyond the rituals.

a fine answer, but not relevant to the question I asked you; what makes belief in polytheism less credible than in montheism...?
