Religious belief that the universe is the handiwork of an all-powerful being is not subject to refutation. This sort of reliance on faith may itself have an evolutionary basis. There has been talk of a “god gene”: the idea of an early advantage in the struggle for survival for those endowed with a belief in a hidden patrimony that gives order, purpose and meaning to the universe we experience.
