@Frank Apisa,
It is possible that they see the human brain, and the processes supporting it, as too complex to allow for meaningless happenstance and that a belief in gods provides a useful organisational tool for building and maintaining society.
A guess that there are no gods is a derivative of the guess that there are. The functioning structures in which the guess that there are no gods can arise are hardly likely in the absence of the guess that there are gods.
A guess that there are no gods in a society dependent on the guess that there are gods might very easily be suspected of a solipsism superficially convenient to the guesser. Such a convenience vanishes when everybody guesses that there are no gods.
Refusing to guess either way ought to result in the concept of gods not being a content of consciousness except in the sense of the sociological, military and economic consequences of the preponderance of one or other of the guesses in a particular social organisation.
Those who refuse to guess or guess that there are no gods are then required to offer an alternative to the consequences of the guess that there are gods, or that there is a God. Failure in that respect behooves them to cogitate on the subject within the confines of their own infantile noddle.
