Is it not possible that the chimpanzees are responding to some feeling like awe? A feeling generated by the mystery of water; water that seems alive, always rushing past yet never going, always the same yet ever different.

Only when our prehistoric ancestors developed language would it have been possible to discuss such internal feelings and create a shared religion.
