Acceptance of a particular creation story, and of accounts of miracles vouchsafed by it, is called the faith of the believer. Faith is biologically understandable as a Darwinian device for survival and increased reproduction. It is forged by the success of the tribe, the tribe is united by it when competing with other tribes, and it can be a key to success within the tribe for those members most effective in manipulating the faith to gain internal support.
