"The creation myth was the essential bond that held the tribe together. It provided its believers with a unique identity, commanded their fidelity, strengthened order, vouchsafed law, encouraged valor and sacrifice, and offered meaning to the cycles of life and death. No tribe could survive long without the meaning of its existence defined by a creation story. The option was to weaken, dissolve, and die." ~ E.O. Wilson
