In barbaric and prehistoric times, before primitive man invented religion and prayed to gods for intercessions, man was isolated and alone, facing an uncertain and terrifying world that worked by its own logic. Would the sun rise every day? Would winter fade and spring follow in its stead? Would there be fish to catch, prey to hunt, rain for water and crops, bountiful harvests, cures for disease, pregnancy and babies, victory in war? Would the tribe flourish? Tribes were like advertisers today, looking for certainties and prosperity in a hostile world.
