In ages past, humanity found plenty of incentive to believe in things we now laugh about. Gods lived in volcanoes, and would grow angry enough at times to spew hell upon surrounding communities. Demons, powerful enough to change the landscape, would make the earth tremble as they attempted to force their way out from underneath. All kinds of beings appeared in dreams to offer torment or to grant anything one might wish. Snake oil served as the medicine to cure all ills. We think of our forefathers as ignorant, but, do we really understand our modern world so much better than they did theirs?
