When you look at the properties of gods you will soon notice that the more gods you have in a pantheon the more fallable they are, the more gods, the more human the gods. The stories of the polytheistic religions like Hinduism, Greek, Roman, and Norse Mythology are quite different from the monotheistic. The Norse (which I know most about) clearly states that the gods are greater than man, but they are not infallible (there is no objective evil, the most "evil" god is Loke and he is just a trickster) they are mortal, but can grow very old because they eat from the tree of life (comparable to greek and roman ambrosia) the god Balder is in fact killed via the trickery of his uncle Loke. When did people decide that they needed a god that had inhuman abilites and motives?
