I'm going to spilt the difference here in that pantheons of gods were probably inspired, or reflections of early tribal groups - the elder (Zeus, Odin , or whomever) being the wisest, biggest beard and male (as males were more likely to survive into older age) the anti-elder (Hades, Loki, etc) being someone close to them, but who resented the respect that the group had for the elder, and various other tribal archetypes (including crone, mother and maiden) which encapsulate a number of virtues of humanity.
If the elder had a son then naturally they would be expected to become everything their father was, if not more (Hercules)
This early group of tribal characters echoed over and over again probably gave rise to one of the first inherited human memories.
Monotheism raised the importance of the male gender and reduced the importance of the female, thus number of the pantheon drop to two or three.
Everything is a reiteration of a reiteration. The idea that hell is beneath our comes from Hades, the idea god has a beard comes from both Greek and north European pantheons, the idea that God's son will return at the end of the world, is the same in Egyption mythology as it is norse legend.
If whatever belief makes you want to behave in a beneficial manner towards society or even nature, yeah, great, that fine- let's do it.
However the moment its used to annex countries or make people believe that they are better than other people , that's just uncool.
Ah, people say to me - ah, should you be celebrating Christmas if you feel like that? - to which my answer is, Hey - Christians stole the winter Solstice, damn straight I'm celebrating Christmas.
