From what I know, it’s a rather sorted, convoluted, and incestuous affair.
Much depends upon the invention of written language 5–6 thousand years ago, allowing recorded history to confirm the first belief in Gods. Most assume that the Gods existed before that, albeit surviving in purely spoken form, or depicted as animal spirits in primitive artwork. This is assumption, but the care given to certain animal burials suggests great reverence.
It’s difficult to sum up all cultures into one consensus. Comparing the Americas, Europe, African, Eastern and Middle Eastern notions of Gods leads us to innumerable accounts. But the most consistent story lines between them all seem to evolve out of observing the basic elements of the universe. Not necessarily worshiping them, but more of an acknowledgment.
Interesting that observation is the very first step in the scientific method. An argument could be made that religion was born out of science. Then, science born again out of religions desire to explain the wonders of Gods creation. It’s slippery.
The most commonly accepted first observation of existence are the Primordial Forces, which were not Gods, but the creator of Gods. Chaos (void) being the first, and from it came Gaia (earth), Eros (love/heaven), and Tartaros (lowest hell). As these Primordial Forces grow, they produce children, mate with them, thereby birthing the Gods and Heros such as Zeuss, Achillies, Hades, Giants, Cyclops, and the Titans.
This Creation of Gods scenario is played out among many religions bringing us the Gods of Humanity within space/time. Eastern demigods, Zoroastrian moon God… brought to us by Chaos.
But others speak of a Prime Mover, or Echo, or a Vortex from another dimension outside of space/time. Brahman, Jehovah, are most commonly accredited as being responsible for speaking Chaos into existence from a realm independent from our physical reality. They are reported as capable of dwelling in both realms simultaneously, and are considered fundamental requirements for the continued existence of our physical realm.
I don’t have it all worked out and probably never will. But it’s very entertaining and fascinating for me to see the evolution of Gods. Who knows…? Certainly not I.
or maybe…
