You know, how GAIA is treated as a goddess by the Nora (I mean, making things out of light, literally created everything, so they're not wrong. The genius of how magic and science and sci-fi and primitive life and a bit of cyberpunk and the idea of the apocalypse and ragnarok and genesis were seamlessly combined i can't stop gushing.)
If ever someone else comes upon their holograms or even just their photos, or if Aloy ever shares and spreads their stories, this is how I imagine the Zero Dawn Pantheon will look like.
So the myths go like this: At first, this world was occupied only by the sire of the Metal Devil, feeding on barren lands and drying oceans, but Gaia endured and eventually triumphed with the help of her own children. However, sometime in the chaos, the Metal Devil successfully blasted Apollo till only her essence is left (said essence which will one day choose her champion in Nora Tribe member Araman as her medium to return, by giving him a boon of her knowledge and instructing him to go to Minerva's spire to plant a seed that will one day be instrumental in her resurrection) and planted a corruptive essence of his in Hades. So the All-Mother and her court gives birth to the world, Eleuthia assisting mothers in childbirth, Artemis shepherding wild life so it doesn't devour everything else, Hephaestus forging the tools each need to thrive, Apollo's essence providing knowledge, and Minerva how to use it.
And a myth isn't a myth if it's so linear and clear-cut, so in some versions, it says that the gods, as Minerva as their leader, gathered together for Hephaestus to forge the quintessential essence of themselves, someone who will oversee everything simultaneously to keep the perpetual balance, and came Gaia (I'd imagine this is the Oseram's favourite version, if they had favourite versions of religion). In some versions though, it's the other way around, where Minerva and the others are Gaia's children. As it so happens, in this version, Aloy is considered less of a god's champion/Anointed One and more of a goddess herself, most art even depicting Artemis in her fashion, with red hair and a spear, stalking a machine. Otherwise, Artemis is a male of dark hair and clean shaven hair, while Aloy is an immortal champion bridging the mortals and the gods, essentially a demigod by being born a god but raised as human and probably a patron of heroism/soldiers and assistance or something. Metal Devil is how the essence of all evil and taint is referred to, but especially brazen people or extremely blasphemous ones, may whisper Ted Faro.
Sometimes, Apollo is an active lover of many men and women, sometimes she's a modest woman who's really more interested in acquiring and making knowledge and just so happens to talk to a lot of people to do her duty. Sometimes Hades is a kind, just, and inevitable king who had the unfortunate chance of being corrupted by the Metal Devil, sometimes he's constantly faced with disappointment from his family because of his blatant lust.
There is a name: Elisabet. Could be Gaia, could be Minerva, and though rarely, can also be Aloy. Only thing that doesn't change is that she's a Mother. Gaia's or Aloy's or both. You know how it is. There are many debates.
Carja, of course, choose their patron god as Apollo (who take the form of Samina). Ban-uk has Artemis (I imagine Aluki in particular is fascinated with the stories of how Artemis once took the form of a young maiden and had a band of other young maidens they bring for ETERNAL HUNT!). The Nora are very smug about being right about the All-Mother -for the most part. Oseram aren't the most religious but they have preference of Hephaestus. Eleuthia is the patron of expecting fathers and male family members -they cannot start or stop the act of birthing, nor do it in place of their partners, but they can still be a part of the act by assisting, as it was believed Eleuthia did for his mother. Demeter is, of course, patron of farmers, also herbalist and anyone who puts plants on their plates. Hades is basically patron of people like Nil, who believe that everyone is equal in death -there's also little Travis statues in graves. Generals, kings, organizers, planners, traders, pray for wisdom from Minerva.
The only one programmed with a visual form is Gaia, but eventually, as learning AI who can learn compassion (or, already cares, since they're all initially aspects of Gaia before gaining minds of their own) they just use the forms of their Alpha creators.
Also, none of the AIs whatsoever understand that humans treat them as gods. They are, after all, still just learning how to identify sarcasm. So sometimes, people may ask for a story about, say Apollo, and the question may be phrased that they'd think it's referring to the greek god Apollo.
So, yeah, religion is basically just partly miscommunication and misunderstanding but if you think about it not really.
Also, Carja may start wearing head scarves, as an 'expression of their faith' as Apollo explained their hijab. And also Apollo is basically a reincarnation of the internet.
