In mythology, sure, but is it in the movies? I can’t remember.
I know that in Norse mythology, Valhalla is just a place in Asgard, but the movies specifically refer to it as the Asgardian afterlife - their concept of heaven. It’s obvious that the MCU gods believe in something greater than themselves.
“As the supreme being within the Multiverse,[9] the One-Above-All is omnipotent[citation needed] (and presents himself as all-powerful),[3] omnipresent,[citation needed] and omniscient,[citation needed] and is above all cosmic powers and abstract entities, even the Living Tribunal.”
It’s better to say godhood is hereditary, but not genetic. Loki, Thor, and Hel inherited godhood from their father, just like they could inherit the throne of Asgard.
That’s the problem, you keep watching this movies with zero context. Without their history and character development all you are getting is the big super hero fight scenes, and if you are not into that there is nothing there for you. Try watching the first few in order, at least until the first Avengers movie.
That’s a good question. Loki ruled Asgard (in Odin’s guise) apparently well enough that no one rebelled. He at least has the chops to rule. And we’ll see if there’s any opposition to Valkyrie becoming the Queen. She’s Asgardian, but no hereditary right to the throne.
The best method would be to watch them in the sequence they were released.
But if that’s too much, any of the films that introduce the protagonist don’t need much prior knowledge. So, Iron Man (2008), Thor (2011), Captain America: The First Avenger (2011), Guardians of the Galaxy (2014), Ant-Man (2015), Doctor Strange (2016), Black Panther (2018), Captain Marvel (2019).
Also, two on schedule to be released this year will be starting new stories: Shang-Chi and the Legend of the Ten Rings (2021), Eternals (2021).
“Gods” in the Marvel continuity are basically really powerful aliens that are worshipped. If people worshipped Superman, he’d fit right in to the concept of a god in Marvel comics (that would be a weird Marvel/DC crossover though). They could even talk about Krypton like human legends spoke of Asgard and Olympus. And DC has flirted with the idea too.
More than flirted. Kirby’s “New Gods” are literally just powerful aliens. Some of them aren’t even on Superman’s power level. The difference between Orion and Superman is pretty much that Orion thinks of himself as a New God, and Superman thinks of himself as a super-hero.
And back at Marvel, Jack Kirby also created the very similar Eternals, who were just super-powered human offshoots who were mistaken for the Olympian gods (who they randomly just happen to strongly resemble and have very similar names to). And in Marvel, the Olympian gods actually exist, but the Eternals are about as powerful as they are. The difference between Athena the Olympian and Thena the Eternal is just down to the fact that one of them thinks of themselves as a god and the other doesn’t.
WAG: particularly back in the '60s and '70s, most of Marvel’s writers were either Christian or Jewish, and they probably didn’t want to be writing comic books in which they postulated that the Asgardians (or the Eternals, or whoever) were actual deities.
I meant “flirted with the idea of Superman as a god” but yes, Kirby definitely did the “superheroes as gods/gods as superheroes” thing both at Marvel and DC.
Good writers let the characters say what’s what. Asgardians call themselves gods. Tony Stark, Jane Foster, and other scientists in the MCU call them aliens (more properly, “extra-dimensional beings” - which is a good definition of the God of the Bible, as well) . If a viewer has an inclination to differentiate the two, Marvel/Disney is happy to let them make that decision for themselves without alienating the majority of their audience that self identifies as monotheistic.
My WAG was that it originated with Thor, and Asgard first appeared in Marvel Comics in October 1962 in Journey into Mystery#85. That’s when they show Asgard as being a futuristic city, more of a high-tech alien land than a spiritual realm. (Note that Thor himself was introduced 2 issues earlier, in August of that year.) Thor ended up dominating that series until they just renamed it The Mighty Thor. But I suspect that it was Thor that started the whole thing in the early 60s.
Thor Odinson… you have betrayed the express command of your king. Through your arrogance and stupidity, you’ve opened these peaceful realms and innocent lives to the horror and desolation of war! You are unworthy of these realms, you’re unworthy of your title, you’re unworthy… of the loved ones you have betrayed! I now take from you your power! In the name of my father and his father before, I, Odin Allfather, cast you out!
From the very beginning of the medium in the 1930s, comic book writers (overwhelmingly secular Jews) have never been squeamish about tapping pagan mythology for heroes, and they almost always presented them as actual deities.
