True, but just based on what we know it still seems likely. Feige said the movie could cover thousands of years of human history, if I recall correctly, and yet certain hints (like Thanos’ father), point to some of the Eternals being from space.
This is what he said.
Eternals are one group, but we like the idea of introducing an ensemble, doing an ensemble movie from the start, as opposed to building up as we did with the first
Avengers. More like
Guardians, not tonally, but in terms of introducing a new group of people. You were asking about ’60s, and ’70s before. Jack Kirby did an immense, amazing epic with
Eternals that spans tens of thousands of years, and that’s also something we haven’t really done, which is why that among many other things post-
Endgame, we find appealing.”
Doesn't say human history.
They might well go that route. They could say they were humans that were taken to another world or just be aliens though.
Earth is getting packed with heroes now. Having a race of super being living amoung us that we are not aware of begs a lot of questions. What have they been doing through all the thanos stuff etc...
I really don't know how they are going to do it. Hopefully we get some answers after ffh is released.
