10 Fan Theories For Upcoming Movies (That We Hope Are True)

10. The Eternals Were Created By The Infinity Stones

The Eternals is slated to be the Marvel Cinematic Universe's second movie of 2020, and since these characters are newcomers in this universe, it's unclear how their origin story will be handled.

What we do know - courtesy of the cast relaying information to EW - is that the MCU's Eternals will be "a race of immortal aliens sent to Earth by the Celestials to protect humankind from the Deviants". We've met the Celestials in the MCU before (Ego is a Celestial, and we also saw Eson the Searcher in Guardians of the Galaxy) so we know that they're among the most powerful beings in the universe, and the general idea is that they created the Eternals long ago. But how?

One fan theory has suggested that the Eternals will be brought into existence via the power of the Infinity Stones. We already know that the Stones are capable of creating powerful life forms (the Mind Stone gave Scarlet Witch her abilities), and we also know that the Celestials have possessed the Stones at one point in time: Eson is seen wielding the Power Stone, for example.

Phase 4 is a new beginning for the MCU, but it's not unreasonable to expect callbacks and references to the earlier Phases, since that's one of the most entertaining things about keeping up with these movies. Since we've literally seen a Celestial use an Infinity Stone before, this theory just makes too much sense, and it would be a relatively simple and efficient way to explain why the Eternals are so powerful.
