Of course, there is one big question that would need to be sufficiently answered: if mutants descended from the Eternals in one form or another, then how come they haven’t been seen or heard from yet? Assuming the MCU’s Celestials ran their experiments millions of years ago like in the comics, then that means by now, a decent, if not abundant portion of the population should carry the X-gene. So you’d think that at some point over the MCU’s first 23 movies, even if the X-Men hadn’t formed yet, mutants as a whole would have at least been mentioned.
