[Marvel] Why is there no Apocalypse like threat for human race?

In comics we are told that Apocalypse is not first of his kind and that apparently Celestials always choose an individual from species who would be a threat to said species and push them to evolve. We see that even Eternals had their Apocalypse. With that in mind, why doesn’t humanity have their own Apocalypse, but mutants do? Does it also mean that on countless other planets there are alien “Apocalypses” running around and wrecking stuff?
