Perfect. Then Earth human limitations have no bearing whatsoever on what the game mechanics for any of the classes should be.For the same reason that it has nothing to do with elf, dwarf, giant, warforged, halfling or any other race. Race has nothing to do with class. Hell, they even took Bladesingers away from elves and let anyone be one now.
And yes, it is because they said so. If they had said in the rules that humans in D&D have the magical ability to fly, they would be bog standard Earth humans in every way except that some time in their past they gained the ability to fly. D&D doesn't give humans any supernatural abilities, though, so they do not have them.
If we give D&D fighters the ability to leap chasms, fly, or slice mountains in half, then human D&D fighters would simply be Earth-similar humans with those abilities.
This is fine with me. I, personally, do not care one way or the other whether we label them as humans, faerunians, or whatever.
All I want is that, in the same way we give "human" casters the ability to do spells despite a complete lack of real-world Earth precedent, we can give other classes physical abilities with no real-world precedent.
Almost like it's a game where the characters are not from, or of the real world.
