It depends on your story more than anything, and generally speaking, D&D tries to give its players simple power fantasies. If you wanted, you could run a more grounded game with more mortal protagonists...but I'd recommend against using D&D for that. (Maybe some variant of E6.)
Most of those "classical heroes" were blatantly superhumans in some way or another... those were almost the superhero stories of their day.

I don't think someone needs to be the son of Zeus or the son of Krypton to be a hero.

(I'd recommend against using D&D, flat out, but that's just me.)
