How would we know that? I mean, humans are implied to be very, very powerful, especially the magically adept ones (like the ones that created the Barrier in the first place). Who says they can't attack with bones and Gaster blasters?

Sans could be a human who is using magic to appear as a skeleton (from the knee down), anyways. My personal headcanon is that W.D. Gaster is Sans' father and that Gaster used to be a rebel human before he was shattered across time and space (hence "the man who speaks in hands"). Gaster also could've experimented on Sans to grant him the abilities that you see him use in the genocide run battle.
