I've collected some of the more plausible theories. Enjoy:

Mettaton is a robot.

Mettaton is a ghost.

[Monster] is just a product of Frisk's young imagination.

Toby Fox has a human soul.

Sans was dead the whole time.

Asgore has a human soul. (I mean yes, like six of them)

Chara is actually a human.

Papyrus knows Sans.
