> literally nothing in the observed universe does

There are many things on earth that don't exist anywhere else in the universe (as far as we know). Life is one of them. Just think how unfathomably complex human brains are compared to what's out there in space.

Just because something doesn't exist anywhere in the universe doesn't mean that humans can't create it (or humans can't create a machine that creates something that doesn't exist anywhere else) even if it might seem unimaginably complex.
