Only a very tiny part of it is computable (this is provable if you accept the Church Turing thesis).But it's questionable whether it "exists".Does it kick back?

Of course "discover" begs the question.
If so, it exists by any reasonable definition (including Stephen's)
Two beings with different laws of physics in different universes could invent the game of rock, paper, scissors. Does that mean the game exists? Did it exist before they invented it? Does the continuum exist?
