Proving that would be quite hard ;)

  Not necessarily - proving there are infinite primes is easy. It could be hard or impossible, or it could be easy or moderately hard but either way no one's figured it out yet. (And yes it's sometimes possible to prove that something can't be proved.)

    1. It's a major unsolved problem in mathematics - definitely not "easy"! 2. In this case it hasn't been proved that it can't be proved.
