Because the other notions of proof do not "meet that high standard", you
even find that if you present a long, careful, mathematical, deductively
valid proof to someone whoo follows one of the other notions of proof,
you'll find that he jusn't believe it, because in his experience, long,
detailed proofs often come to wrong conclusions.
Perhaps this is eveidence that they are really other notions of proof.
