It's not a question... but a starting hypothesis... Consider something true
and then either shows a contradiction or not (if you find a contradiction
starting from the assumption that the hypothesis is true... then you've
disproved the hypothesis).

But as usual you cannot grasp basic logic. You have to past the hypothesis
to discuss it and eventually find or not a contradiction... stopping at the
hypothesis, will let you stuck... you can discuss it for an infinite time
it won't help.
