Proof of Impossible.

There is something impossible.
Suppose we are given a task of finding something impossible.
There are two possibilities:-
1. We succeed in finding something impossible.
2. We are unable to find anything impossible.

In the first case we have found something impossible.
The second case cannot exist as it is self-contradicting because if we do not find anything impossible then, at least, the task of finding impossible is impossible.
