why PROOF

Why do we need to prove that things are true?

when we have a very very simple and obvious hypothesis, such as 1+1 = 2, why we need to prove it?

Some things seem true, but aren't. Sometimes, the proof technique turns out to be useful somewhere else, even if the result isn't that useful.
