The theory that black holes existed has been proven.
You seem to be completely unaware that a theory is an explanation that best fits the facts that we have. It can make predictions and can be tested. There was no 'theory of black holes'. But there was the theory of general relativity which predicted black holes.
Facts can be proved true or false. Theories are either revised or discarded.
