But there is something in existence in the location we believe a black hole exists, and given the mathematics surrounding observed astrological events and objects, there is little doubt as to the existence of black holes.
Direct observational evidence is impossible because light cannot escape a black hole(ironically proving them to exist). We just see an invisible 'hole' in spacetime.

We can see the matter that is falling into a black hole. They are called quasars.
