Didn't we know black holes 100% exist 20 yrs ago because of the orbits of the stars around the centre of the galaxy and before that because of quasars?

Which, yeah, isn't quite the same thing, cause you could imagine that if GR was slightly wrong, you could have something slightly different at the center than a True Singularity.
