> But as of a little more than a week ago I’m finally convinced that black holes exist, just as General Relativity suggests.

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?

Well, we had good reason to believe that there were things with approximately their mass in approximately their area that emitted approximately 0 light to us. 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.
