From what I understand, black holes are incredibly massive. They formed systems that added to the collective mass(gravity), which in turn led to more and more collected mass(stars/dust/what not). Over billions of years it's now the galaxy we know. Our galaxy is in a group of galaxies that will evolve and attract until they merge, growing further.

True, it's a little counterintuitive thinking more mass equals smaller radius
