    Well, observations of the Milky Way's black hole require that something with the mass of millions of stars exist within an area of space smaller than a few dozen AU. The only plausible candidate for such a massive and dense object is a black hole.

    Observations on all galaxies seem to lead to the same conclusion (massive black hole at center).
