Can you think of a better name for your civilization, though?
Officially calling them just as "Humanity" is so bland there's a reason why no sci-fi does that. It just doesn't work.

Versus calling it something long, convoluted, and trite within the genre like the "Holy Republican Consortium of Terra-Earth"? No, I don't think so.

I see it no different than the Avars calling themselves the Avars because they're all Avars. It's a self-given identity among a people who are not totally aware of the entire breadth of the galaxy, but know it's larger than they assumed given the Precursors.

It's not to say they refer to themselves as such on a regular basis and would most likely refer to other synonyms, Earth, or Sol. But that's just as bad.
