Could there be a galaxy that has developed closer than andromeda that we can’t see just because the light hasn’t reached us yet? How are all of these galaxies around us so old yet evenly distributed? Is there a blank spot in space that galaxies may exist but the light hasn’t reached us?

If they’re older, we’ll probably never see them because they’re moving away from us faster than the light can reach us. If they’re younger we’ve probably already seen them, they just haven’t formed yet, and this can take millions/billions of years, so again, probably won’t see them. At least, that’s been my understanding of it all.
