So if it took 13B years for the light to reach earth, doesn't that mean it was in that location 13B years ago? That would seem to be impossible since, it would not be possible for any two objects to be 13B light years apart 13B years ago.

I can't figure that one out.
There's been some thirteen gigayears of expansion of the spacetime, too. And frankly, anything that ancient is expected to look subtly weird somehow, too. Analysis of spectral features is probably going to lead to a number of "hmm, that's really fucking odd" moments.
