reading about IRAS 10214+4724, a proto galaxy, found on the edges of the observable universe, has got me thinking and i am kinda stuck in a thought.
say this galaxy is 200,000 years after the big bang,, and lets pretend there isnt expansion (it doesnt really matter in this case). lets assume this is the first galaxy in the observabke universe.
SO lets say we train our tellescopes on this object that is 15 billion lights years away.. and watch it for 1 billion years, changing from a proto galaxy to a full fledge one.
Assuming it isnt moving towards us or away.. in a billion years it should still be 15 billion light years years away but now the edge of time or the big bang has moved back a billion years. so the edge of the observable universe is now like 16 billion years away
My question is what would you see if you focused on the spot where the first galaxies are forming.. would you see IRAS 10214+4724 as it is being formed near the time fo teh big bang 16 billions years ago and see the same galaxy at 15 billion light years away as it is a billion years older?

SOrry it is such a messy thought.. hope it is understandable.
to shorten.. if we discover the first galaxy ever being formed and watch it for 1 billion years getting bigger.. why cant we look back near the big bang and see the first galaxy ever formed

My gut says we wouldnt be able to see the same galaxy forming.. maybe a different one... but it is really starting to bother me and maybe one of you can tell me what i am missing.

It's like being in a dark room when the lights go out. First you can see things closer, and then you can see things farther out, as your eyes adjust.

In 1 billion years, we'll have watched the galaxy build up. As well, we'll be able to see a billion years further out, so we'll see new galaxies building up.

So, in the dark, you watch your hand. As time goes by, you'll be able to see the lamp too.

not really what i was asking so i will answer for myself.
the light cone of the galaxy 1 billion years old is blocked by the galaxy itself preventing us from seeing the same galaxy at an earlier stage. so as teh uninverse gets older and we see more and more stars.. we lose more information about the past.

so looking at 200m lightyears from the beginning of time.. we could see another galaxy form but not the same galaxy as the light from that galaxy forming is now blocked by the light from the galaxy at it's present age

edit:
a reread of your comment, i better understand what you are saying and see that i am just reiterating it in a different way.. thanks for the reply.
