with how light works and the constant expansion of what we term the “observable universe” why don’t we constantly see new stars appearing in the night sky as the observable part expands and stars/galaxies light reaches us for the first time?
The night sky has stayed relatively the same (accounting for changing postions over time, stella phenom, supernovas etc.) for all of humans written history.

Something like 99% of the stars you see in the night sky are in a small patch around us within the Milky Way. Beyond that would be brighter stars still within the Milky Way. We cannot see stars alone outside of our own galaxy.
The nearest major galaxy to us is the Andromeda galaxy with an estimated 1 trillion stars and approximately 2.5 million lightyears away yet you can barely just see this massive space structure (natural structure, I’m not a crazy person saying it was made by beings) with the naked eye due to this huge distance.
If you can barely see an object made of 1 trillion stars you’ve no hope of seeing the individual stars within it. It’s like seeing a grain of sand a few feet away and hoping you can see the atoms that make it.
Now the edge of the observable universe is around 46.5 billion lightyears away. That is 18,600 times further away from us than Andromeda.
If we can barely see Andromeda, a space structure made of 1 trillions stars, how would we have any hope of seeing a star that is 18,600 times further away.
I hope this has explained it easily enough for you.
I think most people tend to forget or just don’t know just how incredibly huge space is. Here is a video to help show the sheer size of space, I love to watch it at least once a year by reallifelore
