Forms of lights and our capture of it creates our “vision”. The longer the distance it took the light to travel from the objects to our telescope, the more time it takes. By the time it is finally captured, we are watching an outdated light!

An outdated galaxy.

I hope that’s what you meant.

What I heard it now they think galaxies started forming pretty early after the big bang.

There's also the hypothesis of angular diameter turnaround: that at a sufficient distance, more distant objects would appear larger rather than smaller, because they subsumed a larger fraction of the universe at the time.

This has not been observed by JWST so far as I'm aware.

Memorialised in an xkcd comic, of course (Explain version linked here): <https://www.explainxkcd.com/wiki/index.php/2622:_Angular_Dia...>
