How Early Did Galaxies Form?

We are seeing early galaxies. You couldn't see these galaxies with the hubble. These things are very, far, very faint. And james webb itself can even just barely pick out that they exist. We see these smudges that we think are galaxies, meaning, you know, many, many stars. So what we're seeing are real objects we can't resolve like stars with planets around them. But we can tell that there are galaxies out there in the very early universe and that's exactly what we're trying to understand. How quickly did these galaxies form? How big were they? How bright were they? And does that agree with our model for how the universe evolved
