NASA’s Webb telescope spotted an active supermassive black hole that existed 570 million years after the Big Bang. That’s really early.
What I mean is the smaller the window the less you see of the bigger picture. Say I look at the Hubble Deep Field image. I see a lot of galaxies, however that field of view only encompasses mere fraction of what is observable. So sure, the further you look out, the further you look back, yet the further you look out the less you see the overall picture.
But you are also looking at a universe that was much more compact then, with galaxies and structures bunched much closer together than now. It may be a narrow field of vision compared to the current size of the universe, but that narrow field of vision has also expanded in the subsequent 13+ billion years.
