The CMB is the oldest light in the universe. It’s too red shifted for Webb to see. Webb can’t find galaxies older than the CMB.

Aren’t these new oldest galaxies too advanced to be formed 300 mya?

No as they did form. We still don’t know a lot about galaxy formation. Now that we can see very young galaxies we can refine our models to better explain how galaxies form and evolve.

My thinkin as well, there is a huge piece of the puzzle we don't see yet.

I got the strange feeling something similar like the quantum/relativity theory will be found that will explain better the expansion of the universe (incl. dark matter), what we call "the big bang", and the findings of Webb.
