From [1] and [2] we read that the CMB was created around 380 million years after the Big Bang, and that hydrogen atoms were created at the same time. The original article above [3] says that this galaxy was created when the universe was about 300 million years old. These seem to be in conflict; am I misunderstanding something, or is there really a conflict there?
