It's important to note that our understanding of the early universe is based on the available observational data and theoretical models. While our observations have provided valuable insights into the early stages of the universe, there are still many unanswered questions, particularly regarding the exact conditions and events that occurred in the moments immediately following the Big Bang.
If there have been any recent discoveries related to the formation or existence of galaxies prior to the Big Bang, I would not be aware of them. It's always a good idea to consult the latest scientific literature or news from reputable sources to get the most up-to-date information on scientific discoveries and research.
