Since galaxies were discovered, scientists have been searching for their structure and ways of creation. The universe, after big bang, goes to lower density and the density of a black hole is extremely high, like protons (1018 kg/m3). So, although black holes are create from stars, we can conclude that some of the nuclei of black holes could create from big bang moment. Taking into account that a black hole, like stars, has a surrounding area and the more compact center, we should think about the creation of this center from big bang moment.
Therefore, the creation of galaxies, that we know must have the central black hole, could be start from initial time of big bang, as we see the James Webb telescope have found some galaxies with the age of about our universe.
