The first thing to happen after the Big Bang was the emergence of the fundamental forces, followed by the various fundamental particles, then nuclei, all within the span of a few minutes. It stays like this for almost 400,000 years before it cools enough to allow for unionized atoms, which then slowly collapse over several hundred million years into the initial filamentous structure of stars and galaxies, which was pretty much the same as it is today. Whether or not you consider the Big Bang itself as the ultimate deterministic starting point, or if it’s somewhere else in the sequence is up to you. The Big Bang set the starting conditions for the universe, but the galaxies and larger structures of the universe were not present until much later.
