Time for a little side trip. Since free will ultimately goes back to the laws of nature, in some way it must be relevant that people think there is such a thing as a beginning (unless you believe it’s turtle all the way down). The point, I suppose, is that no one has a clue how the universe came into being or if it even came into being or if beginning/nobeginning makes any sense. “Free will” may be a concept that has no meaning in which case I might as well go back to listening to music.
Sabine Hossenfelder is a theoretical physicist working in Germany. She makes YouTube videos about physics and music videos. All are worth watching if you have any interest in science. Here is her video about some of the ways the universe may have started. I favor unicorns. By the way, Sabine Hossenfelder does not believe in free will.
