There is no free will because who, what and where you are conditions you to make a certain choice every single time, and there is no will external to all that what you are and you experienced so far.
It's kinda related to the multiverse theory, where every choice or chance creates a new version of reality and if you had made another choice it wouldn't be YOU.
At least that's what they argue. I also think of it this way.
TIL about vacuum decay. Thanks for sending me on that wiki trip.
