Alright. But most of the rest of us don't share your premises or conclusions, and free will exists perfectly comfortably as a phenomenon in plenty of atheist philosophies, including mine. That you don't believe it fits in other peoples' philosophies isn't very meaningful, because you generally don't tend to understand (or try to understand) other peoples' philosophies anyway.
Free will fits perfectly comfortably in atheist philosophies that allow for supernatural forces to exist, sure. There are plenty of people in the world who don't believe in God but do believe in souls and spirits and whatnot. Like, you want to talk about not understanding or trying to understand, the moment I bring up a supernatural concept, I'm immediately bombarded with tired, banal arguments people heard Richard Dawkins make once that don't actually apply to what I'm saying. I would love for someone to take on the conception of free will I presented rather than attempt to disprove God instead, but here we are.
The premises my argument is built on here are shared by the majority of western civilization though. Not because they are Christian premises, but because they are the basic assumptions of science: that the natural world exists, that it has an order that can be explained, than a scenario with identical circumstances will result in an identical outcome, that this information can be used to predict or repeat outcomes. Add to that a basis in empiricism, the idea that valid knowledge is found through experience. A scientific framework does not allow for free will as a natural force. Free will defies order, free choices can't be explained, you can't count on them to be repeated. If one believes that science is the proper perspective for understanding the natural world, one cannot categorize free will as a natural force.
I make a good deal of effort understanding people's philosophies here. You honestly might be an exception to that rule, because I don't know you've ever spoken to me about what you actually think. You seem largely content to just pick at my words looking for something to dispute, which is fun and I appreciate, but hardly puts you in a position to complain if I don't know your personal philosophy.
