If it helps, the determinism of the observable universe in the cases of physics and chemistry might be an elaborate illusion of averages on the quantum level.

If it helps, the determinism of the observable universe in the cases of physics and chemistry might be an elaborate illusion of averages on the quantum level. In essence, we can't see the quantum interaction of particles and their superpositions, we can only see the average produced by a large number of these actions and reactions. This gives a small, but nonetheless interesting, hole from which randomness can leak into the apparent deterministic systems we see. I recently walked a similar road when thinking about human behavior as a product of genetics and outside inputs. For me, the angst was the view that "free will" might be fictional, and I had built a lot of my personal ethics onto that pillar. But it was curiosity that led me out of that nihilistic moment when I thought about the loophole above.
