I believe that free will exists but I don't quite understand why. It would make more sense to me if true free will didn't exist. I for one don't believe in anything supernatural like the soul, spirits, etc. So if we are a sum of the atoms that we are made of, then I assume that if an exact copy was made that this copy would be identical in every concivable way. Even in the way it thought. Now our neurological network is also comprised of atoms, meaning that the way in which electrical impulses are fired should be predictable. If I take all these assumtions to be correct I arrive at the conclusion that the decisions we make and even our thoughts are predetirmened and that if there was an infinitly fast computer that knew where every single particle in the universe was located, it would be able to calculate everyone's thoughts. Surely I missed something or am I just bonkers?
