Pool Table
Imagine a pool table with 9 balls either scattered around or racked at their original place while the cue ball is ready to be hit by a player. If the theories based on classical physics are true and complete, then the future courses of all balls on the table is determined right after the cue ball is hit (The Big Bang). The only condition required to support the statement above is that neither the table nor the balls would be disturbed during the event. Efforts have been made in the past to develop computer programs and robots to compete with humans based on classical physics.
If we expand this thought to the entire universe including human brains which are made by various elementary particles, the development of our universe should follow its determined course after the big ban happened years ago. Keeping in mind that the universe we are living in is an enclosed one (limited space-time) and no evidences have been found that our universe is interacting with or disturbed by other universes at this moment. How about parallel-universe theory? I have to think about it.

My problem with the pool table image is that it only describes a purely theoretical concept, which may or may not have anything to do with the real world. The virtual pool table is a software program, a deterministic procedure based on physical laws abstracted from real-world physics. It is not a real pool table, where I doubt any human or machine champion pool-player could repeat the same shot twice. All you end up proving with your example is that deterministic pool tables are deterministic, and that a deterministic theory of physics describes a deterministic model of the universe. But what of the real universe that resists being perfectly described by classical physics?
