well i got up to about the beginning of the 3rd page, so forgive me if i missed something, but heres my take on it, if you look at this purely scientific (putting aside the thought of a soul or other supernatural force) then there is absolutely no chance.

with all the same amount of force and exactly all the same variables, dice will land in exactly the same way, everyone wants to say that they have control over there decisions, this is completely untrue.

you feel you have control over yourself with perception but in all honesty every decision you make is based on a connection in your brain of some type that took a decision and made it based on what your expirience has been and what your current situation is. you feel that as a decision, and if it all happend exactly the same way again with exactly the same past and present, then you will do exactly the same.

As far as people earlier talking about a parallel universe, not possible.... not that I dont believe there could be a univarse out there with all of that planets scoped subjects being exactly the same, but think about this, if you have to travel to get there, then do it have exactly the same position as our universe?
