Your science cannot predict a coin flip.
Neither can your God.
God only knows.
In a million years science may be able to predict coin flips. Keep working at it. There are a lot of currently out of control variables. A big one is the consciousness of the coin flipper. No good model for that right now. We don't have a clue. Our best scientist Stuart Hameroff, says the best test for consciousness is to ask them if they are awake.
