2 years too late for the debate lol but thought I'd add the Bible has many references to God choosing to forget (or not remember). Probably where our saying "Forgive and forget" comes from. If he is an all powerful God, surely it would be within his power to know everything but choose to forget it. Also even if knows what we will do in the future, maybe because if free will, he lets us do what we choose rather than jumping in and trying to change the outcome ?

Just some thins to consider, have a nice day
