>>714317091 (OP)The fact that we cannot change the past or see the future proves that free will is an illusion.
Everything that has happened was meant to happen by the fact that it happened and you cannot go back to change it.
We can only "predict" what will happen or what we will do in the future but it will always be the present until an action is taken which then creates an irreversible past.
We live in an eternal present and everything that has happened or will happen has already been set by the ever existing present.
