Discussion: What does it take to prove that we are not living in a computer simulation?

The question seems very simple; it is clear that we live with free will. The best scientists, philosophers, and physicists have debated this question for years without unequivocal conclusions.
The simulation theory will fall if you can locate an event, nature show, behavior, emotions, natural processes, etc., that do not have a mathematical solution with a workable result! The premise is that all processes in nature can have a distinct mathematical expression. If you search, you will find it challenging to shatter this claim! All natural functions behave in an exemplary and surprising manner with complex mathematics that optimizes resource utilization.
