Secondly, while studying the history of philosophy, I talked about Pascal's interesting probability theory about whether he believes in the existence of God. He believes that God may or may not exist. If God exists and I believe in God, then I will be rewarded. If God doesn't exist and I believe in God, nothing will happen. If God exists and I don't believe in God, then I will be punished. If God doesn't exist and I don't believe in God, nothing will happen. Therefore, people who believe in God will either be rewarded or fined, while atheists will either go to hell or be fined. Anyway, it's better to believe in God. Therefore, if a person is good and avoids evil spirits, he should believe in God, otherwise he is irrational.
