Pascal’s wager is not intended to be a philosophical proof for God, or even an argument by reason. It is intended to be thought provoking; to bring a person who doesn’t understand God to a better understanding.
If the wager is not helpful for you, don’t worry. There’s another path for you.
Pascal’s wager brings possibilty about the existence of a personal god who has Heaven and Hell; a possibility out of many other possible beliefs that one could say. He thinks that it’s enough to take this characterized God into considerarion just because it’s one of the possibilities and if we don’t and that kind of god exists, we are doomed, this looks like a very irrationel dishonest bet which can be said about any other possible characterized belief, “if it happens to be true we are destroyed for not accepting it” .
It is similar to proposing that Aliens who will do experiments on those who disbelieve in them exist, and that it is better to believe in them just in case, a game to be played where we must wager:
1- To believe in them, be on their side, so we could gain some supernatural powers if they happen to exist.
or
2- To disbelieve in them and be in their experiment project in case they were real.
This approach is used by those who have a specific faith to others who don’t, you have nothing to lose if you believe in my faith! Therefore believe in Personal God/Baf Aliens or lose, it’s your “choice”.
This analogy however does not offer any better understanding for aliens, just like Pascal’s wager, it doesn’t offer any better understanding for God.
