IF, and that's an infinitesimally small if, all other religions were proven false, and it was only atheism or christianity, then sure, Pascal's wager makes sense. In reality it does not make sense because Christianity doesn't have anything to make it more compelling than any other ancient supernatural beliefs.

Even if Christianity were true, we still don't know everything about the supernatural. The Bible talks about "other gods". Lucifer killed a tiny fraction of the people Yahweh killed. Why should we trust Yahweh? His plan gives 2 year olds leukemia. He told Moses to murder his own son. He thinks women are property. He confused the languages of the world because we were getting too capable. He's not good.
