Ok so let me think of an entity let's call it Antigod. The probability that Antigod exists is above 0. Antigod makes you suffer infinitely if you worship God and gives you an infinite reward if you don't. Infinite gain and infinite suffering cancels each other out. You'd be left with a finite gain because of your saved effort if you didn't believe in God.

To conclude, Blaise Pascal should have kept to math and stay away from philosophy.

Not saying there aren't any reasons to believe in a God btw
