You’re correct that the OP as it stands is not a thorough, logical proof in the non-existence of God. A couple of commenters below pointed out the same gap in logic. What I’m leaving out here is my life story from age 9 to age 15. There was lot of growing in those years, and at least one major crisis of faith that I came out of with faith still intact, due to the occurrence of a seemingly unlikely event I desperately prayed for. Ultimately, I believed because I thought it made me part of a club of the blessed, like a Sam’s Club for good luck. I didn’t have any other reasons to believe. It was that plain framing of Pascal’s wager that caused me to step outside my belief and examine it. At the time that I realized my own reason to believe in a personal God looked a lot like the general reasons for believing that Santa Claus is a real person, there was nothing else around to sustain my irrational belief in God, so it collapsed. I was otherwise a very rational person, particularly good at analyzing questions and arriving at useful answers. Pascal’s wager removed my blind spot where belief in God was hiding.
