The Wager doesn't attempt to prove God, it merely states that you might as well worship, because the cost is small and the potential payoff is huge.

It falls apart because, based on what's actually known, there's no reason to think worshipping might be the thing that condemns you to hell, and not doing so gets you into heaven, rather than the other way around.

Not to mention that "the cost is small" is in the eye of the beholder. I've known people who spend a significant part of their week on religious activities, and that's a huge opportunity cost.

Granted, if your belief is based on Pascal's Wager, and is only to hedge your bets, presumably you wouldn't spend much time on religion. But that also raises the question of whether that style of "belief" would be good enough for whatever god might exist.

Granted^2, spending half of your life devoted to a religion could be deemed a small cost when weighed against the eternity afterward. But then you have to think about the idea that you'll have wasted half of your one and only life if the afterlife turns out not to be real.

At any rate, Pascal seems to have failed to consider that there are thousands of religions to choose from, and that a hypothetical god(s) might punish you for choosing to believe in the wrong one. And might even prefer that you believe in nothing, rather than the wrong one!

That’s the fun thing about the Wager. If the reward is infinite then any finite cost is worth it for any finite probability of obtaining it.

Pascal did actually consider other religions. He just concluded that they were definitely wrong. In his view, either (his brand of) Christianity was correct, or god doesn’t exist.

Yes, my point is that those three arguments may be compelling but they assume that reality is correlated to the shape of their thoughts. What they have in common is that they all miss the insight that you need to actually test your assumptions to improve your certainties, and that's not feasible for theoretical all powerful entities that can bend reality.
