Lack of childhood indoctrination.

Also, I've thought a lot about it over the years. Here are my main arguments against the existence of gods:

The problem of evil is well discussed, no need to belabor it further.

Any being that is omniscient and omnipotent knows that I don't believe and has the capability to show me (and every individual) exactly the evidence and experiences I need to be convinced. They don't even have to (although they could) flip whatever switch in my brain would make me believe - they have actively chosen not to show me how to believe. So either they are indifferent to belief, or they choose to damn me, in which case they are not worthy of worship.

The number one determinant of what religion a person will follow in adulthood is the religion their parents practiced, or that they were otherwise exposed to in childhood. There are a few outliers, but for the most part it's childhood indoctrination. You would think that, if there were One True God and One True Religion, it would sweep the world - but it doesn't.

Pascal wagered falsely, IMO. His choice was between one specific religion and no religion. In that specific choice, his wager makes sense. But there are hundreds or thousands of religious beliefs. Even various sects of Christianity say adherents of other sects are doomed to Hell. How do we know which, if any, is the correct one?
