Mine came from realizing all of the religions have the same basic stories all credited to their deity as the cause, yet all saying the other deities didn't exist or were false gods.
Ah yes, that's the other good point. Really they are parts of the more general incoherency: "My religion is correct, while all the other religions, current or from the past, are mere superstition."
Then there's my favorite, Pascal's Wager: "Why not accept my particular God? What do you have to lose?" Advocates of the Wager never seem to consider what Zeus's opinion might be.
No that's not his assumption. Pascal's wager is supposed to be an argument to believe in "God", but it is too general. It doesn't determine in which god. So the argument doesn't work.
