That calculus isn't as uncommon as you'd imagine; most people who take a religion very seriously end up having experiences they identify as "the presence of God", and anyone who leaves a religion they'd taken seriously must confront that bit of evidence. I'm another such case, although I have to cede the most impressive of these stories to the acquaintance of Eliezer (sorry, can't find the link to this anecdote) who had frequent, detailed, coherent visions and eventually decided that the most likely explanation was hallucination rather than contact with a deity or superintelligence.
