Here's my take on it: I don't think religions are based on lies, but I don't think they're based on truths, either. I think they come about because of what people need at the time that they need them. Like the World Series player who won't take off his lucky socks, or the mother of the sick child who believes that her baby can sleep only if she's sitting by the crib - believers need, by definition, something to believe in.
