Should we teach kids that all of those hundreds or thousands of gods might be real? No? Why not? Couldn't we be wrong about them not existing? So, if, in fact, one of those gods is real, you have an imperceptibly better chance of telling your children the truth than I do. But if, in fact, all of them are human creations, then you're just confusing them with a bunch of old superstitions....all of which have some pretty crazy ideas about how the world works and how humans ought to treat one another. Sure, some are better than others, and some are more modern than others, but if they aren't true, why confuse kids with odd fictions in the guise of "One Truth"?
