I guess Kami's place would be kind hard to get to for most people... [Goku's... not much of a deep thinker. He gets concepts like burying the dead to show respect, but anything deeper than that as far as religion is concerned is over his head.] But couldn't Kami just visit 'em and say "Hey, this is what I'm like" or somethin'? I don't think Dende's gotta deal with that, but if people are confused, he could just clear it up.
