Dude,
Sure, you can send me resources via PM. I think it would be a good idea to get some sort of perspective myself before sharing ideas with DS, since he's so young. Maybe if he was older we could "figure it out together" but I don't think that will work so well with an 8 year old. As bright as he is I think he's probably too young to figure out what is BS and what might be valid once you dive into it deeply. We did watch another PBS thing, one on Noah's Ark (basically it stated that this "story" and other stories in the Old Testament actually come from Babylonian mythology). He seems to understand that totally, but then makes bizarre remarks about how reading the Bible will give him good luck.
Thanks again, everyone who commented--I appreciate the fact that we can have discussions like this on this site without it turning ugly.
