Who's More Gullible?

I've read and heard many people state that those who believe the claims made in "The Da Vinci Code" are extremely gullible. Most of these people are firm believers in Christianity. Let's look at this from a non-biased perspective, shall we? Who's more gullible? One who believes that a male got married to a woman, had children with her, and his lineage is still alive and well today or one who believes that a man resided in his mother who never had intercourse, that this man was perfect every day of his life, that he sacrificed himself for the world's wrong doings, and that he rose from the dead three days after his death? Looking at it from a non-biased perspective, how can one possibly say that the former is more gullible than the latter?
