Exactly the opposite. I accept that some of the myths may not be true, but I don't mind. Taking everything at face value would be foolish.

The point is that the myths have value and religious significance even if they're not literally true. It doesn't matter that the book of Genesis is a myth: it has religious value anyway. It doesn't matter that the detail of Christ's life may or may not be true: it still has significance and value.

Remember I don't mean myth here as a pejorative.
