George, it sounds like you need to read
Inside Narnia: A Guide to Exploring The Lion, the Witch and the Wardrobe by Devin Brown, he seems nearly as equally as heretical as you.

Yes, I wonder about all this stuff....but usually I don't voice them...today's just different.
But anyway, Devin Brown, goes into the whole possibility of other (unaccounted) visits to Narnia, pointing out the picture from a friend of the Scrubb's house must have been given to them by someone who has been on a Narnian ship whose journey has been, as I said, unaccounted for. There's another of evidences Brown raises to support this...but I think those questions remain unanswered because the mystery is part of the strength of the Narnia series - especially in publication order! :)
