I can agree with you that this trilogy was a great read....or since I had it as audio book...a great listen, in fact one of my favorite
I don't think we shall call it a proof of truth....but the author use much of the beliefs we all have in us and in a nice way.
When you is further out in the series you will more get the impression (or I got) that the circle start again with Adam and Eve...
I also assume that the "dæmons " are our conscience and all in all it is a great read for upbringing and food for young thoughts...as well as old ones
Can be recommended to all who love this kind of stuff, and don't be put off by it is called "children or youth books"
