Of course it is not just the book or the recent documentary, it is also the earlier works such as The Hobbit and the lost books found in a cave, along with the recently unearthed middle earth goblets made of a strange substance and mass-produced by Burger King, and of course the many works of art- paintings, etc-- that depict not only elves, dwarves, etc. Taken in totality, how can one help but believe in elves?
Maybe I'm really just ANGRY at elves for how ugly the world is sometimes, and I'm just DENYING their existence out of spite....
