This all goes back to the creation story. Was Iluvatar a small g god or the capital G God? Were he and his gang possibly alien visitors from space who seeded Middle Earth with life forms or genetically manipulated existing ones? Did in fact Middle Earth start as Tolkien said or was it a myth told by the beings of the time? We have the same religion verses science controversy today. But as we all know, we are not allowed to talk about religion or politics here.
