Would the Middle Earth saga be considered a religion in of itself?

Would the Middle Earth saga be considered a religion in of itself? Im not talking as related to Christianity or Judism or Islam or any other "real" religion, Its just that Tolkien did the books so comepletly that there is an actual God (Iluvitar,or Ea) and and afterlife, and it is mentioned that there will be an ending of Middle Earth (possibly the apocolypse?) dont get me wrong, im not some cult leader trying to convert people, i just want people's thoughts on the subject.
