Who is the best rock band ever?

Well, I believe there isn't a best rock band in the world because if there were then everyone would like that band. Because not everyone likes Zeppelin or Sabbath, but I just want to know what you think. I think Sabbath would be the best because they are the originators of metal. Zeppelin, some of their songs are kind of gay, because they have some weird Reinance horn or some thing, but some of their songs rock. Sabbath though, phew, man I love 'em, because their songs are so heavy and dark. What do you think?
