UFO theories are more than just alternative descriptions of how the world is. They often come with ethical guidelines, explaining how we ought to relate to aliens. For example, ZetaTalk makes much of the distinction between "Service-to-Others," the philosophy of the Zeta race that has come to help us survive the passage of Planet X, and "Service-to-Self," the philosophy of other aliens who have won over the world's leaders. The Luciferian Liberation Front, on the other hand, draws on Ayn Rand's Objectivsm to come to the opposite conclusion -- don't trust aliens who advocate altruism. And Alien Resistance claims that aliens are agents of Satan (and that aliens are actually angels or other divinities -- a reversal of the von Däniken/Sitchin thesis that angels and other divinities are actually aliens).
