It’s been said that the devil is in the details. But then the principle of parsimony, not to mention a lack of evidence, seems to preclude any rational belief in multiple universes . . . or devils. I find it more reasonable to believe in the 14 billion year old universe that we seem to perceive and find ourselves in, the inexplicably low entropy at the beginning, and, of course, first cause—infinite universes and devils are just too peculiar, unsubstantiated, and extravagant.
