> Apart from being mathematically completely unlikely we're alone in the Universe That's a false assumption, since we don't know the probability of our existence. If the probability is low enough, then it's not "completely unlikely". Particularly if you limit it to our galaxy, since there's little reason to suppose aliens in another galaxy would know of us, let alone make a trip millions of light years. > if you go and read dozens of reports and accounts about alien encounters, most of them match with one another. You can say the same thing for similar religious experiences and various other paranormal phenomena. But what's more likely, that human psychology combined with Earth-based phenomena is the answer, or that aliens travelled light years to mess with us?
