if there are creatures born somewhere else in the universe, and they have evolved to live for hundreds or thousands of years, and they have managed to develop long-lived craft, and can even live and breed on them, then what, exactly, is paranormal or supernatural about that? it's entirely consistent with a darwinian concept of the natural universe.
and, again, that's the point, or at least it is to me; it helps me make sense of religion, in a way which i've never been able to otherwise get my head around.
it would be useful if we had a little more positive evidence. but, we may find out one day that all the evidence was right in front of us.
