Angels and Aliens

You think about the people who claim to have met angels or aliens. You wonder how many of those people have met both angels and aliens.

You wonder how they recognize the difference between the two species. I mean, what if there are aliens that have wings sprouting from their backs, have halos around their heads, and wear white robes? Or what if some angels are skinny hairless little guys with big eyes?

It would be the devil to tell the two apart.

You wonder what Descartes would say.
