Abraham and the three angels, by Tissot
There are about 1 billion catholics in the world, of which all have been taught, that angels don't have physical bodies. Even those who don't believe in their catholic faith, still think the same way as they've been taught since childhood. The old "augustinian lie" thus has deceived these peoples, who also, after the protestants, are the political and cultural leaders in the world. So these ufo believers are, without them knowing it, believing a catholic lie. Had Christianity stood for and preached what the Bible says about the physical and spiritual nature of angels, belief in "aliens" would never have developed.
