Alas, as John Keel stated, flying saucer intelligences are “in the belief business.” It is conceivable that they are not primarily ET in nature but inter dimensional intelligences that “have been here forever.”
They masquerade as angels and now for those that are fervent believers in the ET hypothesis, as aliens. I suspect that the form they take depends on the historic era in which they are perceived. To paraphrase Whitley Strieber, perhaps they are the face of evolution when applied to the conscious mind.
