Here’s what we know: People report seeing things in the sky they cannot explain. Reported objects come in all shapes and sizes: saucers and triangles and cigar shapes and everything in between. Glowing orbs and rotating lights have been reported as well. Some people report encountering entities associated with these objects. They, too, come in all shapes and sizes, but most reports of the beings are anthropomorphic. Due to a lack of better explanation, some people conclude (despite all the differences) that there’s a core truth here that the human race is not alone, that it’s being visited or coexisting with an entity that appears to be so advanced and mysterious that it’s nearly godlike. We don’t know if the entities are extraterrestrials, interdimensional beings, or some combination thereof. They are, however, undoubtedly the greatest players of hide-and-seek the human race has ever encountered.
In the early days of UFOlogy, that of the 1940s, 1950s, and some decades later, the extraterrestrial hypothesis was the preferred explanation. But it never panned out; there never was a White House landing or equally clear public revelation. So UFOlogy evolved, only in the wrong direction. An intelligence was still assumed in play, and the search continued to explain what it was. Name your flavor of what it is and there’s now a book, blog, or article trying to convince you of the author’s preferred hypothesis: extraterrestrials, ultradimensionals, interdimensionals, and even demons bent on perverting Christians.
