Strange beings come out of “the heavens” (from the stars). They appear in the form of glowing disks, crosses, or objects in the sky. They grant struggling human beings different forms of cultural and technological knowledge (laws, writing, agriculture, ritual). They warn them about the end of the world, teach them about the nature of the soul, generally scare the shit out of them, and even sometimes engage them sexually to create divine-human hybrids. That’s the history of religions. That is also the modern UFO phenomenon.
