Demonic hypothesis (Ufology)

The demonic hypothesis is a position in ufology that proposes UFOs are deceptions perpetrated by demoniacal (Satanic or otherwise) forces, intended to beguile unwary humans and open channels to engage in spiritual corruption or physical possession. In some variations of the hypothesis, these forces are thought to be creators of homunculi (by way of explanation for Greys), while others posit a more clearly spiritual nature, suggesting the UFOs are purely illusory.
