As children of the early space age, aliens populate quite e bit of lore, both harmless and deeply malignant. I went through the “aliens among us” phase and still have family that think that way. On a certain psychological level it’s deeply satisfying, since it “explains” everything evil and wrong as coming from an outside source, thus “we” whoever we are, aren’t to blame. It’s basically an infantile way of dealing with the complexities and difficulties of life. The conspiracist is a supreme example of blame shifting and the myth of innocence. It’s also the highest order of the victim mentality. Fascinating, as Spock would say.
