Extraterrestrial propaganda talks in depth about God and true spiritual principles. Do they see us as children believing in a Santa Claus and think they are simply encouraging a fairytale?

This is a quite useful analogy, for this is indeed the case. They understand the spiritual teachings that have been embraced through the ages in various cultures, but they regard this as simplistic wishful thinking, and can repeat the ideas and the words but do not believe them personally, and do, in fact, see humans as simpletons engaged in a kind of magical thinking and see this as a weakness they can manipulate and do quite extensively to their own advantage.
