Paranormal, as I see it, involves belief in what one might qualify as "magic"
"Illuminati" involves one particular secret society from the 18th century and the belief that the oligarchs running the west are in some way related to that organization
"Illuminati" is obviously related to "conspiracy" and "secret societies"
history is full of proven and generally accepted conspiracies
it's only since the CIA came up with the term "conspiracy theory" to mock those who reject the official story of the JFK assassination that the term "conspiracy" is considered fringe and related to fruitcake theories
Ghosts are beyond science, they can be tested, but not using physical instruments which mainstream science provide, or at least how they using it. Because you can easily detect ghosts with EMF meters.
They won't understand it, because the reality is designed so smart, so we can go in circles all the time.
Emotions are basically frequencies, if scientists think the logical thinking is the only way (left brain), they won't be able to understand it, because only people who can unlock the right-part (which they think it's meaningless), basically their mind needs to operate on the right frequency, so they can understand it.
Not all things can have logical explanations.
Quantum isn't logical.
teleporting isn't logical as well, although they manage to do it: sciencealert.com/…
I had before Aliens proposal, but it was too narrow, so Paranormal is the broader one based on the previous experience, but still it struggling with some activity.
Beyond Earthlings is a bit ambiguous in my opinion.
@VishnuJK If you mean beings, then yes, Paranormal includes that as well.
