[Mark17]

It could be as simple as demon manifestations.

I suggest that demon manifestation may not be simple at all, but incredibly complex. Complex enough to destroy the human paradigm.

In fact, complex enough for these "demons" to turn our reality upside down and claim the God of the Bible is fiction and they are our "real" creators.

Some "contactees" have reported that these creatures have said "we are here...and your God is not." Who ya gonna believe?

Yep

I seem to recall that a few who claimed “encounters” said they felt they were in the presence of ...... evil.

Hmmm.......

From a Biblical perspective that is the only explanation. Unless one believes they are natural phenomena, which is not plausible. The idea that they are secret government tech is also not believable.
