Scientists like Dr. Kevin Knuth (in the article) have been struggling with UFOs because they can’t be taken to the lab for empirical, repeatable analysis. Unfortunately for them, studying UAPs requires adapting scientific methods to phenomena that defy conventional experience.
I would think that such a study would need to combine three approaches: the rigorous standards of laboratory science—despite the absence of repeatability—the investigative breadth of forensic criminology, which identifies causes, patterns, and consequences while also applying empirical methods to all available evidence, and the thorough evidence-gathering of good old-fashioned detective work, which considers all valid evidence, whether material or circumstantial/anecdotal.
Beyond that, scientists would need the mindset of explorers venturing into unknown worlds and biospheres—open to discovering what they can’t yet imagine.
Rabindranath's out-of-body experiences during meditation had him standing before what he thought were frightening gods. Having come to the Lord he now knows exactly what they were.
In our time the gods of old have returned as Space Brothers, Nordics, greys, insectoids, and other monsters.
