Focusing on “nuts and bolts” UFOs (many of which these days are indeed high tech or false data) is missing the really important stuff.
The important stuff is their impact on human beings.
Carl Jung wrote a wonderful book on this topic many years ago (long before modern tech muddied the waters):

Jacque Vallee wrote a masterpiece on the pre tech UFOs:

John Mack wrote the best book on the “alien abduction” issue:

This may take you out of your comfort zone—but by getting out of that zone you will discover amazing and wonderful stuff.
Terence McKenna described the UFOs that impact human beings as subverting materialistic science. He gave the analogy of the birth of Christianity during the days of the Roman Empire.
In the old Roman Empire every “respectable” intellectual believed in the Roman Gods. When they heard whispers of the servants of someone who rose from the dead they mocked such stories as primitive superstition. The Roman Empire was the greatest Empire in the history of the world and “truth” about the outside world had been discovered by its brilliant intellectuals.
We know how that story ended.
Human paradigms don’t just get nudged aside—they are overthrown by revolutions in belief systems.
Congress or the US military investigating UFOs would be like the Roman legislature and military in 50 A.D. investigating the truth of Christianity.
The whole idea is laughable on its face.
On this we can agree, perhaps for different reasons.
The important stuff is their impact on human beings.
or just as likely the distractions false reporting creates.
When I was young I read "Chariots of the gods", Roswell, and similar books that touted alien visitations. I also read Amityville Horror. All dis-proven now. As a youth, it was vogue to be 'open minded' about what has since been debunked. As an adult, we should be more discerning of such stuff that is there to basically enrich some author at the expense of gullible readers. Art Bell was 'entertainment' nothing more.
How long has Bigfoot been hiding now?
