Lol, I have read much on the UFO thing over my lifetime, many of us that don’t think space aliens are among us have read much about it over the last 60 years, I even had a best running buddy who wrote a book on his space alien friend, if you used to listen to Art Bell you would have heard him on the show many times.

The field has an army of fraudsters and deluded characters.
In addition the Pentagon and the Intelligence Community has littered the subject with disinformation to further muddy the waters.
I have given you some links that are solid.
