I used to be into that UFO stuff when I was a kid. Read Adamski and Frank Edwards books, believed there really were aliens visiting us. Not anymore. It’s been over 75 years since the Kenneth Arnold sightings and there has never been tangible proof.
Science is excellent at studying stuff that is dumb.
It is really bad at studying something smarter than the scientists.
It is like ants who can’t prove that humans exist.
We must not exist.
