I don’t know about a complete list. You also have three sources. First, David Grusch mentions 80 additional witnesses. Then there’s Dr. Steven Greer, who mentions 300 to 500 witnesses in his videos. And then there’s the “To the Stars Academy,” which is said to be purely a CIA affair. I can’t imagine that in the USA you can accuse the CIA of crimes and come from the same place. So, I consider such witnesses to be of higher value. But of course, always with caution. Once CIA, always CIA. So, targeted disinformation is also possible. But the topic has already changed. No more green men, but “there’s something.” Also, how the media in the US report. Once a UFO landing in Las Vegas. Then that in the Mal in Florida. Quite interesting.
One can perceive many things stereotypically. However, I don’t think all UFO witnesses are bought or trying to sell books. Many just want to share their story, and in the past, they were often stigmatized and marginalized. However, that’s becoming less and less common.
