I have been following UFO related discussions for decades.
It is a messy rabbit hole—filled with con artists, .gov disinformation agents, liars, lazy researchers, kooks, etc.
For anyone new to the genre I would recommend the works of Jacques Vallee as the place to start. He exposes the fraudsters and disinfo folks and how they work:

Then, once you are fully inoculated against the liars and crazies, you can begin to look at the topic seriously.
The world is stranger than we can imagine.
There are some solid sources out there (Vallee being a great one), but what a rabbit hole.
Thx for that link.
I can’t afford this book right now, but what is the author’s (and /or your) opinion of Whitley Streiber?
