Things happen. I know a lot of people like to poke fun and poke holes at people like this. But, there's simply a lot of things that have happened throughout our existence that really does make you wonder what's really out there. Mathematically you'd have to believe we cannot be the only possible existence of intelligent life.

 

And honestly, our species isn't all that "intelligent" in the grand scheme of things. That's probably why other lifeforms avoid this dump of a planet to begin with. Joe Rogan said it best years ago. But we probably look like cancer or a disease or some type of mold on a sandwich from outer space to everything else that exists. 

 

This isn't even the weirdest case I have heard though. There was another researcher that was found dead in his Polish hotel room during one of his tours with his research and findings. He was becoming paranoid according to his mother and said if he turned up dead that it wasn't suicide. When they found his body it was shrouded in mystery of course but they said they found very thick, black & tar like substances that he had spewed up prior to his death. His veins were also discolored, etc. 

 

But, as it was already pointed out on here. If someone did dig too deep they more than likely caught the eye or attention of their respective Government and were silenced for good because of their research. That's common in most countries and it covers a wide variety of reasons, etc.
