Well, you’ve obviously been reading the skeptic’s reports on these incidents.
I can tell you that back when this phenomenon began to attract a lot of attention, I read dozens of reports by qualified observers and investigators, as well as experienced ranchers, who all stated the same things over and over and over again. Namely, that these kills were unlike anything they’d ever seen.
No animal or human tracks. No blood. No signs of struggle. The exact same organs taken time and time again, while the rest of the carcass remained untouched. Always happened in the wee hours of the night, and done without rousing guard dogs and other animals. And yes, the surgical precision of a surgeon used to remove the organs in every case (most kills being discovered within hours - not days).
I’ve heard and read interviews with people who’ve been ranching their entire lives, and every one of them stated that they well knew the difference between what they saw, and a kill by a predator.
Again, I’m not supporting the alien theory. I’m only saying that there’s never been a clear explanation for this phenomenon.
Actually, a few ranchers have seen the UFO’s involved in taking their animals.
