I live about 50 miles north of Elmondorf AFB, and I'm terribly at aircraft identification. So I see UFO's all the time. However, I know them to be always terrestrial.
The most likely explanation is vandalism since they are infrequent and random.
All of the soft tissue of the animals, the eyes, the mouth, rectum cored out, genitals are removed with surgical precision. Evidence shows in many cases where large internal organs removed without corresponding large openings in the flesh. ALL of the blood is drained, not one drop of blood on the carcasses or the ground, or anywhere near the scen, no footprints or any evidence of human activity. Over 10,000 cattle mutilations from all over the world have been reported going back to the 70s, and there have been reports going back to the 17th century.
Linda Moulton Howe reported:
"One of the principal hallmarks of these mutilations is the complete absence of blood in the animal’s carcass or at the mutilation site. Strangely, these animals have almost always been completely drained of blood.
Another peculiarity is that tracks or footprints are never found around the animal’s body, even when weather conditions like rain, frost or snow would have favored their presence; no footprints, tire tacks, signs of a struggle - nothing at all. These mutilations also bear a remarkable similarity to one another. Perhaps one of their most notable characteristics is commonly referred to as a “jaw swipe.”
This term refers to a condition whereby one or both sides of the animal’s jaw are stripped of all tissue right down to the bare bone. For some unknown reason this often occurs on the left side of the animals face but not always. The right side is occasionally stripped in this way. Less frequently both sides of the jaw are removed. Also immediately evident are the removal of one or both eyes and ears.
Examination of the animal’s hind quarters often show evidence of “anal coring,” a procedure whereby the anus is cored out to a depth of several inches and used as a portal for extraction of the animals rectum. Other circular or teardrop shaped orifices cut into the torso also appear to be used for removal of organ systems located within the body cavity. Such a feat is impossible to carry out through such small openings, but most of the mutilated animal’s viscera are usually missing.
Forensic examination of the incisions used for extraction reveal that they appear to be made by a laser-like instrument. The incisions are clean, precise and carefully executed. A Denver pathologist named John Henry Altshuler, M.D. [5] examined Lady’s (a horse) carcass a few days after her body was found.
Actually, the Navy calls them "Unidentified Aerial Phenomena" or UAP, and at no time did they ever suggest the UAP was extraterrestrial.
Of course the Navy is not going to say they are "extraterrestrial". Tic Toc shaped objects, hurling though the air, no visible means of thrust, no wings...
"Navy pilots reported to their superiors that the objects had no visible engine or infrared exhaust plumes, but that they could reach 30,000 feet at hypersonic speeds."
Then there is the testimonies on Dr. Greer's "Disclosure" DVD, where some 400 professionals, military personnel, scientist, and the like, credible persons testifying to incredible things that happened while during their careers.
UFOs witnessed traversing one side of the horizon to the next in seconds, making right angle turns at hypersonic speeds. Right, these are made in the good ol' USA. Got it.
You don't seem to comprehend the vastness of space, [...].
You're assuming that an advanced technology from another planet a million years ahead of us is using technology of 2020 planet earth. These advanced crafts are not moving from point A to point B in a linear fashion using thrust type propellant. Who knows what is possible? What is clear from your comment is that it reeks of "man's poverty of imagination."
If you saw evidence that house was raided by a neighbor, you wouldn't go to great length to debunk the fact that your neighbor invaded your home.
These ETs are out there, they are real. Why is it so "fantastic" that they wouldn't be visiting us? Why would it be any more incredible than the case above of a neighbor invading your house if the evidence points to it?
Why is this fantastic? I'll tell you, it's because of "poverty of man's imagination". That is the only reason.
To me, it's no more or less matter of fact than the neighbor example. ETs are our neighbors, and like all neighbors, they drop in once in a while.
That's not crazy, it's logical as logical can be logical.
