When you're sitting in the middle of the Wyoming prairie and you hear hoof beats, expect to see horses - not zebras (or unicorns).
I assure you, that whatever mutilations you've seen have had nothing to do with UFO type mutilations
OR were exceedingly long after the fact.
And, you SOUND like you have NOT researched the topic much at all, if at all.
For example. You still have not BEGUN to explain these PERSISTENT BASIC FACTS.
1) Cow/Cattle are in say the more or less the middle of a field--or wherever in the field but say away from fences etc.
2) Farmer and family watching from farmhouse 50-a few hundred feet away.
3) A silent intense light appears above the cattle in the field.
4) It has snowed since the cow has been in that spot.
5) No tracks to or from that spot across the snow.
6) Cow is seen to rise in the air in the light and disappear into a darkened space.
7) within 20 minutes to an hour, the cow is returned and obviously dropped from a significant height to very close to the same spot the cow was taken from.
8) Vet is called immediately and arrives (in some cases from a neighboring farm) very quickly.
9) Vet notes no tracks to or from the spot.
10) Vet notes incisions and total lack of blood. Has absolutely no conventional explanation for the incisions or lack of blood. Asserts no human method known to him could achieve the particular types of excisions or the total lack of blood. Not a drop of blood on the snow. Not a drop of blood left in the animal.
11) Farm dogs and other critters walk a WIDE BIRTH--50-150 feet around the carcas even when the path leads right next to the carcus.
12) No flies appear on the carcas for at least many months. Anything close to conventional decay does not set in for many months.
Freepy, you have NOT BEGUN to explain any of the above persistent key points of virtually all authentic UFO type mutilations.
You have not BEGUN to explain such facts to yourself, much less to us.
