There are 3 that I know of. The UFO that crashed just off shore in brazil in 1958 almost completely burned up, but 3 thumb sized pieces of metal were recovered. In a mass spectrometer they tested at 100% PURE Mg25. That was IMPOSSIBLE with earth-technology in 1958.
Cattle mutilations : zig-zag cuts but under a high powered microscope no cell is torn, the cut line goes BETWEEN the cells. IMPOSSIBLE even with today's technology.
Finally the strange foil found in the 1947 Roswell debris. You couldn't cut it with scissors, or burn a hole thru it with a cigarette. Wad it up like tinfoil and no creases result, it pops right back to flat again.
Lo and behold, a couple of years ago "memory metal" from the lab is announced : a rubber/metal alloy with PRECISELY those characteristics. In other words, with nanotechnology and quantum mechanics we are just now discovering what has been called "alien" technology.
Bottom line : Arthur Clarke's Third Law : A sufficiently advanced technology will seem like MAGIC to a less advanced technology. That was just as true 2000 years ago when Jesus demonstrated it to today's sceptics who are the blind leading the blind.
OK, you listed 3.
Where is any proof, hard evidence, eyewitness reports.
Show me where the metal samples are and who analyzed them. Its been 49 years, where is the data, who did the analysis, was it peer reviewed?
Cattle, again, proof, impossible? Show me some peer reviewed data. And if it was ET's why come down and mutilate cattle, when they would have the capability of just stealing thousands of cattle?
Strange foil, intresting, really. What proof do we have? Where is the foil? Show me a sample.
I can claim anything.
Show me the memory metal from "the lab" I want the reports, the data the documents. You throw out nanotechnology and quantum mechanics as just words, give me some hard proof.
Bottom line: Arthur Clark is a great science fiction writer, I've read his works. He is a writer, not a scientist, he is not someone to be quoting, any more than an actor.
AFFIDAVIT OF JESSE A. MARCEL JR.
(1) My name is Jesse A. Marcel, M.D.
(2) My address is: XXXXXXXXXX
(3) I am a physician, and I have served in the National Guard since 1978; I am a ertified crash investigator and helicopter pilot.
(4) In July 1947, I was eleven years old and lived in Roswell, New Mexico, where my father, Major Jesse Marcel, was stationed at the Roswell Army Air Field, serving as the base intelligence officer.
(5) One night, I was awakened by my father in the middle of the night. He was very excited about some debris he had picked up in the desert. The material filled up his 1942 Buick. He brought some of the material into the house, and we spread it out on the kitchen floor.
(6) There were three categories of debris: a thick, foil-like metallic gray substance; a brittle, brownish-black plastic-like material, like Bakelite; and there were fragments of what appeared to be I-beams.
(7) On the inner surface of the I-beam, there appeared to be a type of writing. The writing was a purple-violet hue, and it had an embossed appearance. The figures were composed of curved, geometric shapes. It had no resemblance to Russian, Japanese or any other foreign language. It resembled hieroglyphics, but it had no animnal-like characters.
(8) My father said the debris was recovered from a crash site northwest of Roswell. He felt it was very unusual and may have mentioned the words "flying saucer" in connection with the material. He was certain it was not from a weather balloon.
(9) I have not been paid or given anything of value to make this statement, which is the truth to the best of my recollection.
