Here is a collection of quotes from, NASA scientists, Astronauts, Physicists, Intelligence officers and even the former chief of NASA Communications Systems.................This all speaks for it's self, quite clearly! 
I believe, and I scientifically am certain, that there are endless other living forms out there, including intelligent sentient beings. I do know that there are entire universes of living forms out there.
Dr.Story Musgrave NASA scientist-astronaut "I believe that these extraterrestrial vehicles and their crews are visiting this planet from other planets which obviously are a little more technically advanced than we are here on Earth."
Colonel L. Gordon Cooper (Mercury 9, Gemini-5 Astronaut) "Mission control, We have a UFO pacing our position, request instructions!"
Astronaut Cady Coleman NASAtransmission shuttle mission STS-73"I've been asked about UFO's and I've said publicly I thought they were somebody else, some other civilization."
Commander Eugene Cernan, Commanded the Apollo 17 Mission. (LA TIMES, 1973) "We have contact with alien cultures."
Astronaut Dr. Brian O'leary "In my official status, I cannot comment on ET contact. However, personally, I can assure you, we are not alone!
Charles J. Camarda (Ph.D.) NASA Astronaut "UFO sightings are now so common, the military doesn't have time to worry about them - so they screen them out. The major defense systems have UFO filters built into them, and when a UFO appears, they simply ignore it."
Lee Katchen (former atmospheric physicist with NASA) "In my official status, I cannot comment on ET contact. However, personally, I can assure you, we are not alone!
Charles J. Camarda (Ph.D.) NASA AstronautWe all know that UFOs are real. All we need to ask is where do they come from, and what do they want?"
Apollo 14 Astronaut Capt. Edgar Mitchell "All Apollo and Gemini flights were followed, both at a distance and sometimes also quite closely, by space vehicles of extraterrestrial origin - flying saucers, or UFOs, if you want to call them by that name. Every time it occurred, the astronauts informed Mission Control, who then ordered absolute silence."
Maurice Chatelain, former chief of NASA Communications Systems. "At no time, when the astronauts were in space were they alone: there was a constant surveillance by UFOs."
NASA's Scott Carpenter When asked if he believed that UFO's were real;"Yes as a matter of fact I do." He was also asked if he had ever seen a UFO and he said he had, on his Gemini mission. He went on to say that he tried to take a picture of it, but it did not come out.
Brigadier Gen. James Mc Divitt command pilot of the Gemini space craft. (This interview can be seen on a video tape called Beyond Belief, from United Entertainment, Inc. 1986.)
On May 11, 1962 NASA pilot Joseph Walker said that one of his tasks was to detect UFOs during his X-15 flights. He had filmed five or six UFOs during his record breaking fifty-mile-high flight in April, 1962. It was the second time he had filmed UFOs in flight. To date none of those films has been released to the public for viewing. During a lecture at the Second National Conference on the Peaceful Uses of Space Research in Seattle, Washington, he stated:
"I don't feel like speculating about them. All I know is what appeared on the film which was developed after the flight." NASA Pilot Joseph A. Walker "The evidence points to the fact that Roswell was a real incident and that indeed an alien craft did crash, and that material was recovered from that site. We all know that UFOs are real.All we need to ask is where do they come from, and what do they want?"
Capt. Edgar Mitchell Apollo 14 Astronaut "I was testing a P-51 fighter in Minneapolis when I spotted this object. I was at about 10,000 feet on a nice, bright, sunny afternoon. I thought the object was a kite, then I realized that no kite is gonna fly that high." As I got closer it looked like a weather balloon, gray and about three feet in diameter. But as soon as I got behind the darn thing it didn't look like a balloon anymore. It looked like a saucer, a disk. About the same time, I realized that it was suddenly going away from me -- and there I was, running at about 300 miles per hour. I tracked it for a little way, and then all of a sudden the damn thing just took off. It pulled about a 45 degree climbing turn and accelerated and just flat disappeared."
Mercury Astronaut Capt. Donald Slayton "Let there be no doubt. Alien technology harvested from the infamous saucer crash in Roswell, N.Mex., in July 1947 led directly to the development of the integrated circuit chip, laser and fiber optic technologies, Particle beams, Electromagnetic propulsion systems, Depleted uranium projectiles, Stealth capabilities, and many others! How do I know? I was in charge! (A matter of public record)I think the kids on this planet are wise to the truth, and I think we ought to give it to them. I think they deserve it.
Colonel Philip Corso Army Intelligence officer, former head of the Foreign Technology at the U.S. Army's Research and Development department at the Pentagon. Four years director of intelligence on President Eisenhower's White House National Security Staff
Skeptic Quote -- "Radio has no future. Heavier-than-air flying machines are impossible. X-rays will prove to be a hoax."
William Thomson, Lord Kelvin English scientist, 1899. The body of excellent evidence in respect to ETs is overwhelming and much information has come out. Correspondingly, there would be no easy way to inform the public of the Extraterrestrial existence, and no one government or military group to tell it. The situation is extremely complex, with some of it quite disturbing. The sudden announcement of the true reality of ETs would have a profound effect on Earth's cultural, financial, religious, and social institutions. There appears investigators uncovering undeniable proof of a working relation between members of the Intelligence Agencies; the Pentagon and various off-world races that is totally separate from the perhaps hundreds or even thousands of contactee cases around the Globe. They had better tread softly.
