¿FBI acepta existencia de ovnis?

Durante años aceptamos que la vida se compone de un grupo establecido de elementos quimicos,que los seres vivos necesitan unicamente oxigeno para vivir.Sin embargo hace poco se encontraro una bacteria que respira arsénico. La bacteria en cuestión, llamada GFAJ-1, como comenta la NASA en su página, es un miembro de la familia Halomonadaceae, que habita normalmente los océanos.

Este hecho sorprendente nos ofrece una nueva perspectiva y nos hace pensar que la vida pueda existir en cualquier parte del universo.¿porque los seres vivos deberian necesitar exclusivamente los elementos presentes en la tierra?¿por qué solo deberián de respirar oxigeno?

El FBI dió a conocer también hace poco que el OVNI en Roswell,Nuevo México fué cierto,y lo que es falso es que la astrofísica malaya Mazlan Othman no es la embajadora para el Espacio,ni tendrá que organizar la respuesta mundial en términos de diálogo ante un eventual contacto con una raza alienígena.

The FBI and UFOs
Flying Flapjacks, Saucers, and Saw Blades
04/06/10
If you’ve ever watched The X-Files or other sci-fi shows like it, you may think that investigating unexplained phenomena is one of the FBI’s investigative responsibilities—right along with terrorism, espionage, white-collar crime, etc. 
In fact, the FBI was only occasionally involved in investigating the possibility of UFOs and extraterrestrials over the years. The first Bureau investigations we are aware of began in the summer of 1947—the time of the now well-known incident in Roswell, New Mexico. A rash of reports of flying objects—some shaped like “flapjacks,” saucers, discs, and even a large circular saw blade that supposedly hit a lightning rod on top of a church—started to surface and make headlines across the nation. 
Concerned citizens reported many of these strange sightings to the FBI. That wasn't surprising, given that the Bureau had investigated airline crashes such as the Hindenburg disaster in 1937 and aerial dangers like the balloon bombs launched by Japan toward the U.S. Pacific Northwest near the end of World War II. The FBI’s lead role in protecting the homeland during the war was also well known, and the Bureau remained front and center in ensuring national security as the Cold War began to unfold.
Initially, it was not clear how UFO sightings should be handled. FBI Director J. Edgar Hoover recognized that the Air Force—then part of the U.S. Army—clearly had the lead in such issues, but he did want his agents to investigate any “discs” recovered for their potential impact on FBI responsibilities. 
The Army did want the FBI’s help—at least at first. On July 30, 1947, the Bureau issued this notice to all of its offices:

(B) Flying Discs – The Bureau, at the request of the Army Air Forces Intelligence, has agreed to cooperate in the investigation of flying discs….You should investigate each instance which is brought to your attention of a sighting of a flying disc in order to ascertain whether or not it is a bona fide sighting, an imaginary one or a prank.

Three years later, that policy changed. A July 1950 FBI statement said that “the jurisdiction and responsibility for investigating flying saucers have been assumed by the United States Air Force. Information received in this matter is immediately turned over to the Air Force, and the FBI does not attempt to investigate these reports or evaluate the information furnished.”
From this point, the FBI’s cases on UFOs dropped off dramatically. Neither the public nor the Air Force sought our expertise as they had during the first few years of the Cold War.
There were a few exceptions. In 1977, for example, the Air Force informed us of the end of their “Project Blue Book” investigation of UFO reports. And in 1988, we were asked to look into the release of what appeared to be a 1952 classified document concerning a UFO-related top secret government group called “Majestic 12”—we determined that the document was a fake.

Los detalles de la  cara para hacer frente a supuestas reuniones entre militares de EE.UU. / personal de la Marina con la vida extraterrestre no se conoce con gran precisión debido a las versiones contradictorias de los representantes de lo que ocurrió en esas reuniones. Sin embargo, habida cuenta de tres fuentes independientes revelan esas reuniones, dos de los cuales se han confirmado personalmente por el autor como creíble, se puede concluir que los contactios extraterrestres entre  militares están actualmente en curso. Los oficiales retirados de los dos servicios militares que integran el Departamento de la Armada (Marina de EE.UU. y el Cuerpo de Marines de EE.UU.) ocupan un lugar destacado en la administración de Obama. Estos incluyen Dennis Blair, director de Inteligencia Nacional (ret Admiral, USN), James Jones, National Security Advisor (retirado General, USMC), y Charles Bolden, administrador de la NASA (retirado General, USMC). En consecuencia, un programa de enlace militar de EE.UU. y extraterrestre que se a filtrado  a la opinión pública por agentes de la Marina de EE.UU. de un contacto secreto entre los servicios del grupo de trabajo que la administración de Obama para avanzar con un anuncio público sobre la realidad de la vida extraterrestre.(http://www.scientificsevidences.org/ufo/index.php?option=com_content&view=article&id=132:militares-de-eeuu-estan-en-contacto-con-extraterrestres-segun-fuentes-independientes-&catid=53:exopolitica&Itemid=18)
