U.S. confirms that aliens have not been in contact with Earthlings

The White House has no hard evidence that extraterrestrial life exists, or that alien beings have visited earth, but still looking.

The Obama administration has responded to a popular demand sent to Washington with over 17,000 signatures from citizens concerned about the assumptions neighbors in the universe.

The Government replies because it is committed to respond to any claim that meets enough signatories in less than 30 days within the program 'We The People'.

And in this case, there were two claims : one calling for "immediate release" of "government communications with extraterrestrial" and another to recognize "formally the extraterrestrial presence and its relations with human beings."

A space policy expert answers, diligent, "The U.S. government has no evidence that life exists beyond our planet or an entity that has contacted alien or has been related to any member of the human race, in addition, no information credible to suggest that the public have withheld evidence. "

To the relief of universal mystery lovers, there is still hope because scientists are still searching.

"This does not mean that life outside our planet is not being discussed or explored. In fact, there are several projects to understand whether there is life beyond Earth," writes Phil Larson, Office of Science Policy and Technology White House.

Now they work at least three programs seeking life outside the planet.

The SETI program, funded by NASA and is now in private hands, pointing telescopes to the sky for any sign or sound of another world.

Within NASA, the Kepler spacecraft in orbit tries to detect other planets in the Milky Way. And the Mars Science Laboratory, about to launch, studying rocks and other debris that could indicate a living past.

Larson argues that it is possible that extraterrestrial life exists, but almost impossible for Earthlings to find.

"Chances are that somewhere among the billions and billions of stars in the universe exists another planet besides our own where there is life," he writes.

"However, the chances of any being contacted, especially intelligent, they are extremely small because of the distances involved."
