The White House has struck a blow against UFO conspiracy theorists around the world.

The U.S. government has never been in contact with extraterrestrial beings from other worlds, nor does it possess proof that alien life has ever been discovered, according to a statement from Phil Larson, a member of the White House Office of Science and Technology Policy.

The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race. In addition, there is no credible information to suggest that any evidence is being hidden from the public's eye, Larson wrote in a blog post on Friday, dashing the popular notion that the U.S. government has been secretly storing proof of alien life in New Mexico's Area 51.

The statement was issued in response to two online petitions on the White House's We the People Web site, which allows the public to create online petitions to air the grievances. Petitions that receive at least 5,000 signatures will receive an official response from a member of the Obama administration.

Statement A Response to Petitions

Larson's statement was in response to two petitions: One asked that the government immediately disclose the government's knowledge of and communications with extraterrestrial beings, while the other asked that the government formally acknowledge an extraterrestrial presence engaging the human race.

Although the U.S. government cannot confirm the existence of alien life, Larson wrote that has not stopped scientists from exploring whether life exists outside of our planet. NASA's Kepler spacecraft, which is currently in orbit, aims to locate Earth-like planets that could be potentially habituated by life. In addition, NASA is set to launch an automobile-sized rover called the Mars Science Laboratory, which will study rocks, soils and other geology to search for signs of carbon, which Larson wrote is the chemical building-blocks of life.

While NASA initially funded studies by the Search for ExtraTerrestrial Intelligence (SETI), the organization is now privately funded.

However, Larson has not completely discounted the possibility that human beings will one day make contact with extraterrestrial beings.

Many scientists and mathematicians have looked with a statistical mindset at the question of whether life likely exists beyond Earth and have come to the conclusion that the odds are pretty high that somewhere among the trillions and trillions of stars in the universe there is a planet other than ours that is home to life, he wrote.

Of course, it wouldn't be a good conspiracy theory if the government actually acknowledged the existence of alien life. So X-Files fans, don't give up yet -- the truth may still be out there.
