In response to an actual petition, the White House was forced to disclose the following information today:
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.
However, that doesn't mean the subject of life outside our planet isn't being discussed or explored. In fact, there are a number of projects working toward the goal of understanding if life can or does exist off Earth.
Just in case you were wondering….
