Still out there: The White House has officially denied any knowledge of alien life, but continues to search
The White House has said there is no sign of aliens – but it is still looking.
Staff were responding to a petition that accused the government of covering up contact with life beyond Earth.
Phil Larson, from the White House Office of Science & Technology Policy, officially denied knowledge of alien life and denied they had withheld information from the public.
He promised scientists are still on the search for extraterrestrial life.
'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,' he wrote in a blog post entitled 'Searching for ET, But No Evidence Yet'.
