"All the differences among people
of Earth would seem small."
Bill Clinton on Jimmy Kimmell show, April 2, 2014
'We know from our fancy telescopes that just in the last two years more than 20 planets have been identified outside our solar system that seem to be far enough away from their suns - and dense enough - that they might be able to support some form of life.'
He added: 'So it makes it increasing less likely that we're alone.'
But when Kimmel pushed on whether there actually are aliens, Clinton responded: 'I'm trying to tell you I don't know.'
'But if we were visited some day, I wouldn't be surprised,' he added. 'I just hope that it's not like Independence Day, the movie - that it's, you know, a conflict.'
Clinton assured Kimmel that soon after he became president, he instructed his aides to research Area 51, the Nevada military facility, to make sure there were no aliens there.
He also had the Roswell papers - which detailed a reputed UFO sighting in 1947 - reviewed.
He said that while he had no evidence of aliens, their existence could have surprising benefits for the world.
'It may be the only way to unite this increasingly divided world of ours… think about all the differences among people of Earth would seem small if we feel threatened by a space invader,' Clinton said.
'That's the whole theory of Independence Day. Everybody gets together and makes nice.' Source.
