Sia was the most recent guest in James Corden’s famous Carpool Karaoke sessions. Besides fabulous singing that took place, Sia also admitted to believing in aliens after seeing a video where a former Canadian defence minister stated that “the American government are working with five different alien race”. She didn’t need any more convincing.
Along with her are many more celebrities who also believe in extraterrestrial life. In 2014 Halle Berry was on the David Letterman show where she said, "My ego doesn't tell me that we're the only ones who survived ... it might take us 20 years to get to those other life forms but I think they are out there.”
Will Smith’s son Jaden is also convinced that we are not alone. When he met President Obama he asked him if there was extraterrestrial life to which the President responded that he could neither confirm or deny their existence.
Famous fighter Muhammad Ali has claimed to have seen 16 different UFO’s over his lifetime. He said that “if you look up in the sky in the early morning, you see them playing tag between the stars.”
During a GQ shoot Katy Perry admitted, “I believe in aliens. I look up into the stars and I imagine: ‘How self-important are we to think that we are the only life-form?” Then in a Rolling Stones interview she said “I see everything from a spiritual lens. I believe in a lot of astrology. I believe in aliens."
Robbie Williams has witnessed 3 different UFO encounters. While talking with Joss Stone he said, “Seriously, I want to go out and investigate these things. I’m stopping being a pop star and being a full-time ufologist [….] I’ve been visited by aliens.”
Tom Cruise, who is a member of the Church of Scientology, undoubtedly believes in other life forms. The doctrine of the church believes that alien life forms actually live inside of us humans. Cruise went so far as to build an $11 million alien bunker for when the aliens arrive. "Are you really so arrogant as to believe we are alone in this universe? Millions of stars, and we're supposed to be the only living creatures? No, there are many things out there, we just don't know."
And then there is Stephen Hawking who is actively supporting the search for intelligent alien life with the Breakthrough Listen Initiative even though that could mean the human race may be wiped out. “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational [….] If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.”
