According to former Space Station commander Chris Hadfield, all the astronauts believe that Aliens Exist. Astronaut Chris Hadfield is a practical man, a former commander of the ISS, and a social media celebrity. He lately went on WNYC's Brian Lehrer show to talk about his life and career when a caller questioned him about the existence of "alien life." Hadfield replied "I don't know of any astronauts who think we're alone in the universe,” Now, he's clearly not talking about the UFO-Area-51 made-up type of aliens. He's commenting on the possibility that someplace out there in space, on some alien planet, there are the bags of chemicals we call beings reproducing themselves like us.
And in that certainty, he's in the mainstream of astrobiological thought, as Lane Wallace described this week. There are so many galaxies, which are packed with so many stars, which are orbited by so many planets ... How could there not be life, even still if we haven't found it yet? In my personal opinion, with the Universe being so large, the probability that we'll ever find Aliens is astonishingly small as well. So do believe in Aliens????
