Neil Degrasse Tyson releasing a book about ALIENS? What changed?! Grift or legit?!

Neil Degrasse Tyson as famously been known at scoffing at those that question whether or not extraterrestrial life has visited earth. He has also made fun of or looked down at those who believed there were craft and has said things against pilots or other people who have seen it. But now, has he seen the light? He has written a book talking about Potential of alien life and what to do should it arrive. Is this a Griff or has he absolutely seen the light? Kristian Harloff gives his thoughts. #UAP #UFO #Alien #Aliens.
