NASA is looking for “signs of life past or present,” NASA Administrator Bill Nelson said, and there are a “small handful” of incidents that “we don't know what they are.”
As it stands today, NASA doesn't have enough high-quality data to make a “definitive, scientific conclusion” about the origin of UFOs, according to the space agency's independent UAP research team's 36-page report that was released Thursday.
“If you ask me, do I believe there's life in a universe that is so vast that it's hard for me to comprehend how big it is? My personal answer is yes,” Nelson said. “It would have to be a very advanced civilization [but] the distances is light years, hundreds of lights, billions of light years away.”
