Unidentified flying objects or UFOs are still a mystery about who made them or their origins. Well, Head of NASA Bill Nelson, voiced a surprising statement. He said that UFOs could be alien technology. Not only that, he discussed about parallel worlds.
Many people reported seeing UFOs, including United States Air Force pilots. So far, it is not known at all who is behind the UFO.
"I spoke to the pilots and they knew they had seen something, their radar was locked on it. And they didn't know what it was. We didn't know either. We hope it's not our enemy on Earth who has such technology," he said. .
He also did not want to rule out the possibility that the UFO really was an alien vehicle. "That thing is something. So it's a mission we're always on the lookout for. Who's out there? Who are we? How did we get here? How did we become who we are today?" he said.
"How did we evolve? How did we become civilized? And do the same conditions exist out there in a universe that has billions of other suns and billions of galaxies?" continued Nelson.
Even Nelson opened up the possibility of parallel worlds. There is indeed a theory that there are other universes that exist in other dimensions although it is very difficult to prove the truth.
"Today there is even a theory that there may be other universes (parallel worlds). And if that is indeed the case, who am I to say that Earth is the only location for a civilized and organized life form like ours?" asked the NASA boss.
Of course Nelson's statement is only speculation and there has been no evidence so far. "But so far, no aliens," he said, outlining NASA's efforts to search for civilizations out there with the help of telescopes and other technologies.
