Since aliens exist and UFOs are seen hundreds of times daily around the world, and the closest Earth like planet is Proxima b at 4 light years away, then time travel must be real. You see, aliens wont spend 4 years traveling at light speed to get here. Instead they will spend several minutes to travel here. So if they travel faster than light speed, they are also traveling through time. So UFOs not only travel through space, but also time. They can be used as time machines to travel to selected moments in history of any planet anywhere in the universe. Watch the video, and see what you think.
