What if the asteroid that killed the dinosaurs was a UFO and we are the aliens?
Are we really aliens on earth? Are we aliens on earth? Are there UFOs? Would this nation or the world panic if we knew aliens existed? Has NASA found aliens? If aliens were to invade Earth tomorrow, what would happen? Are we human beings aliens to planet earth? And if not, then are we acting so? If aliens landed on earth what would they look like most likely? What if there aren't any aliens? Have astronauts ever seen aliens or UFOs in outer space? What will happen if someone build a spacecraft like UFO? Have aliens been to the earth? Have aliens ever attacked earth? Have astronauts ever seen aliens? Are NASA astronauts aware of aliens in UFOs? If aliens were to look at Earth, would they be seeing our past? What if aliens exist and their level of technology is so advanced that they can see all the creatures on the earth, but being millions of light years away from the earth they can only see dinosaurs and are afraid to contact us? Will aliens ever invade Earth? Are there such things as UFOs? How likely is it that there are aliens? What would happen if aliens attack and occupy only a small part of the earth, and then do nothing? Does alien and 'UFO' really exist? Is there any scientific proof? Who has seen aliens or UFOs? If we detected a planet-killing asteroid, is there anything we could do about it at the present time? Have anybody seen UFO or something like that which proves alien may exist? Did an alien spacecraft crash at Roswell? Is there any evidence that aliens visited our planet? Is it true we were really brought to earth by aliens? What is a UFO? If I say aliens doesn't require space, Will it be science?
