Have aliens ever attacked earth?
Will aliens ever invade Earth?
What would happen if aliens attack and occupy only a small part of the earth, and then do nothing? Will we ever communicate with aliens? If aliens do exist, will the government try to hide it? Why? Are there any aliens? Where can we hide if aliens attack the earth? Is it possible that humans have already made contact with aliens? 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? Don't we alienate aliens by calling them alien? How do you think the world would react to the existence of aliens if proved, as of now? What if the asteroids that killed the dinosaurs was a UFO and we, the humans, are the aliens? How would you lead an alien invasion of earth? What if there aren't any aliens? Where are aliens? What if the asteroid that killed the dinosaurs was a UFO and we are the aliens? How would the world react to the discovery of aliens? Is it true we were really brought to earth by aliens? If I say aliens doesn't require space, Will it be science? Do aliens know about earth and us humans? How many species of aliens had visited our planet? Where are all the aliens? What are aliens? Is it true that aliens built the earth, as well as put humans on it, as an experiment? Did they? Or not? If extra terrestrials attacked the Earth would humans stand a chance of repelling them? If aliens plead for asylum on Earth in return for sharing information, tech, weapons, etc. would the nations of Earth agree? Do you think aliens have been discovered but the government is keeping it from us because it might cause a panic? Why should we talk about aliens existence? If an alien race launches a nuclear missile towards Earth, could NASA defend our planet? If we ever evacuate earth, by what year will we leave earth to colonize interstellar planets? If aliens were to look at Earth, would they be seeing our past? Has NASA found aliens?
