Robert Pattinson, believes Stephen Hawking, is right we should not contact Aliens, as the outcome could lead to the destruction of the human race.
Hawking speaking with his robotic voice reckons that Aliens coming to earth would be much the same as when Christopher Columbus, landed in America, disaster for the native Americans. He is also a fan of the TV series V, about Alien reptiles who take over the earth. David Icke, believes it has already happened and that certain families are repitilian including World Leaders and Monarchs, including George W Bush and the Queen of England.
Pattinson, believes that Aliens, would treat Humans, the same way most Humans, treat Animals, with disdain. Humans are forever culling animals on mass whether it be seals, whales, dolphins, deer, birds, mice , rats, and yet all these animals are actually earthlings to.
Aliens coming to earth would be more likely to come hear to conquer rather than to give a friendly hello.
