Aliens exist

The world known physics, Stephen Hawking, said that the aliens exist and he tried to make a documentary using his so-called mathematical brain's imagination to illustrate it, well the image was created by using computer of course but he said that the aliens actually exist and they are more advanced than us, human. He also added that there are 100 billion galaxies in the universe and he believes that earth is unlikely to be the only planet that evolves. well, i believe that theory as well though, but no one knows.

and aliens probably also have detected us and might come to destroy earth if they want. well this point, im not too sure. :)

here is one of the images:
