SCIENCE genius Stephen Hawking reckons aliens exist - but it would be a fatal mistake to contact them.

The physics professor takes a guess at what aliens might look like in a new documentary, which shows yellow lizard-like predators and large green herbivores.

What does he know ALf said that these Yellow Lizards are just being friendly.

The real enemy has always been the Dalek Race.

ALf has visited all the galaxies and found that the Dalek Race is feared totally on every inhabited planet. Even the Large green herbivores will have nothing to do with The Dalek's.

But the boffin fears ETs may come to raid Earth's resources. He said: "I imagine they exist in massive ships, having used up all the resources from their home planet.

"If aliens ever visit us, the outcome could be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans."

Hawking, 68, who is paralysed by motor neurone disease, said alien life was likely as the universe has 100billion galaxies, each containing hundreds of millions of stars.

He added: "The numbers alone make it perfectly rational."

Stephen Hawking's Universe airs on Discovery Channel, May 9.
