Aliens almost certainly exist but humans should avoid making contact, Professor Stephen Hawking has warned.
In a series for the Discovery Channel the renowned astrophysicist said it was “perfectly rational” to assume intelligent life exists elsewhere.
But he warned that aliens might simply raid Earth for resources, then move on.
“If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans,” he said.
Prof Hawking thinks that, rather than actively trying to communicate with extra-terrestrials, humans should do everything possible to avoid contact.
He explained: “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.”
Radio beams have been fired into space in the hope of reaching alien civilization. In the past, probes have been sent into space with engravings of human beings on board and diagrams showing the location of our planet.
Prof Hawking said: “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
“The real challenge is to work out what aliens might actually be like.”
The program envisages numerous alien species including two-legged herbivores and yellow, lizard-like predators.
But Prof Hawking conceded most life elsewhere in the universe is likely to consist of simple microbes.
In the recent BBC series Wonders of the Solar System, Professor Brian Cox, a physicist from the University of Manchester, also suggested life may exist elsewhere within our solar system.
He said organisms could be present under the ice sheet that envelops Europa, one of Jupiter’s moons.
Professor Cox added: “Closer to home, the evidence that life could exist on Mars is growing.
“We will only know for sure when the next generation of spacecraft, fine-tuned to search for life, are launched to the moons of Jupiter and the arid plains of Mars in the coming decades.”

Just read it with an open,unbiased mind.
TIME: Why does chaos reign now?
Li: Of course there is not just one reason. The biggest cause of society’s change today is that people no longer believe in orthodox religion. They go to church, but they no longer believe in God. They feel free to do anything. The second reason is that since the beginning of this century, aliens have begun to invade the human mind and its ideology and culture.
TIME: Where do they come from?
Li: The aliens come from other planets. The names that I use for these planets are different . Some are from dimensions that human beings have not yet discovered. The key is how they have corrupted mankind. Everyone knows that from the beginning until now, there has never been a development of culture like today. Although it has been several thousand years, it has never been like now.
The aliens have introduced modern machinery like computers and airplanes. They started by teaching mankind about modern science, so people believe more and more science, and spiritually, they are controlled. Everyone thinks that scientists invent on their own when in fact their inspiration is manipulated by the aliens. In terms of culture and spirit, they already control man. Mankind cannot live without science.
The ultimate purpose is to replace humans. If cloning human beings succeeds, the aliens can officially replace humans. Why does a corpse lie dead, even though it is the same as a living body? The difference is the soul, which is the life of the body. If people reproduce a human person, the gods in heaven will not give its body a human soul. The aliens will take that opportunity to replace the human soul and by doing so they will enter earth and become earthlings.
When such people grow up, they will help replace humans with aliens. They will produce more and more clones. There will no longer be humans reproduced by humans. They will act like humans, but they will introduce legislation to stop human reproduction.
TIME: What are the aliens after?
Li: The aliens use many methods to keep people from freeing themselves from manipulation. They make earthlings have wars and conflicts, and develop weapons using science, which makes mankind more dependent on advanced science and technology. In this way, the aliens will be able to introduce their stuff and make the preparations for replacing human beings. The military industry leads other industries such as computers and electronics.
TIME: But what is the alien purpose?
Li: The human body is the most perfect in the universe. It is the most perfect form. The aliens want the human body.
TIME: What do aliens look like?
Li: Some look similar to human beings. U.S. technology has already detected some aliens. The difference between aliens can be quite enormous.
