Stephen Hawking believes we should fear aliens, which would probably come to Earth in search of resources and bent on our destruction.
The venerated cosmologist says in a new Discovery Channel series that he thinks aliens exist, but we should do everything we can to avoid meeting them. Any life intelligent enough to find us would probably be seeking resources, he says. And that would likely be bad news for humans.
"We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet," he says.
