Alien Life Is out There
One of [the] world's leading scientists makes the claim in a new television documentary series. Stephen Hawking says [that] in a universe with 100 billion galaxies, each containing hundreds of millions of stars, it is unlikely that earth is the only place [where] life has evolved.
"To my mathematical brain, [the] numbers alone make thinking about aliens perfectly rational," he said. "The real challenge is working [out] what aliens might actually be [like] ."
Hawking says that they could be microbes – basic animals [such] as worms, which [have] been on Earth for millions of years, but suggests that extraterrestrial life could develop [much] further.
"We only have to look [at] ourselves to see how intelligent life might develop into something we wouldn't want [to] meet," Hawking said. "I imagine they might now be living in massive ships, [having] used up all the resources from their home planet. Such advanced aliens [would] perhaps become nomads, looking to conquer and colonize whatever planets they can reach."
The scientist, [who] is paralyzed by motor neuron disease, warned that contact with alien life could spell disaster [for] the human race.
"If aliens ever visit us, I think the outcome would be much like when Christopher Columbus first landed in America, which didn't turn out very well for the American Indians."
