Hawking: Aliens should stay away from Earth

LONDON (AFP) – Space aliens may exist but mankind should avoid contact with them as the consequences could be devastating, British scientist Stephen Hawking warned Sunday.

"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," said the astrophysicist in a new television series, according to British media reports.

The programs depict an imagined universe featuring alien life forms in huge spaceships on the hunt for resources after draining their own planet dry. "Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," warned Hawking. More>>

How did the Earth get its name?
When was our planet given its formal title, and what are the origins of the word? The name Earth originates from the 8th century Anglo-Saxon word erda, which means ground or soil. In Old English the word became eorthe, then erthe in Middle English. Earth was first used as the name of the sphere of the Earth around 1400. It is the only planet whose name in English is not derived from Greco-Roman mythology. Source
