Aliens know we’re out here

ALIEN astronomers on planets in other star systems almost certainly have the Earth listed as a world teeming with life, said a leading scientist.

Earth observers are probably no more than 20 years away from identifying distant planets on which life exists.

It was likely that other civilisations among the stars, assuming they exist, have already come to the same conclusion about the Earth, said Dr Roger Angel, from the University of Arizona in Texas, speaking at America’s biggest science meeting in Boston.
