According to a report in The Times, the idea would be discussed by scientists at a meeting of the Royal Society in Britain this week.
Paul Davies, a physicist at Arizona State University, US, will suggest that the search for extra-terrestrial life should be focused right under our noses.
His audience will include representatives from NASA, the European Space Agency and the UN Office for Outer Space Affairs, while Lord Rees, President of the Royal Society and Astronomer Royal, will also lead one of the sessions.
