jangobongo writes "Does intelligent life exist anywhere besides Earth? Are regular churchgoers less likely to believe life has evolved on other planets? Do more Democrats or Republicans believe in extraterrestrials? And if alien life makes contact, what should we do? These questions were asked on a poll released last week that shows that two-thirds of Americans do believe that life exists on other planets, and of that group, 90% say if we receive a message from another planet we should reply. The poll was commissioned by the SETI Institute and the National Geographic Channel."
