I would love to think that extra-terrestrial life does exist but until we actually find anything I will remain sceptical. This is the main reason why I downloaded seti@home to help find proof that alien life does exist.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
