I think that the ET life does exist but using our present technologies we can't find it.
The Seti@home program in addition to its' scientific role has a very good feature - it unites the mankind. It makes us realize how small the Earth is.
It makes me feel the citizen of the Earth.
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.
