We don't have any evidence of extraterrestrial intelligence, but SETI@home can give us such a proof. That's why i'm participating in this project. However, there's no guarantee of success. Thanks to AstroPulse chances of finding a signal increased (which might be an unknown phenomenon, but not a sign from ETi).
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.
