The universe is far to vast for these humans on earth to be alone. Other life exists, I firmly believe.
I've always had an intense interest for anything relative to the study of space, space travel, and other worlds. I feel that the Seti@Home project helps to ingrain a feeling of community and participation to any who share in the process.
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.
