Logic would indicate that ET life must exist somewhere in the universe(s). One day we will find it, what we do in our small way with the seti@home programme is a small building block to achieving this eventually.
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.
