Dear John,
So far, no evidence of life has been found on the moon or in any of the robotic explorations of the planets.
However, there MAY be evidence for past life found in metorites from Mars that have fallen to Earth. This is a very controversial area of research. I suggest you check out the Wikipedia article at http://en.wikipedia.org/w...le_evidence_of_life.
But we will keep looking!
