I'm half expecting "There was life on Mars, and it was from Earth" (microbes somehow transported on a meteorite).

It would be particularly epochal to find some life in our solar system that had a completely separate origin, but life is such a prolific thing once it appears, some small-scale panspermia with Earth as the source wouldn't be entirely surprising.
