Panspermia, an idea more commonly known as the theory of cosmic ancestry, says that life could have originated through stellar means. That is, no abiogenesis took place on the Earth itself, bacterium was simply transported here through a comet, or something like that. It's largely dismissed by the mainstream scientific community, because its evidence is scant and I'm inclined to agree. Moreover, it doesn't solve the problem of explaining how life originated. All it says is "life comes from space because life comes from life." Many consider this to be some form of creationism (not necessarily Biblical, as there are other forms of creationism than Christian fundamentalist, but creationism nonetheless).
The Mars connection begins with a meteorite that landed in Antartica, which appeared to contain fossilized organisms. Proponents of panspermia cite this example as hard evidence that "nanobacterium" can be transported here from meteorites.
