Life on Mars?

Okay, what do ASAers have to say about this latest revelation of science?

I've got a question. Maybe some of you geologist types know the answer.
(Where is Glenn Morton now that we need him?)

Notwithstanding the theological implications of life on other planets,
or even whether this space chunk actually contains remnants of early
primitive life, how do we know this meteorite came from Mars? Why not
planet Earth, for example?

The Moon is believed to have been launched from our planet early in its
history by a massive asteroid (comet?) that smacked earth and propelled
one-sixth of it into lunar orbit giving us something to smooch by. Why
couldn't other chunks have been blown into orbit and then fall back to
earth even billions of years later? This particular chunk, whether
replete with life or not, could as easily be Earth debris as Mars stuff,
could it not?
