Life From Mars?

Life From Mars?
Life From Mars? Is it life? Or is it a bit of dried clay that somehow assumed a shape that resembles the form of certain bacteria on Earth? The segmented object at center is one piece of evidence marshalled by a team of NASA and university scientists to suggest that a rock from Mars holds evidence of ancient life. Spacecraft have taught us that the Red Planet once possessed the conditions needed for life. Might life have arisen there, and could it exist today? These questions could be answered by future spacecraft, and the tiny, elongated forms found within a Martian meteorites have renewed popular interest in exploring other worlds.
