Do you have any clue as to what the high-power electron
microscope that the rover would need to carry to see such
would weight? And a biology kit is utterly useless in case
of millions of years old fossils.

You've lost me. My point was that we should be sending
science packages that can either prove or disprove that
life either once did exist on Mars, or perhaps still does
in certain locations.

You think this is a simple task?
Care to design a few experiments? What specifically
would you send to either prove or disprove that life
exists or once existed on Mars? If we re-sent the
Viking experiments and got the same mixed results
at a new site - where would that get us? What
would you send instead?
If you don't find it in one location does that mean it
doesn't exist elsewhere?
