Seems like there are a lot of OTHER things that would preclude life on mars [sic].

As LJ noted, ALH84001 has a Gya date, where conditions may have been remarkably different than those of today. Further, one has to specify what one really means when referring to "life on Mars": life at the surface or life in the sub-surface. Indeed, ALH84001 is not a "documented" sample in the true sense (i.e., location and depth of ejection unknown).
