Now thats just insane and your theory is very plausible!!

I disagree.

Any life they ever find on Mars will be tested. If the life is found to be totally different than life on Earth (and different than those microbes intentionally put on that space probe), then it probably formed independently on Mars. If it is found to be the same or very similar to those organisms intentionally put in that space probe, then we know the life did not form independently on Mars, and it came from the contamination.

It would not be difficult to tell if the life is related to those organisms.

This brings up another point -- if life is someday found on Mars and it is found to be similar to, but not exactly like life on Earth, then that could mean:

(1) Life on Earth could have originated on Mars Billions of years ago and brought to Earth by a chunk of meteor blown off of Mars (Mars Seeds Earth with life).

(2) Life on Mars could have originated on Earth sometime in the past and carried to Mars by a chunk of meteor blown off of the Earth (Earth seeds Mars with life).

(3) Life on Earth and life on Mars were started elsewhere, but chunks of meteors/comets carrying that life seeded both planets billions of years ago (i.e., life on both planets have a separate common origin).

Covering up evidence of life? Like hell!

This is the first stage of terraforming Mars. Data gathered by Mars surface missions is sufficient to determine which Earthian extremophiles will be able to thrive on Mars. These primitive but hardy lifeforms have demonstrated their facility in adaptability, life on Mars will be a piece of cake. But, being Earthlife, their very presence will be the beginnings of altering the atmosphere (and climate) of the red planet. Rapid mutation will enable these micro-organisms to utilize the high levels of solar radiation and organic chemicals in the soil to first produce various "heavy" gases which can be held by the meager surface gravity. The higher atmospheric pressures will then allow water to exist in a liquid state on the surface. At this stage algae will be introduced to the small lakes which will form and, through photosynthesis, will begin converting the huge amounts of available CO2 into oxygen.

It begins at a very slow rate. But the rate of change increases exponentially. Within 75 years it will be possible for humans to walk on the surface of Mars with no more than a supplemental oxygen mask.

Native Mars life?
We'll find out who's fittest.

Obviously a preemptive biological attack against the impending martian armies.

Yes we do know how to screw up an ecosystem with introduced species, and it seemed to work in the movies.
