I also saw a thing on the history channel that said that without this algae bacteria we wouldnt have existed because it gave oxygen to the planet so if we got that and brung it to Mars we may be able to make Mars like Earth ^_^
It would still be impossible, due to the fact that Mars is much too cold to support any life. Secondly, its atmosphere is not capable of sustaining organisms, either.
