Nonsense. Without a study having material from Mars, this is pure speculation. Microbes, bacteria, fungi, algae, etc, need preexisting life to grow on. These clowns know better, or do they? No.
"Microbes, bacteria, fungi, algae, etc, need preexisting life to grow on.
These clowns know better, or do they? No." Most do, some don't:
"Lithotrophs: Inorganic compounds are the main source of energy for lithotrophs.
These bacteria get their nutrients (inorganic compounds) from the minerals in rocks.
Bacteria are formed of carbon, oxygen, nitrogen, hydrogen and phosphorus.
They also consist of traces of other elements.
So they need to obtain these nutrients from the environment for survival.
Lithotrophs get most of these nutrients from rocks."
And there's this:
"Oct 20, 2006 ยท by Chad Boutin. Oct. 20, 2006 3:35 p.m.
A Princeton-led research group has discovered an isolated community of bacteria nearly two miles underground that derives all of its energy from the decay of radioactive rocks rather than from sunlight.
According to members of the team, the finding suggests life might exist in similarly extreme conditions even on other worlds."
Of course, none of this proves life does exist on Mars, only suggests that it might have, might still.
