"Life likely on Mars" as of how many hundred millions if not a billion
years ago?


Maybe as recently as the last ice-age cycle on Mars.
Life needs what some might call a persistant temp gradient.
Or a phase transition, that constantly transitions from one
state to another. Due to the abundance of water on earth, the
entire surface is one great big pile of nested phase transitions.
Evolution happens at it's best pace on earth as a result.

I could imagine a much slower process on Mars. Lets say
a single year on earth would provide a typical life cycle
on earth. But on Mars, as water melts out from underground
and freezes again as ice-ages wax and wane, a ...single life cycle
might be an....ice-age, not a year.

To me Mars, where life is concerned, is a slow-motion version
of earth. Where the primary water cycle is between the oceans
and the atmosphere on earth...very dynamic. And on Mars the
water cycle is between underground ice and near surface soil.
....very slow.

But that is not AT ALL a reason not to look for life on Mars.
Quite the opposite, it'a a reason to look very hard.
Why?

The question all this is meant to answer is CREATION!
Or how life first began.

Mars just might show us ...exactly...how life first starts.
What the missing link between geology and biology looks like.
