I think Minmus had life at some point in its past

[Nerbal The Second]

If you have the Breaking ground DLC you have probably seen Minmus's Olivine formations, there is a piece of dialog when you Analize it, hinting at a possible ocean in the past.

There is also green sandstone which forms from Organic waste collecting on sandstone when you do an analysis of the Greensand stone it says that Minmus's flats are salt flats and some other things that aren't important for this discussion. this makes me thing that Minmus once had an atmosphere and an ocean, but it evaporated only leaving salt behind and the dry seabed which makes up Minmus flats.

[Superfluous J]

Organic and Life are far apart. It's like saying Minmus had metal on it so there must be an automobile factory somewhere.

Minmus is really small so unless it lost a lot of mass it's unlikely it could have kept an atmosphere dense enough.
