They might have to process the fungi, lichen, or microorganisms before they are eaten, but I do not think any of that will be beyond science to sort out.
OK, you let me know just how you plan to fix the carbon in methane into the "soil".


How about nitrogen, phosphorus, or any of the couple hundred other nutrients that are present in actual soil? And of course all the fungi and bacteria that go to breaking down dead material into nutrients usable by plants.


My guess is that you would need to start wtih some real Earth topsoil, with a bunch of chemical fertilizer, and grow a bunch of stuff, purely to compost it, and maybe in a few thousand years you'd have a start on a small patch of topsoil. Remember that earth top soil has been developing for - what? a billion years? When did the first single celled life exist on land?

I wont go into all of this here, but I believe all the basic building blocks to life are already there. Water, carbon, oxygen, and it is well-known that fungi and bacteria can produce these minerals and chemicals from the their environment. I have seen an 's'-shaped something in an image which could be a worm, who knows?


current flowing water perhaps (red arrows)


and maybe even a bug hole in 1M132267223EFF05AMP2937M2M1 (unlikely to be gas from sub-surface due to the almost perfect roundness of the hole.)


I suspect the dust/soil on top of this rock may be spores from some kind of fungi.
