Evidence for early life in Earth’s oldest hydrothermal vent precipitates
>http://www.nature.com/nature/journal/v543/n7643/full/nature21377.html
Although it is not known when or where life on Earth began, some of the earliest habitable environments may have been submarine-hydrothermal vents. Here we describe putative fossilized microorganisms that are at least 3,770 million and possibly 4,280 million years old in ferruginous sedimentary rocks, interpreted as seafloor-hydrothermal vent-related precipitates, from the Nuvvuagittuq belt in Quebec, Canada. These structures occur as micrometre-scale haematite tubes and filaments with morphologies and mineral assemblages similar to those of filamentous microorganisms from modern hydrothermal vent precipitates and analogous microfossils in younger rocks. The Nuvvuagittuq rocks contain isotopically light carbon in carbonate and carbonaceous material, which occurs as graphitic inclusions in diagenetic carbonate rosettes, apatite blades intergrown among carbonate rosettes and magnetite–haematite granules, and is associated with carbonate in direct contact with the putative microfossils. Collectively, these observations are consistent with an oxidized biomass and provide evidence for biological activity in submarine-hydrothermal environments more than 3,770 million years ago.
When men go to Mars we will likely find signs of life, that is if Mars resembled early Earth. The galaxy is probably packed to the brim with life.

And much of it never gets anywhere. The ways it can go wrong are boundless.

who's to say we've got anywhere

I'm counting multicellular life as major accomplishment here.

That's p. deep brah

this. unicellular life will be fucking everywhere, multicellular life not so much.
This better not be the case because say goodbye to space colonization. The environmentalist's wail to protect the microbes on the moon/mars/your ass will be so thunderous the earth will crack open.
