For me, I would have to start my response to this here discovery of fishies in the Deep Dark Deep by stating that the Universe gives not the tiniest consideration to how we think it works. Which is why we're always surprised by it.

Over the last few orbits around ol' Sunny Sun Sun out there in the Big Dark Bigness called Space, we've come to realize that our cocky assertions that "Life" requires so many special circumstances that Fermi must be right in his paradox, was (too put it mildly) a bit on the silly side.

First, we keep finding living organisms in places that we're sure there will be none. And so we have to keep going back to those "special" circumstances and make them less special. For my part, I think it would be simplest to say that all "life" needs is enough atoms close enough together that they start dancing with each other. Or, put another way - mass and charge in particular molecular structures give rise to behaviours that us monkeys-in-shoes have decided to call "life". Except viruses - those fuckers are the undead.

Second, if we do find life on other planets and moons (Mars and Europa and those other Sci-Fi darlings are where we're hoping to say "take me to your apex predator, so we can cut it up for answers") it is most likely to be the squishy, slimy sort... Instead of green Zoe Saldanas.

Thirdly, goddamn Tardigrades dude.... Those little bastards will outlive the cockroaches and the death of our Sunny Sun Sun if we give them a chance (we won't, because we're humans and we like to wipe shit out. 'Coz reasons).

Basically, extremophilic organisms are so crazy good at being exactly where we think they shouldn't be, that most of the time, it just makes the smart apes look stupid.

But we're still the only ones on this planet with nukes, so I guess we still make the rules that we keep arguing over.
