This seems to be stronger than the Antarctica one found a few years ago. News at 11. If confirmed, it is a game changer. Like life everywhere basically. If life found on Mars, Europa, etc., first thing to do: Is it DNA like Earthy life or something else?

Although I would not completely rule out the possibility of microbial life being common virtually wherever and whenever there was once liquid water in our solar system, I think that this is unlikely and, therefore, I still would guess that this claim of evidence for alien life is probably just seriously flawed -but I guess we shall see....

He didn't wash his hands.
