Still seems fairly speculative to me. I think it's very likely that there was life given all the water but this is still a ways away from a smoking gun.

- zokier 1y agoSmoking gun needs sample return, and the current outlook for that mission is not great.
- rrmm 1y agoYou are right: this is indeed no smoking gun (and it isn't hyped to be one). This is more like "we can't rule out life having created this, but there are alternate explanations which have also not been ruled out". Unfortunately most of the evidence is going to be like this. The chances for better evidence would probably require a sample return of some sort, and even then I wouldn't expect a smoking gun (either way).
- andrewflnr 1y agoWell, not exactly. By my read, the known alternate explanations are very strained, only there for propriety. They don't have a really clear idea how this could have formed abiotically.
