  Well, perhaps you know that none of the recent findings are evidence of life, but in my conversations with others I have perceived a great deal of confusion on this point, even among scientifically literate colleagues. Also, the fact that we have zero understanding of the probability of abiogenesis is, in my experience, a greatly under-appreciated fact. I speculate that the way findings are reported contributes to this confusion. Also, at risk of incurring a flame, I'll gently point out that you are folding into this confusion and reinforcing it with your language: "likely precursors everywhere, habitable bodies" ... we absolutely do not know that these conditions are "likely" precursors, which is a statement about a probability we know nothing about and as for "habitable" we do not actually know anything about whether or not a body is habitable in the sense of likely to spontaneously form life.
