We have long passed at least my owner personal "threshold of evidence" to assume that Mars had life.

That bar is pretty low. I am not hard to convince.

We don't have a baseline by which to contextualize the situation statistically. There is no p-value we can meaningfully satisfy. Worse than that, evidence required for a belief derives from the risk of being wrong.

Is there a discussion of what evidence WOULD be enough for the scientific community to say loudly "There was life on mars". Because right now it seems all risk and no utility, so the evidence bar would be really high.
