> Im not sure theres a single place on earth with water but not without life.

I'm not sure I'm not having a hard time parsing this triple negation :-) Are you saying that all places on earth with water also have life?

Yes, it's saying (water ∧ ¬life) = false, which implies (¬water ∨ life) = true, which implies water ⇒ life.

I'm not quite sure that I had this original thought myself or read it somewhere but an alternate definition of life is the ability of membranes to hold water. One of the first things to happen upon decomposing is the organism can't hold water anymore. I find it an interesting criteria that for example classifies virii as non living.
