See, my point is that the predictive statement:
"Wherever liquid water is found, (in what they define as a 'Habitable Zone'), that 'life will inevitably emerge";
.. unless supported with either mathematical certainty, (and a set of determinable conditions), or instances of direct empirical evidence, the Chaos view, which
does provide us with a definitive statement, is directly at odds with it.
If neither evidence nor mathematical certainty can be presented, the statement is not scientifically supportable.
Whereas, the Chaos statement about unpredictability being certain ..
IS supportable.
No matter how many exo-environments, with liquid water exist in the 'Habitable Zone', the only supportable statement about emergence of life, is that it is
still totally unpredictable that life will emerge there.
The possibility that life may migrate from elsewhere, and then inhabit that world,
is possible, (using our earthly extremophile evidence and a credible transport mechanism), .. but that it
orginates in that environment, remains, guaranteed, as uncertain.
Cheers & Rgds & thanks for the conversation.
