We can compare what we do not know to what we do know. Detailed? how detailed? for most of us a simple high school text book of "life" is good enough. All people make up stuff (Philosophy) to self justify themselves. Some us just say "Hey, lets use what we know to self justify ourselves."Well, maybe. It is, of course, predicated on our having a sound working definition of "alive" - which most people think we have, but which we actually haven't.It may be alive. That is a very reasonable stance.
"alive" vs "not alive" seems to be a reflection of humanity's need to pigeonhole everything; Like many such categorisations, it's superficially obvious that it's a reflection of a real dichotomy - but when we look at the details, we find that it really isn't.
Reality is more complex than that. We can easily place most things into one of the two boxes; But there are plenty of edge cases, and when we try to deal with those, we discover that any criteria we use cause problems - they put at least some things into the box we know they don't belong in.
This implies that the entire concept is flawed - that is, it doesn't reflect a factual characteristic of the universe.
The idea that complex systems might be "alive" is entertaining, but cannot be edifying without a detailed and accurate definition of "alive", and no such definition exists (or can be agreed upon). All attempts to define "life" have failed.
Mostly people get around this problem in typical human fashion, by ignoring it and pretending that the edge cases are unimportant and therefore nonexistent. It's possible that they might be the former, but not that they might be the latter.
Alive vs not alive. Its a basic classification. Even a broad one. But its good enough here. I personally do not go universal. But I can make a case for it. We need to understand powers of ten to do that. But it's not testable and speculation so I drop it. I stick to the biosphere. Its big enough that a human might/would think its endless and all powerful. Like my kids thought about me when they were young.
For me, I don't do "its a reflection" or "human nature". "Detailed", for a literal thinker nothing can be detailed enough ... unless they say so. I use "compare it to things we classify as alive and not alive." What does the biosphere more closely align to?
You take the measurement.
