I am viewing all this removed from the human condition, And I’ll explain why.
IMO, an earthlike planet in a solar system 3000 light-years from here would have the same opportunity for abiogenesis as earth. The mathematics don’t change .
H2O on earth is exactly the same as H2O in another galaxy. Objectively speaking, the same natural constants we have identified on earth are exactly the same throughout the Universe. The same table of elements is valid at the other end of the universe.
The probabilistic dynamics apply there as they do here. Humans have nothing to do with any of this.
Life on Earth is proof that life can and has evolved via Abiogenesis, on Earth as well as in … !
Consider that we have landed equipment on planets in our own solar system many times and how many pieces of equipment have left out solar system on lonely journeys into deep space, only to crash into an earthlike planet orbiting a sun like ours.
A few bacteria may have been shielded and lain dormant. We may have seeded a planet in space.
The earth has been bombarded for billions of years with debris from deep-space collisions., Comets, asteroids from all corners of the universe have landed on earth. Bacteria may have been deep inside some of these space rocks. They do here on earth and don’t require oxygen or sunlight at all and can remain dormant for thousands, if not millions of years. It’s is chemistry, not requiring any energy other than chemical exchanges.
Perhaps an impact like a planetary collision and it enormous energetic consequences is causal to some very special chemical reactions and self duplicating polymer formations.
I understand your perspective of the human relationship to the earth, our exclusive environment and I completely agree wit your desire to keep that perspective in all considerations.
I just imagine that a similar solar system with similar planets as earth clear across the universe, would also have produced life at some evolutionary stage.
Robert Hazen is confident that life exists elsewhere, by reason that it is “necessary” if there is a hospitable (dynamic) environment and “sufficient” raw chemicals to follow the laws of chemistry and “chiralty”.
The sheer enormity of chemical reactions on suitable planets almost guarantees that life has evolved elsewhere. Hazen estimates a near certainty of life having evolved or will evolve elsewere in the universe. He believes it is “inevitable”, given what we know about how life evolved on earth. We just don’t know exactly when and where on earth.
I guess what I am trying to say is that free will (choice) is an emergent ability in living organisms and may exist elsewhere.
But the natural dynamical mechanics of the universe are always deterministic, even if there are local variables.
