re: #1 Fairly Sure I’m Still Obdicut
Well perhaps your question would be better answered by the author, but I took “our” to mean we as in life (not just us humans) did not begin when where or how we think it did.
1. Far earlier.
2. In very different circumstances, perhaps far and away more vastly.
3. Not tied to a tiny habitable zone.
4.-This might point the way to panspermia/transpermia theory-the idea life or life’s building blocks are all over the universe, far more commonly than we had previously thought. Maybe life or it’s essential precursors did come from space rather than sparking here.
