A) How could we possibly know that given so many unanswered questions about life in just our own solar system & the fact we have not (yet) ventured beyond our own solar system in a quest for life?

Google "universe fine tuned for life" or "earth fine tuned for life". Eye opening.

I'm well aware of the fine-tuning arguments. Again, that applies to life as we know it. The truth is we have no idea what might exist and how it might exist beyond a handful of planets in our own solar system. Even then, we are unclear about life in just our own solar system.
