Sorry, when you make an assertion, you don't get to demand I justify questioning it. You need to explain why I should believe you.
Your reversal of burden of proof is a red flag that you don't have a good argument.
IMO, it is quite plausible that OoL is extremely unlikely and that our solar system is the only place where life occurs in the visible universe. Not proved, of course, but the possibility is by no means unreasonable.
wasn't demanding, just wanted to hear what your own logic was instead
but it's pointless to go any further I guess as it's getting outside science
the weak anthropic principle can't be falsified so it cannot be argued
I don't think we'll ever hear from "ET" but I do think it's perfectly plausible to find single-celled or simple bacteria elsewhere someday (ie. Europa, comet or asteroid)
If I were saying we were definitely rare or unique, you'd have an argument.
But I'm not doing that -- I'm saying it's a possibility that is consistent with evidence.
The claim that life is common is different. For that, you really need to present an argument that life being uncommon is ruled out.
In your last sentence there you've retreated from "life is common" to "it's plausible life is common". Sure (within the constraints of the Fermi Argument, but that has uncertainties.)
