I don't want to pull the "I'm a statistics professor card", but I'm literally a statistics professor so unless I see an integral over a sample space in the denominator I don't want to hear about likelihood, and especially not when someone's half-baked narrative of possible possibilities gets treated as meaningfully bearing on that likelihood.
Like are we just throwing that word around or is their some objective method that apparently everyone else knows about for now to compute these probabilities and arrive at these conclusions.
