The version I've found most convincing is that the zoonosis occurred during the virus collection process. Going into cave after cave of cold coronavirus laden air to collect bats with coronavirus, human lungs self select the most infectious variant. Technically not lab leak.

I’m no biologist but doesn’t this fail given there would be no selective pressure for the virus to mutate the covid spike in a cave only occasionally frequented by humans? Or, you need a species link like the once-theorized pangolins.

both are equally likely

I think at this point the zoonotic theory no longer uses wet market start but assumes undetected prior cases as known animal vectors dont get you to the wet market... but the core point on parsimony is right.

Also worth noting the lab leak case is easily disproved - an earlier case somewhere else is its fossil rabbit in the pre cambrian - so after a point absence of disproof becomes evidence.
