>we will never know whether the virus started at the lab or the market
It didn't start at the market. They tested every animal there and found nothing, yet they found many infected people there and found the virus all over surfaces there. The market was an early superspreader event, not the origin.

I think there are too many unknowns to state either case as a fact: Did they test every animal that had been there? How? Weren't half of them sold and gone already? Do we know none got loose or came from outside?
