It's a false dichotomy between natural and manmade. What about a virus that naturally occurred in a bat cave, was studied in a lab, and escaped from the lab later? What if that virus mutated unintentionally while in the lab? And what if its mutation was encouraged by researchers in the lab? Occam's Razor, to me, suggests that it's more likely the virus came from the nearby infectious disease lab than from the wet mar…
Why couldn't it have been transported into the city on trucks and vehicles coming from sampling sites? Or hitchhiked in bat guano on a worker's boot who visited the wet market? You've generated 2 possible outcomes and gone "yes these are the only possibilities". But why? There was a whole train of transportation bringing things into the city for the lab. Of course, if it was from that timeline, then the whole "lab es…
On your latter point, I'll just say that the virus likely needed some time to mutate into a human infectious form, and most of what we're talking about is, where and how did that happen?
