When I first heard, early on, that there was a BSL-4 lab in Wuhan studying the virus, I knew it came from there. China's evasiveness and deception just proved it to me.
Now, I was open to the wet market theory, but unless/until they found the animal, it was never the explanation. And so far, over 5 years later, they still haven't found it and you can be sure China's been looking for it every single day since it first happened.
