The CCP (Chinese Communist Party) is highly motivated to advance the narrative that the original spread of this was natural occurrence in a wet market. There is actually not great evidence that this is true but it was certainly the original story promoted by the CCP. The level of responsibility, and loss of face, of an escape from a lab vs. a wet market is tremendous. The lab theory was mentioned in some circles early on and there seemed to be a concerted effort to conflate "escape from a lab" with "made in a a lab" in a way that made it easy to dismiss the lab theories as conspiracy theories.
Probably only a handful of people know, if any actually know, if this outbreak started in the wet market or a lab or somehow else. I haven't actually seen any evidence that horseshoe bats were available at the market despite the early stories of bat soup. Meanwhile, there are two virology labs in Wuhan and at least one or both were studying horseshoe bats and has several strains of coronaviruses. Of course they are all full of denials, but what would one expect when it is known that the punishment from the CCP will be harsh.
There isn't really much public evidence that it escaped from a lab either. So perhaps we will never know. But its not like this hasn't happened multiple times in China in the past.
