We are talking about a one-off event that happened in a totalitarian country with a huge penchant for purging undesirable information.
Even experts are on a shaky ground when almost all primary information sources are controlled by a non-cooperative party. The only thing concerning the origin of the epidemics that is beyond reasonable doubt is the genetic sequence of the virus. We do not even know for sure who the first covid-19 patient really was and when.
Of course it is hard to speak with confidence in such a situation.
