Plus COVID-19 positie blood samples in France from Nov/Dec 2019. That alone is reason for me to believe that the Wuhan lab has nothing to do with it. It just so happened that Wuhan was the first major outbreak.
That being said, I don't know how the origin would help us right now. We have working vaccines. So the solution is to push vaccinations as fast as possible. The origin of the virus isn't that important right now.
