The virus did not come from Wuhan. The first known cluster of cases was in Wuhan. This is where China first identified and then quickly notified the international community that there was a new communicable disease.

Many of the original identified victims had no relation whatsoever with Wuhan, and virologists have traced the virus to several individuals throughout Hubei province as early as November. Virologists tracing the virus history through DNA shows a significant history to the virus before Wuhan.

SARS-CoV-2 shows no signs of having been bioengineered and plenty of markers of cross-species adaptation. Furthermore the closest coronavirus strain known to mankind is significantly (50 years of forced evolution) far from SARS-CoV-2.

Biological laboratories are located in many cities across the world. Given all of the scientific evidence we know about the likely species-jump origins of the virus and its history before Wuhan, it's it a bit of a tired theory (as in definitively unreasonable in the number of required assumptions) at this point that the virus escaped Wuhan's high-containment laboratory?
