> when two extraordinarily improbably events occur together, there is probably a connection
If the alternative hypothesis is that the events are independent, yes. But it is somewhat more common to have labs studying viruses in regions where there are virus reservoirs. So the events "lab studying viruses" and "virus outbreak in local area" are not independent, as both are more likely in regions with viral reservoirs, and in particular, in dense urban areas thereof. A coincidence is not as extraordinary as it may seem.
Thing is, it is not possible to know at this point, as long as the virus does not seem to be bioengineered, whether it was a lab accident while studying animal samples or an outbreak starting in the market.
