It originated in a city with a research lab that was criticized for bad safety practices. That lab performed gain of function research on coronaviruses, and the strangest element of covid-19 is the spike protein furin site, which enables the infectivity in humans, and is not present in other coronaviruses.

Or we can take the Bayesian approach, and look at the base rate of novel pathogens coming out of China over the past 70 years and determine how many were lab leaks versus not, and realize the majority were lab leaks.

This doesn't mean it for sure was a lab leak, but it does mean it should be investigated, which is all any one reasonable has been saying for the past year anyway.
