Where do you think the Corona Virus originated?

I have found evidence for a few hypotheses. One is that it started in China. In order to confirm this, we could test if the outbreaks of the virus are correlated with imported food and other goods from China. Also, we might look at who in the United States (and maybe other countries) came in contact with people who had been in China. The more people who had been in China, the more likely it is that they came in contact with the virus and introduced it into the US. We can test if the area of exposure is also correlated with how many cases there were.
