In the absence of anything else, the existence of RaTG13 seems like pretty reasonable circumstantial evidence of it being a lab leak. The lab had RaTG13 samples - so either the disease travelled a rather long way from Yunnan to Wuhan or someone in the lab was experimenting with the virus doing something interesting and novel.

My take is that there is sufficient motive for China not wanting it to be a lab leak. It opens up the door for blame and scrutiny, something the Chinese Government hates beyond all other things if we look at their profile of operation.

That alone, and doors that got closed when it came to researching the lab is suspicious.

Whatever it may be, the original sars had a solid origin within 6 months of research.
