I believe the scientific consensus is that it originated in a wet market in Wuhan.

The "lab leak theory", while not impossible, is also shorthand for a morass of conspiracy theories grounded in racist attitudes towards China. It somehow conflates that the pandemic is China's fault, if not an outright attack from China, while simultaneously downplaying any efforts to mitigate such an attack.

There is an institute of virology in Wuhan, but it is most likely that Covid-19 spread naturally from bats to humans.

• Bat coronaviruses are common in the South China - Thailand - Myanmar region, and viruses jump host species all the time.

• Labs that handle human pathogens are maintained under very high security. The one in Wuhan is BSL4, the highest security rating, and had prior experience handling coronaviruses. Also, the viruses themselves would be marked with radioactive isotopes. Even if they somehow got out of the building, it would be possible to find and quarantine all those exposed to it.

• If it was released on purpose, then we can narrow the list of suspects down to the countries that can reliably make bioweapons and antidotes with close to 100% certainty. That's the US, China and maybe Russia. The US and Russia were among the worst affected, and China wouldn't have released the virus in China.

So the most likely explanation is that it is a bat virus that jumped hosts.

In come the posters who never posted here before to explain that the leak theory is true!

While I have no real input re the whole lab leak conspiracy theory, I do have a fun anacdote from then. I remember pretty quickly after the lab leak option was dropped somebody came with proof for it saying 'we have the telephone data, and the day virus started all the telephones from the lab stayed in one place clearly manipulated!'. This story has a few holes, note first the whole 'we have the telephone data' which is already weird (esp as china refused to cooperate), then also we don't have just one day, perhaps this behavior of phones in a lab is normal. Almost like people are forced to put their personal phones in storage when they suit up (iirc often standard practice in those kinds of rooms). Of course the person bringing up the phones theory didn't think about this. I knew we were in for a wild ride of conspiracies after that one, as it was 'throw stuff at the wall and see what sticks' contrarian theories land. (a thing you often see after a tragedy happens, extremely common in far right circles when the far right does an atrocity, where it is often sort of ingroup signal and signal of cruelty). Anyway, that is just an interesting thing I remembered which I wanted to share, on the subject at hand my opinion is I doubt it was a lab leak, but I also don't think we will ever know for sure, and also we will never find enough evidence that it wasn't a lab leak to convince the people who convinced themselves it was one.

I'm on your page at least - best evidence we had was that it leaked from a Wuhan lab.

Not sure what the conspiracy here is, other than "Rich man has thoughts that come close to an opinion on vaccines. Get the pitchforks!"

Missing the forest for the trees, it feels like - The man has a good point about synthetic viruses.
