You don’t know shit
You are correct. I know nothing other than what I read. Virology is not my field. The real science with all the technical terms is also difficult to grasp. Political posturing and deceptive spinning is easier and way more fun.
I do believe we can dismiss the theory that the Wuhan Lab intentionally bioengineered SARS-covid-2 as part of a biowarfare program. I suppose it is possible, but it is not plausible in my not so humble opinion.
It is also remotely possible that the Wuhan Lan accidentally created SARS-covid-2 while engaging in forbidden 'gain of function" research. However, while they may have done a sort of 'gain of function" research according to a definition used by Rand Paul, they apparently did not do the type that would create viruses that can infect humans. So I think this is also implausible.
That leaves the theory that the Wuhan Lab isolated a naturally SARS-covid-2 from an infected bat or other mammal, some staff got infected, and the virus subsequently "escaped" the lab. While this is considered unlikely based on current evidence, similar things have happened, so it is plausible.
Sill, I do not know shit. None of us really know shit. All we can is read from the best sources we can find and try to sort it out. I have my take, others have theirs. I'll change mine when the information and / or my understanding calls for it. It is not a matter of who is right; it is about what is true.
