In your linked Nature study:

Although the evidence shows that SARS-CoV-2 is not a purposefully manipulated virus, it is currently impossible to prove or disprove the other theories of its origin described here

In your linked WHO report:

Assessment of likelihood In view of the above, a laboratory origin of the pandemic was considered to be extremely unlikely.

In your FBI article which blames China lab with no evidence:

Many scientists point out there is no evidence that it leaked from a lab. And other US government agencies have drawn differing conclusions to the FBI's.

Why did you even link a news article citing Energy Dept. making the accusation with, by their own words, "low confidence"?

I’m happy to be proven wrong but my understanding from people discussing the experts is that the lab leak theory is most likely

Your own evidence argues against your point. Your understanding is wrong. Scientists will ofc hedge and say the probability it was an accidental release from the Wuhan lab is 'not zero', but this is what being precise with language and honest looks like. It does not mean they believe it is actually what happened or that it is even likely. There is no actual evidence to suggest it was an accidental release, and even less that it was engineered.

Biologists know that as the population of the planet increases so too will the occurrence of pandemics. Just look at the last century or so: Spanish flu, Hong Kong Flu, Bird Flu, Aids, Bubonic Plague. Look earlier than the 1700s and you get 1 pandemic a century at most.

;tldr get used to it and stop believing conspiracy theories on something that is going to be a regular occurrence.
