The virus wasn’t tampered with. Th lab in Wuhan is “GAIN OF FUNCTION” testing.
read it again. Gain of function means nudging viral samples so they gain functions on their own without human gene editing or modification that can easily be traced.
Why now? Why not 5 years ago? The animal markets have always been there.
Occams Razor.
This argument is bootless. Viral mutations and spread happen according to anomalous diffusion statistics that are inherently chaotic at outset.
For those who do not know what chaotic means, it is extremely sensitive to initial conditions. Most of which are actually unknowns. Risk is always there, but details are never initially predictable.
That is why you have infrequent intermittent epidemics like Spanish Flu, or more recently SARS, and not constant evolution of new crossover viruses.
It seems that crossovers happen more on the timescale of decades than mere years. (Though I’m excluding crossovers of unviable infections that don’t go anywhere, of course).
None of the above argues against the lab escape theory. As the OP details it’s possible. Just your specific line of reasoning here oversimplifies, hence the downvotes.
