first of all, you're agreeing with me, I said I'd want to see proof, and you're saying what the proof would need to consist of.
However, you are not addressing that there has been zero natural origin evidence, but they've all along been saying it's the likeliest, despite the Wuhan lab, and they've not been considering gain of function even though the US has been funding it in China at that lab.
The fact that the virus just popped out of nowhere more or less without the normal pedigree is strong evidence against a natural origin theory. It's pretty clear at this point that it was a lab escape, in my opinion.
