This is stupid. You can't debate facts. Either SARS-CoV-2 escaped from a lab, or it didn't. Unless somebody comes forward to say, "Yeah, I tore my glove while transporting some test tubes and I got sick two days later," we're never going to know for sure.
The only sensible thing to do is assume that it's at least possible that it was a lab leak and reevaluate the risk-benefit tradeoff of this type of research. That is a debate worth having. The rest is just posturing.
