the lab leak theory has nothing to do with science

The origins of COVID is not concerned science in your view for what reason? It's a scientific theory. The only proof to the contrary is from biased individuals who in some cases were directly involved in the granting of money for the purposes of extremely controversial gain-of-function research to the Wuhan Institute of Virology.

So, what's not science about the origin of a virus? Your comment makes zero sense.

You don't get SARS-CoV-2 by combining an RaTG13 backbone with a pangolin spike in a lab -- it is still decades of evolution away form SARS-CoV-2 which you don't get via passing it through a dozen generations of mice. There's no evidence WIV was ever doing GOF research (although they did collaborate with GOF research that happened on US Soil), it is entirely circular logic. The idea that WIV employees were treated for SARS-CoV-2 is entirely evidence free, nobody knows the names of those employees, China has claimed those were 3 samples submitted in Jan from community collection which is rejected out of hand because it comes from China. The whole lab leak theory is that its a coincidence that the pandemic started in the city that had the lab, and the theory that coincidences never happen.

This is what actual science looks like:
