What I'm saying is that we don't have strong (any?) evidence that SARS-CoV-2 is the result of gain of function research. It is entirely possible but the majority of the scientists who do gain of function research say it's unlikely (given what we know today, which might change).
Again, a credible source saying the opposite is appreciated.

There is analysis that suggests that SARS-CoV-2 wasn't engineered. However, if you were intentionally giving it to a bunch of animals in batches with some interspecies mixing, you wouldn't really expect it to look any different than a natural jump.
