I think you're on the right path. Take a look at thisThis article is misleading. Most viruses held in labs are not genetically engineered and originate from natural sources. Just because this virus isn’t genetically modified does not mean the pandemic did not originate from a lab accident. I doubt we’ll ever know the truth, but the fact is, an accidental release from a lab is still plausible especially given the poor laboratory practices in China, notably selling carcasses of lab animals for consumption (!!!).
People simply do not want to believe this is possible, hence articles like this. Not exactly scientifically rigorous.
