Take a step back:
We've been collecting useful yeasts for brewing and cheese production for a very long time, reusing those who yielded better results.
Same as with plants and animals.
So while I don't believe it is man made or synthetic or anything it is smart to have multiple lines of defense against conspiracy theories.

But we know for certain that SARS-CoV-2 was not created through gain-of-function experiments. It doesn't use any of the standard viral backbones used in such experiments, it has a receptor binding domain that computational chemistry algorithms would not have predicted to work (meaning that nature "invented" it, not scientists), and the virus contains seemingly random differences throughout its genome from all known viruses - that would not be the case for a lab-created virus.
The boring answer is the correct one: this virus evolved in nature, and then spilled over into the human population late last year.
I don't think there is any evidence of this, despite the usual suspects (neocon types on our side, and militarists on the Chinese side) ginning up the case for an "escape from lab" casus belli, but let's get the facts straight.
