Actually that’s incorrect. There’s no consensus with multiple agencies coming to different conclusions ranging from maybe it was to we have no idea.
No one has found any smoking gun. But what is more telling is the conspiratards that dog pile on this topic as if the question of its origin somehow validates all their stupid bullshit over the past 3 years. It doesn’t, and all the anti mask anti vaccine idiots have blood on their hands that people like me will never, ever let them forget.
So until we find actual proof, this remains soundly in the category of unknowns.
