At this point, this is not a complete black box, “novel virus.” There is a scientific understanding of the virus. There are known related viruses in the wild, just not anywhere near Wuhan. There are multi-pathway paper trails linking this class of viruses to the Wuhan Institute of Virology and the people working there.
I don’t mean to be too harsh on you, the media environment around all this has been so bizarre, how various waves of suppression have ebbed and flowed. But if you’ve known where to look, are an independent thinker, not one who just repeats what the large media bullhorns are trumpeting, and can connect dots for yourself, there’s been discussion, discourse, evidence gathering of the very likely source of this virus since the beginning.
