Not new ones. It was insane how often during the pandemic I explained that it could have been natural or man-made and at that time, it would be impossible to know.
Our focus at that time needed to center on stopping the spread BUT some folks rage against uncertainty and instead thought figuring out the origin was the answer.
To use your analogy, why would they think finding the bomb's location would stop the deaths of victims in need of medical attention?
Yes, we are now in the right time to explore the causes BUT MORE IMPORTANTLY to establish the protective measures NO MATTER WHAT origin a future pandemic may come from.
That's a far wiser and Efficient method. May the Creator protect those of us who understand this from the fear based minds of the rest.
