Every 100 years or so a virus comes through and wipes out the population. It's a very well known event. Goes back since the beginning of our written history. Had the bubonic plague, typhoid, cholera, smallpox, spanish flu, covid19, and countless others.
So you don't believe in history? You must be a real smooth brain to feel that way. I'm sorry your life is so miserable you have to spread misinformation anonymously on the internet to make yourself feel better. But hey, if what you believe is true then none of it matters, right?
