Historians believe that the Black Death was worse than the Spanish flu. Fewer people died overall because there were fewer people on the planet. It took over 200 years for the population to recover.
Nothing like what’s coming in a few decades - near the end of the century IMO. In 3 1/2 years half of the earth will be dead. In the last 3 1/2 years the whole earth will be dead except for a handful of Jews hiding in the mountains of Jordan (Petra). That will be AFTER Jesus comes to take his own outta here.
We ain’t seen nuttin yet.
