It's never happened and I doubt it ever will.
A giant meteor could hit the earth and wipe us all out,it can happen but when is a total unknown!
The millions that died in the 1918 "Spanish Flu" pandemic would be glad to here that! I personally had a Great-Grandfather and two Great-Uncles who died from that event.
I probably lost some distant ancestor eons ago from a meteor strike but..., that happens far less often!
"It's never happened and I doubt it ever will."
Ever considered reading some history? 1918, for instance?
