Yeah, the world is going to end in 2220. Everyone get their facts right!
Except that they also believed the world literally ended every 57 years and the last few weeks of each cycle was filled with terror because people weren't sure if they were going to be given another 57 years or not.
It doesn't matter if they're right. If they can't proove they're right, then they're wrong. No matter how right they may be.
