According to a lot of doomsday sayers, we should have experienced the end of the world or an apocalypse dozens of times so far. Well it hasn’t happened yet, no matter how many sources they provided to prove them right. Their facts are normally based on an omnipotent being directly communicating with them or they have deciphered the date from a book over 2,000 years old.
Every time there has been a date declared for the end of the world, there have been followers that believe them. They quit their jobs, give up all their possessions, say goodbye to their loved ones and wait. Every time, without fail, the world has remained and the prediction turns out false. There have been cults which have had their members drink or eat something which kills them. Usually the reason is so that they can ascend, arrive at a new planet, or even board a space ship.
The only people even remotely close to predicting the end of the world are scientists in charge of updating a symbolic clock called the doomsday clock. The clock is actually based around the possibility of a global disaster, like nuclear war or irreversible climate change. It is measured in minutes and the closer to midnight the clock approaches, the closer we are to a devastating event happening.
The end of the world will eventually come, which could be by disease, an asteroid, or even because of our own stupidity.
