Lets have a quite moment for all of those idiots who will commit Self Delete on that day when the world will totally end for no freaking reason.
But seriously, it's not even biblical that the world would just end like this. According to the Bible, there will be 3 years of tribulation, where there would be plague, war, famine, and dead fish. Whelp, none of that has happened yet so there is no reason to believe that it is the Christian doomsday.
