Have you ever read the short story "The Year of the Jackpot" by Robert Heinlein? If you are reading this... after everything has happened, then maybe you might be able to find a surviving copy; if not, it's basically a story about a man who notices weirdness happening worldwide, and statistically analyses it. His forecast, unfortunately, is proven right when the Sun starts to dim.
Things have been feeling a bit like that, recently.
There are always diseases, wars, phenomena; when it starts appearing like there's a pattern, no matter how marvellous you think the human mind's ability to see patterns, you do begin to worry.
I am not religious, I don't know if I believe anything anymore. Except I know that the Apocalypse comes, it will not be by the Hand of God, but by those people believing they are doing God's Work.
Not that there aren't plenty of ways for the world as we know it to end.
