Doomsday !
The Bulletin of the Atomic Scientists sets the hands of the Doomsday Clock and that setting has changed many times since 1947.
Does it scare you to know that a group of supposedly educated individuals thinks we're closer to annihilating ourselves?
Does your Faith have anything to say about the End of the World?
Why have all the Major Faiths in recorded history included in their Scriptures a reference to the end of things as we know them? They've even predicted (symbolically) a time when the "End" will arrive. Even, in some cases, given hints that certain individuals have interpreted as definite dates for human, earthly annihilation...
If you don't have first hand info on what various Faiths have claimed, the Doomsday Guide is an interesting place to begin an investigation.
