You can refer to the Book of Revelation in the Bible or, in popular culture, you can find them in the Left Behind series. What I’m referring to is the 7 signs of the apocalypse. Many people can name a few: the four horsemen, a great earthquake, the anti-Christ, etc., but The History Channel documents nearly everything in this near 2hr comprehensive documentary. Make no mistake, this documentary relies heavily on Biblical scripture, but ties in current events that indicate possible signs of the end of times drawing near.
