Yeah...he seemed to miss one important detail...and one that I think is more and more relative now that we have the science to kinda' see it coming...Revelations mentions a giant meteor crashing into the earth, poisoning the waters of the world with worm-wood (the stuff that made REAL Absinth Illegal)...a bunch of people doped up on worm-wood=zombie apocalypse. But then again, it could be a rogue meteor that we don't see coming (they're still finding meteors that come close to Terra that have previously been unknown).
Also, towards the end, His prophets (Assumed to be Moses and Ezekial) will walk the earth, warning the inhabitants, and when they are (presumably) killed, there bodies will lie in the streets for 3-Days.
But, bless his heart, this guy's a wack job if there ever was one...senile for sure.
Religious or not, the "Revelation of John" is a good read. Also, the movie "The Seventh Sign" (Old school Demi Moore) is a good flick to check out.
I had "I'm going down" playing by The Boss...
