The person in charge of this is saying that the world is going to end on May 21st, because of a bogus calculation according to The Bible. In Genesis, God said to Noah (and I'm paraphrasing) that He will begin the flood after a week after warning Noah. Then a passage in the New Testament says (again, paraphrasing) that to The Lord, a day is like a thousand years. So, this guy has gotten the brilliant idea that the week from Genesis actually means 7000 years from the day God warned Noah, which is supposedly the 21st.
Obviously, this makes absolutely no sense. No, not in the conspiracy theory way, but more in the way where the creationists believe the world was created in what? 6000 years ago? So, doesn't add up. It defies logic, EVEN IN THEIR OWN MYTHOLOGY.
Also, to the people who are saying that this is some "crazy right-wing Christian thing" and talking about atheism and things... just because there's one crazy guy, it doesn't mean you can just generalize. This isn't a huge thing, just a bunch of very gullible and worried people taking some insane actions due to outrageously ridiculous logic. Religion and politics don't play a part on this too much (to me, these people seem to be using the system of religion to fulfill their own goals, which is really antithetical to the concept of religion). You can argue about the wrongs about the concept of religion, but let's not get out of hand.
But then again, I'm an agnostic, whose opinions don't matter on either sides, so... Shit.
Hope this helps, OP. Don't worry. The world won't end because of an angry god. It will end when the Andromedan galaxy collides with our own and slowly absorb the matter that makes up our own galaxy, our suns, our planets, our very own selves to fuel its everlasting and lifeless hunger. I...
That didn't help. Sorry.
