Notorious Doomsday soothsayer Harold Camping has now shifted the blame to God for his failed Doomsday prophecy on Oct. 21.

Camping had predicted that the World will end on May 21 and when it didn't happen, he revised the date to Oct. 21 and that also failed to materialize.

In an audio file posted on his Family Radio Web site on Monday, Camping said, We're living in a day when one problem follows another. And when it comes to trying to recognize the truth of prophecy, we're finding that it is very, very difficult.

There's one thing that we must remember. God is in charge of this whole business, and we are not. What God wants to tell us is his business, he said.

Amongst other things, I have been checking my notes more carefully than ever. And I do find that there is other language in the Bible that we still have to look at very carefully and will impinge upon this question very definitely, Camping added.

ABC News reports that a source close to the preacher said Camping has actually predicted the end of the world a whopping 12 times. His first prediction dates as far back as 1978.

Camping based his ludicrous theory on the story of the Biblical flood of Noah's times. He made some unexplainable calculations to conclude that the flood took place in 4990 B.C.

It is said in the Bible that Noah had been given seven days to prepare for the flood. Camping says the '7-day warning notice' has been in place and he has actually decoded it precisely. Camping says though, that instead of a 7-day warning, it's really been a 7,000-year-warning. He says that according to 2 Peter 3:8, With the Lord a day is like a thousand years, and a thousand years are like a day.

Seven thousand years after 4990 B.C. (the year of the Flood) is the year 2011 A.D. (our calendar), says Camping on his website. 4990 + 2011 - 1 = 7,000, he says, and calculates, One year must be subtracted in going from an Old Testament B.C. calendar date to a New Testament A.D. calendar date because the calendar does not have a year zero. 

And here's how he arrived exactly at the date: 'Amazingly, May 21, 2011 is the 17th day of the 2nd month of the Biblical calendar of our day. Remember, the flood waters also began on the 17th day of the 2nd month, in the year 4990 B.C.

However, when Doomsday failed to materialize, the followers were left in the lurch. They did not Rapture to heaven as promised and had exhausted their life's savings. When questioned about the moral responsibility to the followers, Camping deftly washed his hands off. He said he was not really responsible for anyone in particular.
