Little known prophet of doom, Harold Camping said he was 100 percent certain that Jesus will return to earth on May 21, 2011 – this Saturday, mark the end of the world as we know it.

Camping estimates 200 million will be raptured, while the remaining nearly 7 billion face a grisly fate – crushed in the quake, burned by sulfur, turned into pillars of salt, etc.

As why the 90-year old preacher and author predicted May 21 as the ‘Day’, he said, from his calculation May 21 is exactly 7,000 years from the date of the Noah’s Ark flood.

In his book “Time Has an End,” Camping writes. “The year 391 B.C. is the year when the Old Testament was finished, and 2,011 + 391 – 1 = 2,401, or 7 x 7 x 7 x 7.”

Camping believes the Gay Pride and same-sex marriage as partly the reasons for the end of the world. Camping says God will punish America and the rest of the world for Gay Pride and same-sex marriages, just as Sodom and Gomorrah were punished with fire and brimstone in the Old Testament.

More than a decade ago, Camping predicts the end of the world would take place in September 1994? He said the reason why it didn’t happen then was because of the book in which he made the prediction was titled “1994?”. The question mark makes all the difference.

Harold Camping is the owner and president of Family Radio, a religious network based in California. He built the media empire in 1958, proposing one thing: the diffusion of the Campsite view of Christianity.

Camping has been warning of the end of the world in the family radio for some time. It is said that two things will happen on May 21, 2011:

1) A major earthquake that left open all the graves, the resurrection of all believers and
2) All non-believers will be “thrown upon the ground to be shamed” says his website.
