America's Newsroom co-host Bill Hemmer stopped by Fox and Friends this morning to preview his upcoming Fox News Reporting special, "Countdown to Doomsday."

The special, which airs Wednesday at 9p ET, will take a look at the end of the Mayan calendar, which falls on 12.21.12 and debunk theories about the end of civilization.

Adam Housley explores the mystery of the Maya and why Doomsday has been pinned on them.

At the battlefield of Armageddon, Lauren Green investigates the Book of Revelation’s end times battle between Good and Evil and the belief that “second coming of Christ” is imminent.

Amy Kellogg discovers what the Maya shared with Neolithic builders of Stonehenge and with those who erected amazing megalithic monuments around the world.

"(The Mayan theory came from) the movement of the sun and how it aligns itself every 365 days on the winter solstice. And that's what they based everything on. It's a fascinating theory," said Hemmer.
