“You have to understand, there will be nothing, nothing left,” Geryl told ABC News from his home in Antwerp, Belgium. “We will have to start an entire civilization from scratch.”

That’s because Geryl believes the world as we know it will end in 2012. He points to the ancient Mayan cyclical calendars, the longest of which last renewed itself approximately 5,125 years ago and is set to end again, supposedly with catastrophic consequences, in 2012. He speaks of the ancient Egyptians, who, he claims, saw 2012 as a year of great change too. And he points to science: NASA predicts a sharp increase in the number of sunspots and sun flares for 2012, he said, sure to cause electrical failures and satellite disruptions.

All this adds up, Geryl said, to unprecedented catastrophe. First, a polar reversal will cause the north to become the south and the sun to rise in the west. Shattering earthquakes, massive tidal waves and simultaneous volcanic eruptions will follow. Nuclear reactors will melt, buildings will crumble, and a cloud of volcanic dust will block out the sun for 40 years. Only the prepared will survive, Geryl said, and not even all of them.
