MEXICO CITY (AP) - Apolinario Chile Pixtun is tired of being bombarded with frantic questions about the Mayan calendar supposedly "running out" on Dec. 21, 2012. After all, it's not the end of the world.

Or is it?

Definitely not, the Mayan Indian elder insists. "I came back from England last year and, man, they had me fed up with this stuff."

It can only get worse for him. Next month Hollywood's "2012" opens in cinemas, featuring earthquakes, meteor showers and a tsunami dumping an aircraft carrier on the White House.

At Cornell University, Ann Martin, who runs the "Curious? Ask an Astronomer" Web site, says people are scared.

"It's too bad that we're getting e-mails from fourth-graders who are saying that they're too young to die," Martin said. "We had a mother of two young children who was afraid she wouldn't live to see them grow up."

Chile Pixtun, a Guatemalan, says the doomsday theories spring from Western, not Mayan ideas.

A significant time period for the Mayas does end on the date, and enthusiasts have found a series of astronomical alignments they say coincide in 2012, including one that happens roughly only once every 25,800 years.

But most archaeologists, astronomers and Maya say the only thing likely to hit Earth is a meteor shower of New Age philosophy, pop astronomy, Internet doomsday rumors and TV specials such as one on the History Channel which mixes "predictions" from Nostradamus and the Mayas and asks: "Is 2012 the year the cosmic clock finally winds down to zero days, zero hope?"

It may sound all too much like other doomsday scenarios of recent decades - the 1987 Harmonic Convergence, the Jupiter Effect or "Planet X." But this one has some grains of archaeological basis.
