Zecharia Sitchin says he's willing to stake everything he's written about alien astronauts on DNA tests that could be performed on the 4,500-year-old remains of a high-ranking Sumerian woman. It's the latest - and possibly the last - cause celebre for a fringe celebrity.

The way Sitchin sees it, the long-dead woman's genome could contain the signature of the gods and demigods he's been talking about since 1976.

The 90-year-old Sitchin was born in the Soviet Union, grew up in Palestine and now lives in a New York apartment. He has written 14 books about way-out subjects, starting out with claims that a "12th planet" named Nibiru swung past Earth thousands of years ago and dropped off alien visitors who were looked upon as gods by Middle Eastern cultures. Sitchin says these aliens were the Annunaki mentioned in Sumerian scriptures, and the Nephilim mentioned in the Bible.

Needless to say, Sitchin's ideas - like those of another ancient-astronaut author, Erich von Däniken - have been roundly scorned by the scientific community. But now Sitchin is asking that very community to help him with the mystery of Queen Puabi.
