This is about an upcoming PBS TV special that will air in Novemeber this year.
The Nova program will premiere Nov. 18. PBS presented a clip and a panel discussion at the summer tour of the Television Critics Association.
The program says the Bible was written in the sixth century BC and that hundreds of authors contributed.
"At least the first five books of the Bible come together during the Babylonian exile," says producer Gary Glassman.
The program challenges long-held beliefs. Abraham, Sarah and their offspring probably didn't exist, says Carol Meyers, a religion professor at Duke University.
"These stories are unlikely to represent real historical events, but rather there's some kernel of ancient experience in there which has survived and which helps give identity to the people at the time the Bible finally took shape centuries and centuries later," Meyers says.
