But what is new, and what makes this season's dig at Gobekli so climactic, is the quality of the latest finds - plus that mind-blowing thesis which links them to the Garden of Eden.

The thesis is this. Historians have long wondered if the Eden story is a folk memory, an allegory of the move from hunter-gathering to farming. Seen in this way, the Eden story describes how we moved from a life of relative leisure - literally picking fruit from the trees - to a harsher existence of ploughing and reaping.

And where did this change take place? Biologists now think the move to agriculture began in Kurdish Turkey. Einkorn wheat, a forerunner of the world's cereal species, has been genetically linked to here. Similarly, it now seems that wild pigs were first domesticated in Cayonu, just 60 miles from Gobekli.

This region also has Biblical connections, tying it closer to the

Eden narrative. Muslims believe that Sanliurfa, a nearby city, is the Old Testament city of Ur. Harran, a town down the road, is mentioned in Genesis twice.

Even the topography of Gobekli Tepe is 'correct'. The Bible describes rivers descending from Paradise. Gobekli Tepe sits in the 'fertile crescent' between the rivers Tigris and Euphrates. The Bible also mentions mountains surrounding Eden. From the brow of Gobekli's hills you can see the Taurus range.

But how does this intoxicating

notion link to the architecture of Gobekli, and those astonishing finds?

Klaus Schmidt (left) says: "Gobekli Tepe is staggeringly old. It dates from 10,000BC, before pottery and the wheel. By comparison, Stonehenge dates from 2,000BC. Our excavations also show it is not a domestic site, it is religious - the world's oldest temple. This site
