[W]heat is a genetic monster. A typical wheat variety is hexaploid—it has six copies of each gene, where most creatures have two. Its 21 chromosomes contain a massive 16 billion base pairs of DNA, 40 times as much as rice, six times as much as maize and five times as much as people. It is derived from three wild ancestral species in two separate mergers. The first took place in the Levant 10,000 years ago, the second near the Caspian Sea 2,000 years later. The result was a plant with extra-large seeds incapable of dispersal in the wild, dependent entirely on people to sow them. . . . People in what is now Syria had been subsisting happily on a diet of acorns, gazelles and grass seeds. The centuries of drought drove them to depend increasingly on wild grass seeds. Abruptly, soon after 11,000 years ago, they began to cultivate rye and chickpeas, then einkorn and emmer, two ancestors of wheat, and later barley. Soon cultivated grain was their staple food. It happened first in the Karacadag Mountains in south-eastern Turkey—it is only here that wild einkorn grass contains the identical genetic fingerprint of modern domesticated wheat. . . . Agriculture brought drudgery, subjugation and malnutrition, because unlike hunter-gatherers, farmers could eke out a living when times were bad. But at least that meant that they could survive. . . .Agriculture brought drudgery, subjugation and malnutrition, because unlike hunter-gatherers, farmers could eke out a living when times were bad. But at least that meant that they could survive. Population growth was now inevitable. Within a few generations, wheat farmers were on the march, displacing and overwhelming hunter-gatherers as they went, and bringing with them their distinct Indo-European language, of which Sanskrit and Irish are both descendants. By 5,000 years ago wheat had reached Ireland, Spain, Ethiopia and India. A millennium later it reached China: paddy rice was still thousands of years in the future.

Wheat brought civilization to the world and its discovery was at the heart of the Neolithic revolution, which is, not coincidentally, close in date to the purported date of Creation calculating by Biblical geneologies. Hunter-gatherers didn't leave written histories behind.
Who lives in the "garden of Eden" where agriculture was invented now? The Kurds.
