It's one of the most powerful and enduring myths ever created. The Garden of Eden. It is the very definition of paradise: a land of endless plenty where there is no work, no sorrow, no hunger and no disease. But could it be true? Did the Garden of Eden exist as a real place? The only clues to its whereabouts lie in the Bible, which states that the garden is the source of four major rivers: the Tigris, Euphrates and Pishon and Gihon. The sources of Tigris and Euphrates are easy to find, as they are up in the Torus mountains. However they are hundreds of miles apart. So the key to finding Eden would be to locate the other two rivers' sources. The trouble is no one has any idea where the Pishon and Gihon are. The names have long since fallen into disuse. One maverick scholar thinks he may have cracked the code. Professor Juris Zanis thinks he knows where Eden really was and why it really disappeared. To find the answer, Zarins took a multi disciplinary approach; using geology, anthropology, archaeology, linguistics and hydrology. Zarins started to look at the cultures who inhabited the area where the Tigris and Euphrates Meet: Southern Mesopotamia. He believes that the Sumerians who lived 7000 years ago created large-scale urban settlements: the world's first cities. Among their legends was a bountiful garden, a paradise called Dilmun. Dilmun sits on the East coast of Bahrain. Could this be the remnants of the Garden of Eden? Now he had to confirm the stories of the Sumerians using the latest land sat technology. This would give Zarins a "birds eye view" from space at the geology of the region, able to view the rock formations clearly both on land and underwater. Would it give him the final confirmation that he had found the fabled Garden of Eden?
