Lost Civilization under Persian Gulf?

75,000 to 100,000 years ago, underneath the Persian Gulf, a once fertile landmass the size of Great Britain, may have supported the earliest human life. It then began to shrink due to flooding and was overtaken by the Indian Ocean until complete disappearance about 8,00 years ago. This article which I found on Yahoo!, stirs much debate amongst scientists over when humans exited Africa, which goes as far back as 125,000 years back or as early as 60,000 years back. Scientists also wonder which human inhabited this lost civilization. According to the article "Given the presence of Neanderthal communities in the upper reaches of the Tigris and Euphrates River, as well as in the eastern Mediterranean region, this may very well have been the contact zone between moderns and Neanderthals".  The location of this settlement would have been an ideal location, providing refuge from the surrounding deserts, and fresh water from the Tigris, Euphrates, Karun and Wadi Baton Rivers. The article also states: "These settlements boast well-built, permanent stone houses, long-distance trade networks, elaborately decorated pottery, domesticated animals, and even evidence for one of the oldest boats in the world."
