Around 4400-4300 years BC in southern Iraq, on the banks of Tigris and Euphrates rivers was Ubaid agricultural culture, the development of which has led to the addition of the Sumerian civilization.

It will shed light on the riddle of the origin of Ubaid culture, which is the ancestor of the Sumerian culture

Glory to the Sumerians and their towns, such as Uruk, Ur, Lagash, has reached our days. The Sumerians created one of the greatest achievements of human genius: at the turn 4 and 3 millennia Sumerians transmited the human voice by means of signs, and thus create the first in the history of mankind writing system. Sumerian architects invented the arch. The Sumerians domesticated chickens, created the first Agrotechnical calendar, the first hatchery in the world, the world's first forest protection plantations, the first library catalog, the Sumerians wrote the world's first medical prescriptions.

In all excavations pottery is the bulk of the finds. It will shed light on the riddle of the origin of Ubaid culture, which is the ancestor of the Sumerian culture. After comparing all the known data on the Ubaid culture, the researchers came to the conclusion that Ubaid pottery culture has a local origin. Obviously, the first settlers brought here Ubaid pottery style and forms of his native country. Where is it located? The only place where pottery of a similar type was discovered - is Elam, a mountainous region located in the south-west of modern Iran. It was here in the Euphrates valley 6000 years ago, came to an agricultural people, who owned the art of fine stone processing, stone hoes to cultivate the land, the grain was ground on stone mortars and hand mill; and do pruning of baked clay. These people are about 4400-4300 years BC established in southern Iraq Ubaid culture, the proliferation of which begins a new era, which led to the Sumerian civilization.

Most of all, the establishment of Ubaid contributed to the rise of trade and developed agriculture.

But the most surprising finding of archeologists was the fact that the Ubaid culture destroyed... the deluge! The Bible says that during the Flood waters rose to eight meters. Following the excavation it was found that it was true: the maximum thickness of the layer of silt brought by the flood comes to three and a half meters, ie water should rise by at least seven and a half meters. During this flood on a flat plain of Mesopotamia under the water was a large space - 500 kilometers in length and 150 in width. Few city Ubaid, located on an artificial hill, survived after such a disaster. Of course, it was not the Flood, but only in the flood valley of the Tigris and Euphrates rivers, inundating populated areas Ubaid between the mountains and the desert. But for those who lived here, the valley was the whole world. Most of the inhabitants of the valley, probably killed, and only a few residents Ubaid struck terror lived to see the day when the raging waters finally began to recede. And if at the same time some family - for example, Noah - managed to escape by boat, but this, too, is no surprise. After all, in the legend is known to always have a rational core.
