@Olivier5,
The deluge was a Sumerian myth, as I explained. The Sumerians themselves dated it to 35000 BC or thereabout, based on Sumerian king lists of old. These lists typically begin with
antediluvian rulers .
The ascribed reign lengths are impossibly long, not unlike biblical patriarchs. But locations of the kingship gives a clue. Kingship was seen as handed down by the gods and could be transferred from one city to another, reflecting perceived hegemony in the region.
Quote:Rulership which from heaven descended:
At Eridu rulership (began).
At Eridu Alulim was king.
He ruled 28800 years.
Alagar ruled 36000 years.
Two kings.
64800 years they ruled.

The rulership passed to Bad-tibira.
At Bad-tibira Enmenluanna ruled 43200 years.

Five cities, eight kings.

Then the Flood came (upon the Land).
After the Flood had come,
The rulership descended from heaven.

Archeologists say that Eridu -- perhaps the earliest city in the world -- was founded c. 5400 BC, close to the Persian Gulf. The locations and precise dates of foundation of Bad-tibira and Larak, the second and third cities to exercise kingship in Sumer according to the king liust, are unknown. The earliest excavated levels at Shuruppak (modern Tell Fara in southern Iraq), and Sippar (modern Tell Abu Habbahnear 30 km southwest of Baghdad) date to about 3000 BC, but the sites have been poorly studied and older horizons might exist. Kish, the first city to rule Sumer after the flood, was founded in approximately 3100 BC according to wikipedia.
So the Sumerian king lists would place the deluge around 3000 BC, give or take a few hundred years. This corresponds with the end of the "Uruk period", an early neolithic urban culture in Mesopotamia (3100 BC), but it also allegedly matches the Piora Oscillation, an abrupt cold and wet period generally dated c. 3200 to 2900 BC. During this period the surface of the Dead Sea rose nearly 100 meters, then receded to a more usual level.
A few commentators have associated the climate changes of this period with the floods of the Gilgamesh epic.
