Here's a couple of more links:
This crater is also mentioned by geologist Robert Schoch in his 2003 book "Voyages of the Pyramid Builders" (p 223)
"The latter possibility is supported by the recent discovery of a two-mile-wide meteroritic crater in the Al'amarah region of southern Iraq, north of the confluence of the Tigris and Euphrates rivers. First identified on satellite images by Dr. Sharad Master, a geologist at the University of Witwatersrand in Johannesburg, South Africa, the crater occurs in geologically young sediments and may date to the circa 2400-2300 B.C. period. More research will be required to substantiate this date. According to Dr. Benny Peiser of John Moores University, Liverpool, craters dating to the same time period have been found in Argentina. All of this evidence fits with a bombardment of meterors and comet fragments during the second half of the third millennium B.C."
It is hard to imagine that anything man-made in the vacinity would have survived this impact. It then seems unlikely that this event could have occurred after the founding of Eridu. Consequently, it is also unlikely to have been associated with Noah's Flood, but possibly the flooding that preceded the time of Adam/Atum. One must further suspect that the impact crater actually was a source of attraction for the "gods" who chose to build the "first city" close by.
