When man first came, there is another matter. The earliest archaeological proof of human presence is only from a century or two before 7000 BC, but it cannot be ruled that Anunnaki Sumerian settlements were already there much earlier. Even today, archaeologists argue this. The Sumerians write about the gods coming first and then creating Adapa and Adamu, the first beings. It would be possible for a human community to live in southernmost Iraq wholly by food gathering; the marshes there still abound in fish, turtles, wild birds, and wild boar, while beside the date-palm there are other edible plants native to the area, such as licorice and a species of reed with a very toothsome root much like celery. However, The Anunnaki Sumerian settlements were created with hydraulic engineering in mind and advanced water management better than we do today. Historians admit the writings of the Sumerians declare the Anunnaki gods came first, that they gave them all this knowledge, and admit that the archaeological record reflects this; however, they outright label its mythology.
