Shepseskaf the Cool said:
"There is no mention of moses whatsover in the Summerian king list."
Sorry, Shepseskaf, I didn't make myself clear. The legend of King Sargon closely follows the narrative of the Moses story, and it is accepted that Sargon preceded any historical dating of the biblical Moses. So perhaps the Moses story is derived from that.
Here is one biographical entry for Sargon:
"There are many legends surrounding the birth and upbringing of Sargon, though they probably have varying degrees of truth. When the events from the legends are combined, we see that Sargon’s rise to emperor was a huge accomplishment. While the identity of his father is not clearly known, the legend states that his mother was a temple priestess. Giving birth to him in secret and setting him in a basket to float, she abandoned him to the Euphrates river. Akki, a gardener, rescued him from the river and raised him. After working as a gardener for Akki, Sargon rose to the position of cup-bearer to Ur-Zababa, the king of Kish."
And Wikipedia has this to say:
A Neo-Assyrian text from the seventh century BC purporting to be Sargon's autobiography asserts that the great king was the illegitimate son of a priestess. In the Neo-Assyrian account Sargon's birth and his early childhood are described thus:
“ My mother was a high priestess, my father I knew not. The brothers of my father loved the hills. My city is Azupiranu, which is situated on the banks of the Euphrates. My high priestess mother conceived me, in secret she bore me. She set me in a basket of rushes, with bitumen she sealed my lid. She cast me into the river which rose over me. The river bore me up and carried me to Akki, the drawer of water. Akki, the drawer of water, took me as his son and reared me. Akki, the drawer of water, appointed me as his gardener. While I was a gardener, Ishtar granted me her love, and for four and […] years I exercised kingship. ”
The image of Sargon as a castaway set adrift on a river resembles the better-known birth narrative of Moses. Scholars such as Joseph Campbell and Otto Rank have compared the 7th century BC Sargon account with the obscure births of other heroic figures from history and mythology, including Karna, Oedipus, Paris, Telephus, Semiramis, Perseus, Romulus, Gilgamesh, Cyrus, Jesus, and others.
Hope this makes my reply clearer.
