Nogodnomasters said:The flood story does NOT appear in the original Gilgamish epic, it was added at a later date. Gilgamish simply builds a stele to ensure his immortality.
Thus Gilgamish's relationship to any flood and Nephilim was most likely manufactured by ancient authors.
The Epic of Gilgamesh consist of twelve tablets, the 12th being the tablet that scholars believe was added later because in the first 11 tablets a character name Enkidu dies and in the 12th he's alive again. Scholars think the 12th tablet was a sequel to the first 11 tablet story, Utnipishtim explains the events of the flood to Gilgamesh in tablet 11.
If you have a link or author that expresses a different viewpoint of the Epic of Gilgamesh please post it I would love to read it.
The whole issue with Gilgamesh is that he found out he was of "divine" blood, in ancient Mesopotamia that would have been the Anunnaki (those from Heaven to Earth came) who mated with Humans, for the Greeks that would have been the Olympic gods which also said to have mated with humans down the line to the Hebrew Torah which have the Nephilim (those from Heaven to Earth fell) or as popularly known as The Fallen Ones as who mated with humans.
The Sumerian depicted the Anunnaki allot of the times with wings, evolving through time to become the flying angels of the Bible. But the Sumerians never depicted them in flight with their wings being used for flight more like a decoration or rank identification sort of like how a military would clip wings on a soldier.
