To just expand on what I said. Outside the Bible, there is little evidence Judaism came from Sumer. Evidence is pointing to the idea that it was a Canaanite tribe, that later separated itself after Egypt started loosing power in the region. From what it looks like, they took a local tribal god and eventually made it into God.
There is no evidence to suggest that God is enlil. Even if it started off that way, which it most likely didn't, by the time Judaism developed into a monolatry, there is not doubt it was God, and not Enlil. Actually, even from the time that the decided to make themselves distinct from the other Canaanite tribes, God could not be seen as Enlil, especially as soon as the Jewish god started evolving.
Probably, fallingblood.
But you forget one thing.
It may not have gotten from the Sumerian religion itself, but it could have gotten it from the Old Babylonian or Middle Babylonian period. The Babylonian religion was quite widespread, and they have found fragments of Akkadian or Babylonian texts of the story of Gilgamesh as far as the Hittite Empire, Palestine and even in Egypt.
From my private studies of the Egyptian and Near Eastern myths, the Canaanite and Syrian god, El and Ba'al were most likely derived from the mixture of Babylonian gods.
El, "god", was mostly derived from a combination of Anu (Sumerian An, god of heaven), Enlil (god of earth and winds) and Ea (Sumerian Enki, god of the water). Enlil can also be written as Ellil, which seemed close enough to El or Il. The name means "Lord of the Winds". The Israelite also referred to their one god as El, just like the Canaanite/Syrian El or Il. And the name Elohim seemed to derive from El.
Ba'al means "lord", but he was called Hadad, god of thunder, and the Babylonian version of Hadad is Adad (Sumerian Ishkur), who was also the god of thunder.
Also some of the Canaanite gods found their way into Egypt, such as Ba'al, Reshep, Anat, Astarte, Baalat and Qadesh, brought in by the Semitic people known as the Hyksos.
So the Babylonian gods could have reached Canaan and Syria, very much the same way the Canaanite gods reached Egypt. Not only that. The worship of the goddess Ishtar (Sumerian Inanna) had reached Egypt at the time of Assyrian empire, probably in the 7th century BCE.
So there are no doubt a derivative of the Sumerian god(s) reached Canaan. Just as the Canaanite changed the Babylonian deities (Enlil and Ba'al) for their own religion, the early Judaism could have easily adapted the Canaanite gods to suit their one god, quite easily.
And from what I understand of Hebrew religion, Yahweh was not a name used until Moses' time, probably in 13th century BCE.
