Some say the Enuma Elish was a copy of a Sumerian text containing the roots of the biblical creation. They think it preceded the Genesis account of creation and they also think the Genesis account was simply a copy of it. However, there are many problems with these assertions.
In 1845, an archaeologist found seven, stone tablets in some ancient ruins in Assyria; specifically, ancient Nineveh. These tablets contained a Babylonian, creation account written in Akkadian cuneiform. It was published in 1876 and named the Enuma Elish after the first two words, which mean "when above."
There are a few, vague similarities with the Genesis account. However, there are countless other things mentioned such as several gods, the death of a god, someone being created from a god's blood, etc. . . .
These tablets were found in the library of the Assyrian king Asshurbanapal. They are dated to the 12th century B.C. Some believe they are based on an older, Sumerian version of the poem from approximately 1800 B.C.; which was the time of Abraham and Hammurabi. Consequently, the real question is this: Did the alleged, Sumerian version pre-date the biblical account of creation and if it did, was the biblical account created from it?
The easiest way to find this answer is to discover when these stories were written. The events in the first five books of the Bible, often called the Pentateuch, pre-date the alleged, Sumerian text and were essentially written by Moses. Moses lived around 1500 B.C. There are a great number of reasons to believe Moses wrote 99% of the Pentateuch (including Genesis) and some of these reasons include the following.
1) In Exodus 17:14 and 34:27, we read that the Lord told Moses to write.
2) In Exodus 24:4, Numbers 33:2, Deuteronomy 31:9, 31:22, and Deuteronomy 32 we read that Moses wrote.
3) The New Testament affirms, in Luke 20:28, that Moses wrote in the Pentateuch. It reads, "Saying, Master, Moses wrote unto us, If any man's brother die, having a wife, and he die without children, that his brother should take his wife, and raise up seed unto his brother."
4) Later in biblical history, we read that there was a "Book of Moses." See Joshua 1:7 and 8, 2 Chronicles 25:4, Ezra 6:18, and Nehemiah 13:1.
5) Jesus and the early church attributed the Torah to Moses. See Matthew 19:7, 22:24, Mark 7:10, 12:26, John 1:17, 5:46, and 7:23.
6) The early Jewish and Christian tradition is virtually unanimous in ascribing Genesis through Deuteronomy to Moses. See Ecclesiasticus 24:23, Philo, Josephus, the Mishnah, and the Talmud.
Now, we have seen that the first five books of the Bible (including the creation account) were penned by Moses near 1500 B.C. This clearly predates even a late dating of the Enuma Elish. Therefore, one of our questions have been answered.
