Are the Anunnaki in the Epic of Gilgamesh and the Nephilim in the Bible the same?

TL;DR:

There appears to be a connection between the Nephilim in the Bible and the Anunnaki in The Epic of Gilgamesh, but there is not enough information to know for certain. The Anunnaki and Nephilim show us commonalities in the worldview of the ancient world.

what does the bible say?

The Anunnaki are mythological deities of ancient Mesopotamia. They appear in the ancient poem The Epic of Gilgamesh and in other Sumerian cuneiform tablets. There are similarities between the Anunnaki of the Mesopotamian world and the Nephilim in the Bible, but the account in the Bible was not copied from The Epic of Gilgamesh. The same is true of the flood account. This reveals a common understanding or interpretation of common events in the ancient world. In both the Bible and The Epic of Gilgamesh, supernatural beings interact with men during the time of a great flood. Because of this, we can say there is perhaps a connection between the Nephilim and the Anunnaki, but there is not enough information to be certain.

from the old testament

The Nephilim in the Bible are mentioned in Genesis and Numbers. In the days before the flood, there was great wickedness on the earth (Genesis 6:5). Part of that wickedness was that something supernaturally wicked was also taking place on earth. Genesis 6:4 says, “The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown.”
The Nephilim were the offspring of the sons of God (Got Questions Ministries' interpretation is that these were fallen angelic beings or demons) and the daughters of men (Genesis 6:1–4).
The Nephilim are also mentioned when Caleb and the other leaders of Israel scouted the land of Canaan. In their report, they said, “There we saw the Nephilim (the sons of Anak, who come from the Nephilim), and we seemed to ourselves like grasshoppers, and so we seemed to them” (Numbers 13:33).
There are a number of similarities between accounts of the Anunnaki and the Nephilim mentioned in Scripture. The Anunnaki are chthonic deities— meaning they are associated with the underworld— who were said to be the offspring of Anu (the sky god) and a female called Ki. It is unclear from the mythology whether Ki was human or goddess, but since Ki has no cult of followers, it can be assumed she was a human female. This corresponds to the biblical account of the Nephilim.
Both the Bible and the Epic of Gilgamesh mention a global flood event. In the epic, a man named Utnapishtim is told by the god Enki (or Ea) to build a great big boat and put his relatives and baby animals into the ship. After twelve days, the boat comes to rest on Mount Nisir. He sends out a dove, and then a swallow, to search for dry land, and then a raven, which does not return—showing that it was safe to disembark. Utnapishtim then sets the animals free and makes a sacrifice to the gods. This story is similar to the biblical account of Noah, which occurs just after the story of the Nephilim in Genesis (Genesis 6:5—8:20).

from the new testament

It is possible that the Nephilim are mentioned in 2 Peter 2:4 and Jude 1:6.

implications for today

The similarities between the Anunnaki in the Epic of Gilgamesh and the Nephilim in the Bible should cause us to think about how we view ancient history. Just like with the hundreds of flood stories that exist, the similarities between the Anunnaki and Nephilim show us that there indeed was something significant that happened in the ancient Near East that impacted various cultures enough for them to record it and to pass down the stories. Their recounting of this event bolsters our faith as we seek to understand the context of the people living in that time and God’s character as He responded to what happened.

The truth we tell matters and impacts generations to come. Differences in what we tell will exist, but that does not change the truth. For example, we may remember an event a certain way or recount specifics of the event that were important to us. Another person may remember it differently or choose other details to retell, but what we have in common is that the event did happen. As Israel was commanded to pass on the truth (Deuteronomy 6:4–9), so we are called to share the truth with others.

understand

The Anunnaki are described in The Epic of Gilgamesh as underworld deities who were the offspring of a deity and a mortal woman.
The Nephilim are described in the Bible as offspring of fallen angels and mortal women.
We cannot know for certain if the Anunnaki and the Nephilim are the same, but there is enough evidence to postulate their connection and see that they’re likely referring to similar events and characters.

Some people believe the Anunnaki were extraterrestrials. There is no proof of this either in The Epic of Gilgamesh or in the Sumerian cuneiform tablets. There was something supernatural that occurred, but they are not aliens as in beings living on other planets.
