Gilgamesh wrote in in cuneiform
The Epic of Gilgamesh was preserved on clay tablets written in cuneiform script. These tablets were discovered in the ruins of the library of Assyrian King Ashurbanipal in the 19th century. The discovery of multiple copies of the epic allowed scholars to piece together and translate the complete story.
Epic of Gilgamesh
The account of Noah's Flood has some similarities to the Gilgamesh story. This is thought to be due to the oral transmission of the account which became distorted over time while Noah's Flood account in the Old Testament was recorded earlier in writing and so is better preserved.
Certainly the story of Noah's Flood is remarkably similar to the Flood story of Umapishtim in the much older Sumerian Epic of Gilgamesh. On that evidence, the Epic of Gilgamesh is the most likely source for the story of Noah's Flood.

He carved the story of his journey on a stone tablet. In some translations, the Epic of Gilgamesh is carved on a stone of Lapis Lazuli.
The tale other than Gilgamesh's journey is the Flood Story. This is the story of Utnapishtim and how he survived the flood the gods sent.
There is a very close correlation between the version of the flood story preserved in the standard version of Gilgamesh and the biblical flood story in Genesis. It is generally accepted by scholars and historians that the Gilgamesh epic was written first. This does not automatically imply direct dependence - both could derive from an earlier version of the story for example. The most likely explanation, however, is that Genesis polemically modifies the Mesopotamian tale to present the story in a unique way. Typically, the bible introduces a moralistic perspective - God destroys humanity because of wickedness - and is monotheistic. One scholar has also suggested that the story of Nebuchadnezaar's madness in Daniel chapter four draws on elements found in the description of Enkidu as "wild man" in the early sections of Gilgamesh.
