Do you see matches between the Epic of Gilgamesh to other ancient literature?

The Epic of Gilamesh central theme is the myth of the deluge. This myth has been repeated troughout different literatures in variations, but it is most famous for being featured in the Genesis. The book of Genesis, however, was written after Gilamesh. The explanation is trifold  a) Genesis took the idea from Gilamesh  b) Gilamesh and Genesis are to be read together or one is an extention of the other, and c) both stories come from yet another protostory.

The deluge story, as said previously, has been told in several ancient texts, which puts into doubt the reliability of many books considered "sacred". An example of this is the story of Noah's Ark.

In the link I provided, you will be surprised to find that, in nearly every major country and continent there is a Flood story, told in different versions. Yet, universally, it is understood that the closest resemblance to Gilamesh is the story of Noah.
