In The Epic of Gilgamesh and The Book of Genesis, there are a couple of similarities that they both have in common. For example, they both discussed the story about the God(s) sending the flood to the city in order to destroy the whole civilization, while leaving some of righteous humans alive: Uta-napishti from The Epic of Gilgamesh and Noah from The Book of Genesis. Despite the difference in their backstory, these two characters are both given the same role as the one who tries to recreate their own society with animals and resources that they brought with on the Ark. Another similarity is that they both send out ravens outside of the Ark to make sure the water is subsided and the land is dried after the flood.
Although I am not certain,
