Answer:
The story of the flood can be found in many ancient nations' mythology. Here will be given some of the striking similarities between versions of this story from The Epic of Gilgamesh and from The Bible.
Firstly, the flood was sent as a punishment for people's sins and misbehavior. One man was informed about the disaster; in The Bible it was Noah, in the Gilgamesh it was Utnapishtim. Both men built an ark containing many compartments and only one door. All animal species were brought on the boat. Although the flood didn't last the same amount of time in the two stories, its consequences were the same: the water covered the ground and the ark passengers were the only ones left alive.
Also, both boats landed on a mountain peak and both protagonists sent birds to check for nearby land.
Finally, both man offered sacrifice after the flood was over.
Of course, these are only some of the biggest similarities between the two stories. After more careful reading of the stories, one will surely be able to find few similarities more.
I hope this helped.
