How similar are Flood stories from other ancient near east sources, and why suppose these could pose any sort of problem?

The issues here are very similar to those mentioned above, with respect to the creation of the universe, the creation of Adam, and the Garden. But the similarities between Genesis 6-8 and at least two ancient Mesopotamian sources—the Atrahasis and the story of Utnapishtim in Gilgamesh—are truly striking. They are not merely accounts of a great flood. They are accounts of a world-ending universal flood, created by the gods to destroy man, with one man singled out for salvation, being instructed to build an ark to specific dimensions and to populate it with animals. In the Utnapishtim story, he even releases different birds to determine whether it is safe to venture forth after the flood; and then he sacrifices to the gods. The reason this could pose a problem is that Bible-believing Christians and Jews take the Noah story seriously, as revealing God’s master plan, one that is discussed and incorporated into the rest of the Bible narrative. The similarity to ancient pagan sources suggests thatthe Noah story might have had some pagan source. If it did, the narrative is false.
