Why the similarities are noticed
The Bible was written among real peoples and nations, not in a cultural vacuum. Ancient Mesopotamian writings include stories of a great flood, and other cultures told accounts of how the world began. So it is understandable that readers notice echoes between those stories and Genesis.
But shared features do not settle the question. Different people can preserve memories of a real event, retell common questions, or use familiar story forms while meaning very different things by them. A flood, a boat, or a creation account is not enough on its own to show that one text simply copied another.
Genesis opens with a strikingly simple claim: the universe begins because God creates it. The chapter does not present the world as the accidental result of battles among rival gods. It introduces one God who stands above all He has made (Genesis 1:1).
In the beginning God created the heaven and the earth.
The differences matter
When stories are compared closely, the Bible's differences are often more important than the surface similarities. In Genesis, people bear God's image and are given a responsible place in creation (Genesis 1:26-27). Human life has dignity because it comes from God, not because people exist merely to serve the needs of unpredictable deities.
The flood account makes a similar point. Genesis does not describe God acting on a whim. It connects the coming judgement with widespread human evil, while also showing Noah as a man who walked faithfully with God (Genesis 6:5, Genesis 6:9). The story is morally serious, not simply an adventure about surviving a disaster.
After the flood, God receives Noah's offering and promises the ongoing order of the earth. He then gives the rainbow as the sign of His covenant with living creatures (Genesis 8:20-22, Genesis 9:12-13). Mercy and commitment shape the ending.
And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations: I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.
Did biblical writers use familiar language?
They did write for people who knew the languages, images, and beliefs of their own world. That is what communication looks like. Scripture does not need to sound foreign to its first hearers in order to tell the truth.
Yet using familiar surroundings is different from borrowing another religion's message. Again and again, the Bible challenges the worship of created things and calls people to honour the Creator instead. Paul makes this contrast clearly when he describes people turning from the Creator to created things (Romans 1:25).
The Bible's central storyline also holds together from beginning to end: God creates, people rebel, God judges sin, and God works to bless and rescue. Christians see that story reaching its centre in Jesus, through whom all things were made and in whom God makes Himself known (John 1:1-3, John 1:14).
Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
A wise way to explore the question
You do not have to be afraid of the question. Read Genesis for itself before relying on quick comparisons online. Ask what the passage says about God, people, evil, worship, judgement, and hope. Those questions reveal the Bible's own purpose.
Christians differ on how they explain every historical relationship between biblical accounts and ancient writings. Some see shared memories of ancient events, while others stress that biblical authors reshaped familiar material to correct false ideas. But both approaches can recognise the Bible's distinctive witness to the one God who speaks, judges rightly, and keeps covenant.
Start with Genesis 1 and Genesis 6 to 9, then keep reading. The Bible invites examination, not blind panic. Its opening declaration is not that the gods fought their way into existence, but that God was there before the world and made it.
