Was there really a flood over the whole earth?
The short answer
Yes, Genesis presents the flood in Noah's day as a real judgement that covered the earth as its people knew it and destroyed human and animal life outside the ark. The Hebrew text describes waters covering the high mountains and all flesh dying, Peter treats the event as history, and the honest open question among Christians is the flood's exact geographical extent, since the Hebrew word for earth can also mean land.
The fuller answer
The flood account fills Genesis 6 to 9 and is told as history woven into the book's genealogies, not as a parable set apart from them. God saw that human wickedness was great and that violence filled the earth, and he resolved to judge it with water. Noah, described as righteous and blameless among the people of his time, was told to build an ark, gather his family and animals of every kind, and did everything God commanded. The flood came, in the narrative's own dating, in the six hundredth year of Noah's life, and the waters rose for forty days of rain and far longer from the fountains of the deep.
This is the account of Noah. Noah was a righteous man, blameless in his generation; Noah walked with God.
Genesis 6:9 (BSB)
On extent, the passage should be quoted at the strength it actually carries. Genesis says the waters rose and covered the high mountains under the whole heaven, that every living creature on dry land outside the ark died, and that Noah's family alone survived to repopulate the earth. That is universal language. At the same time, the Hebrew word rendered earth, eretz, frequently means a land or region elsewhere in the Old Testament, and some Christian readers therefore understand a flood that covered the whole inhabited world known to its people, while others hold to a flood covering the entire planet. Both groups take Genesis as truthful history; they differ over the reach of its words.
Whoever sheds the blood of man, by man his blood will be shed; for in His own image God has made mankind.
Genesis 9:6 (BSB)
Other peoples of the ancient Near East told flood stories too, and they should be named for what they are: parallels, not proof in either direction. The Babylonian Epic of Gilgamesh, in its eleventh tablet, tells of a flood hero warned by a god, a boat, animals, birds released after the waters fell, and a sacrifice on a mountain. Similar flood traditions appear in other Mesopotamian texts older than the written Genesis. Those parallels show that flood memory was widespread in the world Genesis came from. They do not by themselves prove Genesis borrowed its account, nor do they prove the biblical flood happened; each account must be weighed on its own terms.
I have set My rainbow in the clouds, and it will be a sign of the covenant between Me and the earth.
Genesis 9:13 (BSB)
The New Testament weighs in on the event's reality. Peter, in 2 Peter 3, argues from the flood as a past world judgement to a coming judgement by fire, and treats scoffing at the one as of a piece with scoffing at the other. Jesus likewise spoke of the days of Noah and the flood coming on an unprepared generation as the pattern for his own return. After the waters fell, God made a covenant with Noah, with every living creature and with the earth itself, setting the rainbow as its sign, and that covenant, not geological argument, is where Genesis itself puts the weight: the God who judged is the God who promised never to judge that way again.
