Noah's Flood Revisited: New Depths of Insight from Science and Scripture

by Hugh Ross

Is Noah’s catastrophic flood a myth, a moral dilemma, or a misunderstood historical event?

For centuries, the biblical account of Noah’s flood has sparked controversy. Some reject it as myth, while others struggle to reconcile it with a loving God. But what if the real problem isn’t the flood itself, but how we’ve misunderstood it?

In Noah’s Flood Revisited, Reasons to Believe founder and astrophysicist Hugh Ross uncovers fresh insights from both Scripture and science, showing how recent discoveries illuminate the historical reality of the flood—and why it matters today. With clarity and compassion, Ross dismantles misconceptions and reveals truth that strengthens both faith and reason.

Prepare to see Noah’s flood in a whole new light.

The author rejects the timelines that have been deduced from the "begats" of the Bible. He believes that the geological record simply doesn't support a world that is less than 10,000 years old. In what I would have considered a paradox only a few years ago, he also accepts that the Bible is true and makes an attempt to reconcile the two versions of human history. At one point, I would have considered it impossible - one or the other must be true, and the other false. They are mutually exclusive. But now I'm not so sure.

After all, IMO, the Bible doesn't set out to tell us human history. It sets out to tell us how God has worked in human history. If the Bible doesn't meet modern definitions of history, well, that's not the Bible's fault. So, I kept an open mind in listening to the audiobook.

One important point is that the flood has become a stand-in for proof of the Biblical account of creation. If the Biblical flood story can be "proven" to be true, then the Biblical account of Creation must be true. After all, the creation account is very difficult to prove. The Flood becomes a proxy. The author urges that they be considered separately.

Defenders of the Biblical narrative are on shaky ground when we conflate the two stories. After all, perhaps the flood wasn't exactly as we believe. And if that is the case, does that mean that I have to give up belief in God who created the world and humans? I don't believe so. Both stories need to be evaluated on their own merits.

The author reviews quite a bit of data that questions the idea of a worldwide flood that generated all of the geological formations that we know today. For example, he calculates that there could not have been enough biomass on earth at the time of the flood to generate all of the oil, gas, and coal deposits that we have today. An interesting argument, IMO.

The author believes that the flood as relayed in the Bible occurred during the last of the rapid ice melts that occurred during the last glacial period, approximately 40,000 years ago. He believes Noah lived in the Persian Gulf, which had much lower sea levels than we have today, and survived the flood by building the ark. The ark was necessary because humanity was so violent and wicked that Noah would not have been able to simply move to higher ground without being murdered.

One proof of this belief is the flood stories shared by people who live all over the earth. These stories become increasingly fantastic the further away one moves geographically from the Middle East, and the less related the language is from Middle Eastern languages. He believes this supports the idea that all people share this event and didn't dispurse as God instructed until after the Tower of Babel. He goes so far as to point out that modern humans did not reach Australia as early as claimed. (Additionally, he points out that popular news stories about dating frequently cite the earliest possible date without pointing out the margin of error, which is often very significant).

I found the ideas interesting and compelling. I would have appreciated more proof on why I should accept modern geology. The author appears to me to just accept it.

One point the author doesn't make is that people often wonder what kind of God would only show up after 100 millennia (give or take) of human history? Where has He been all this time? A counterpoint I can think of is to point out that only in the last few thousand years of human history has anything happened worth recording! Everything we can consider to have achieved as humans has all occurred recently in human history! Maybe we couldn't achieve anything relevant until God showed up! I'm grateful he did.

So read the book. Get some new ideas!

Maybe Not So Embarrassing After All

I have a strong and inquisitive faith, and an abiding respect for God’s revelation in His two books: Scripture and nature. Just as Einstein rejected the notion of God playing dice, I reject the notions that His creation only appears to be 13.8 billion years old and that the history of earth and humankind extends only millennia. I do not believe that God creates illusions or deceptions. Hence, the story of Noah and the Flood has been a conundrum, and nearly an embarrassment. I mostly have avoided its claims and rested on its theological revelation. In other words, I have doubted, which for me is very uncomfortable.
Then, along comes Hugh Ross, a Christian and accomplished scientist whom I have long trusted and sought out for the reconciliation between science and Scripture, and this fascinating book, “Noah’s Flood Revisited.” At last, explanations that are not simply plausible, but rather based on a thorough examination of the facts, scientific and Scriptural. He compromises on neither and makes a sturdy case for the historicity of the Flood. Maybe this remarkable episode in Scripture actually has its basis in history. Maybe it’s not a myth. Maybe it’s not so embarrassing after all. Maybe I should have been doubting my own understanding more and God’s revelation less. Thanks, Hugh Ross, for helping me in my unbelief and hubris.

Few events in ancient history generate controversy like Noah's Flood. With over 300 flood accounts in cultures worldwide, it's hard to dismiss. Sadly, the loudest voices are frequently people who have never studied what the Scriptures say, or who take the Scriptures word for word in their own language without studying the Hebrew in context. There are plenty of questions to ask. Was the Flood a myth? An allegory? A misunderstood historical event? A moral dilemma? How much of Earth was covered by water? How many animals went on the ark? What does DNA say about humanity going through a bottleneck and then spreading rapidly? How much biomass does it take to make fossils, oil and natural gas? When were the continents formed, and when did they split apart? This book takes a hard, literal look at what the Scriptures actually say, and then adds more truth from science. The conclusions are well-researched, and make sense both Scripturally and scientifically. Definitely worth reading.

What a delightful intersection of the Bible and science! Author Hugh Ross shows his chops as an astrophysicist as he applies the scientific method to Noah's flood.

Dr. Ross also shows his ability as a Biblical apologist as he carefully examines the Hebrew words describing the flood, showing that it was a flood local to the Middle East, and not worldwide.

Among the scientific finding Dr. Ross documents is that the timeframe of the flood is limited to 45,000 to 100,000 years ago. Another important teaching is the difference between statistical error and systemic error in date estimates.

Overall, the book should interest anyone who wishes to reconcile the Bible with science, or those who think it's impossible.

If young earthers actually read and thought about the facts presented in this book they would have difficulty in believing the young earth idea. Makes a good case that young earth is not really a good interpretation of biblical inerrancy. If you have to negate just about everything in science to support the young earth but the Bible supports that science then it is obvious that something is wrong with the interpretation.

Well researched and explained!

Hugh does a great job at explaining the reliability of Scripture, by showing how the revelation of nature and of scripture speak God’s truth, when both are properly interpreted. He does a great job at dismantling the teaching from the YEC views, though they try to give “scientific” explanations for their interpretation it quickly shows it can’t possibly hold water. A great read!

Great insight into proving that Noah's flood was not global. A total fallacy because would need 4X the amount of water above, below, or frozen on the earth, in order to inundate the planet. It was a "worldwide" flood only through the eyes of Noah. He is the person the story is being told through. It was not through the eyes God but through his servant that we see the story told.

[Carey Smoak · Rating 4 out of 5]

A valuable resource for people who want to correctly understand Noah's Ark.

Fascinating read. Classic Ross. Very well researched. Really made me think about the plausibility of a flood that covered "the known world" but not the entire globe.
