The Creation Podcast: Episode 117
Title: Creatures Lived Longer Before the Flood!
Host: Mary Claire (Institute for Creation Research)
Guest: Dr. Jake Hebert, Physicist – ICR Scientist
Date: February 24, 2026
Overview
This episode of The Creation Podcast explores the idea—rooted in a literal reading of Genesis—that both humans and animals lived much longer lifespans before the biblical Flood. Host Mary Claire is joined by ICR physicist Dr. Jake Hebert, who shares research and fossil evidence supporting pre-Flood longevity. The discussion spans fossil birds, dinosaurs, and living creatures, focusing on maturation rates, growth rings, and innovative new paleontological studies. The episode underscores the claim that science is increasingly confirming the Biblical narrative of early life on Earth.
Key Discussion Points & Insights
1. Pre-Flood Longevity: Biblical Roots & Biological Logic
- Literal View: Genesis describes pre-flood humans living for centuries, presented as ordinary, not supernatural.
- Applicability to Animals:
“If you assume that the human longevity was not supernatural... you're almost forced to conclude that the animals also would have experienced extreme longevity." – Dr. Hebert [03:07]
- Any biological or environmental reason for long human lifespans would apply to animals in the same world.
Mechanisms Considered:
- Genetic Perfection:
"When God created Adam and Eve, there were no mistakes in their DNA... you can make the same argument about the animals." – Dr. Hebert [03:37]
- Environmental Factors:
"If it was environmental, the animals were living pretty much in that same environment." – Dr. Hebert [03:56]
2. Fossil Evidence: Growth Rates and Lifespan Clues
- Growth Rates—Key Clue: Slow maturation in animals is tightly linked to longer lifespans.
"Animals that take longer to mature just tend to live longer." – Dr. Hebert [06:04]
- Birds Today vs. Fossil Birds: Modern birds mostly mature in less than a year, whereas fossils suggest much longer maturation periods.
"Fossil birds generally took a lot longer to mature than today's birds." – Dr. Hebert [07:20]
- Example: Archaeopteryx possibly took up to 2.7 years to mature. [08:05]
- Measuring Fossil Growth:
Fossilized long bones (e.g., femurs, tibias) have growth rings akin to trees."Within the cortex, there are growth rings or bands, and you can count those very similar to the way that you can count growth rings in a tree." – Dr. Hebert [08:51]
Complications:
- Missing Bands: As animals grow, the medullary cavity expands, erasing inner rings, making precise age estimates difficult. [09:53]
3. Size, Maturation, and Extinct Giants
-
Fossil Bird Sizes: Many prehistoric birds were much larger and sometimes had teeth.
“There are fossil birds that were very large... but I think the evidence for longevity is probably stronger on the delayed maturation.” – Dr. Hebert [10:56]
- Many fossil specimens are juveniles, making size and age estimations harder. [11:36]
-
Teeth and Incubation: Some research suggests the lack of teeth in modern birds could result from shorter incubation times (less time for teeth to form).
"There might not be time for the teeth to develop and there might even be epigenetic switches that tell the developing embryo, don't even bother trying to make teeth." – Dr. Hebert [12:56]
Dr. Hebert notes that even evolutionary sources are now considering the incubation-time hypothesis.
4. Dinosaur Lifespans: New Studies Rewrite the Timeline
- Previous Estimates: Early papers claimed huge dinosaurs matured in 15–25 years, which conflicted with expectations for large animal biology.
“That just seems a little bit off... larger animals tend to live longer.” – Dr. Hebert [17:28]
- Innovative New Study (2026):
Recent PeerJ research indicates that Tyrannosaurus rex may have taken up to 40 years to reach full size, aligning better with large animal life histories.- Method: Combining fragmented data sets and treating the number of erased rings as a model parameter allowed more complete growth reconstructions. [19:50–22:40]
"It's the most rigorous study that anybody's ever done. Like I said, I wouldn't be surprised if it becomes standard practice." – Dr. Hebert [22:37]
- Longevity Possibilities: Large dinosaurs, sharks (e.g., Megalodon), and some modern sharks may have lived for centuries—even a millennium. [24:29]
5. Interpretations & Worldview Differences
- Mainstream Science: Evolutionary biologists attribute these patterns to coincidence, mutations, and natural selection, not connecting slow maturation to longevity as creationists do. [25:53]
- Creationist Perspective: Longer pre-flood lifespans for both humans and animals best fit a model with a pristine genome and optimal environment—consistent with Genesis.
“This is something God has programmed into these animals to respond to changing environmental conditions. This is not broken genes. This is something else.” – Dr. Hebert [26:41]
6. Biblical Authenticity & Scientific Confirmation
-
Literal Ages in Genesis: The pattern that patriarchs had children at much older ages fits the fossil data showing slow maturation; such narrative details support authenticity, not symbolism.
“If somebody were making up those ages, I don't think that's the kind of detail that a forager would think to include...” – Dr. Hebert [30:19]
-
Relevance for Christians: Contemporary data supports taking Genesis at face value.
“When we look at the science, when it's done right, we see that it confirms what the Bible says.” – Dr. Hebert [32:13]
-
Call to Christians and Skeptics:
“Those who are scoffers need to seriously reconsider their worldview.” – Dr. Hebert [32:44]
Notable Quotes & Memorable Moments
-
Creation Worldview in a Nutshell
“It grieves me that so many evangelicals seem to be running away from a literal understanding of Genesis when the evidence for it is getting stronger and stronger all the time.” – Dr. Hebert [31:27]
-
On New Research
“We’re not finished on this longevity research. There are four more papers that are already in the pipeline…” – Dr. Hebert [25:22]
-
Science Catching Up to the Bible
“The big one is, to me, that's the takeaway: when we look at the science, when it's done right, we see that it confirms what the Bible says.” – Dr. Hebert [32:13]

Three Key Takeaways
- Scientific Evidence is Increasingly Consistent with a Literal Reading of Genesis: Maturation rates and longevity in fossil animals match the Biblical description of early long-lived humans and fit a creationist paradigm.
- Innovative Research Methods are Transforming Paleontology: New, less subjective approaches to analyzing fossil growth bring deeper insights and challenge earlier evolutionary assumptions about rapid dinosaur maturation.
- Bible-believing Christians Should Be Encouraged: The narrative and details in Genesis align with what is found in the fossil record, strengthening the case for biblical authenticity against both secular and skeptical interpretations.
Listener Q&A Highlight
Q: How did Antarctica accumulate glaciers so rapidly post-flood?
A (Dr. Hebert):
Glaciers could have formed within hundreds (not thousands or tens of thousands) of years due to warmer post-flood oceans, which produced high atmospheric moisture and rapid snow accumulation during the Ice Age. [35:15–36:59]
Conclusion
Episode 117 of The Creation Podcast provides a detailed, engaging discussion on the longevity of pre-flood creatures, showing how new scientific findings are presented as confirming a literal understanding of biblical history. Dr. Hebert’s insights, research citations, and clear explanations make a compelling case for those interested in both faith and science. This episode will be especially valuable to listeners seeking to understand how fossil evidence is interpreted within a young-earth creationist worldview.
