The age of the Earth is a topic that sparks considerable debate, not just in scientific circles, but also within religious discussions. From online forums to classrooms and even within churches and Christian institutions, the question “how old is the earth?” is frequently raised. The core of the discussion often boils down to two fundamentally different perspectives, separated by billions of years.
One viewpoint, rooted in modern science, posits an Earth that is billions of years old. The other perspective, drawing primarily from a literal interpretation of the Bible, suggests a much younger Earth, thousands of years in age. This vast difference necessitates a deeper look into the origins of these calculations and the worldviews that underpin them, especially when we ask, “How Old Is The Earth According To The Bible?”
The Genesis of the Young-Earth Perspective
The concept of a young Earth, thousands of years old, isn’t derived from explicit statements in the Bible declaring “the earth is 6,000 years old.” Instead, it emerges from a careful reading and interpretation of biblical texts, particularly the book of Genesis. Rather than giving a direct age, the Bible provides what can be considered a “birth certificate” of sorts, offering the information needed to calculate the Earth’s age since its creation.
Genesis 1 clearly states the Earth was formed on the first day of creation (Genesis 1:1–5). This starting point allows for a timeline to be constructed. By following the genealogical records from Adam to Abraham in Genesis 5 and 11, and then adding the period from Abraham to the present day, an estimate for the Earth’s age can be derived.
Let’s perform a simplified calculation to illustrate this. The timeline begins with the five days of creation that preceded Adam’s arrival on day six. Adding the genealogies from Adam to Abraham, based on the Masoretic Hebrew text, yields approximately 2,000 years. Historical consensus, even among secular scholars, places Abraham’s life around 2,000 B.C., which is roughly 4,000 years ago from our present time.
This gives us a basic calculation:
5 days + ~2,000 years (Adam to Abraham) + ~4,000 years (Abraham to present) = ~6,000 years
In this calculation, the initial five days become negligible when considering millennia. Numerous scholars, meticulously examining the Masoretic text and biblical details, have independently arrived at a similar timeframe of approximately 6,000 years for the Earth’s age, dating back to around 4000 B.C. Notable figures who have undertaken this chronological work include Dr. Floyd Jones in his recent scholarship and Archbishop James Ussher, whose work dates back centuries.
Table 1. Key Chronologists and Their Young-Earth Calculations
| Name | Age Calculated | Reference and Date |
|---|---|---|
| Archbishop James Ussher | 4004 B.C. | The Annals of the World, A.D. 1658 |
| Dr. Floyd Nolan Jones | 4004 B.C. | The Chronology of the Old Testament, A.D. 1993 |
It’s a common misconception that Ussher and Jones were outliers in reaching a 4004 B.C. creation date. However, Dr. Jones’s research reveals a broader range of chronologists who, using biblical texts, calculated Earth’s creation dates ranging from 5501 to 3836 B.C. A selection of these calculations is presented in Table 2.

| 31 | M. Beroaldus | c. 1575 | 3927 |
| 32 | A. Helwigius | c. 1630 | 3836 |
The variations in these dates arise from several factors. Two significant reasons for these discrepancies are:
-
Textual Variations: Some chronologists utilized the Septuagint, a Greek translation of the Hebrew Old Testament from around 250 B.C., or other early translations, instead of the Masoretic Hebrew text. The Septuagint, while generally reliable, contains some inaccuracies, notably in the Genesis genealogies. For example, the Septuagint’s chronology suggests Methuselah lived beyond the Flood without being on the Ark, a clear inconsistency.
-
Interpretational Challenges: Certain points in the biblical timeline are not explicitly detailed and require careful interpretation across multiple passages. These include the duration of the Israelites’ sojourn in Egypt and Terah’s age at Abraham’s birth. These ambiguities lead to differing calculations among chronologists, as explored in detail by Jones and Ussher.
The first four chronologists in Table 2 (Julius Africanus, George Syncellus, John Jackson, and Dr. William Hales) based their calculations on the Septuagint. This version often presents significantly longer lifespans for the patriarchs before the birth of their first sons compared to the Masoretic text and the Samaritan Pentateuch. This difference in patriarchal ages in the Septuagint contributes to a longer overall timeline. Table 3 highlights these textual variations.
Table 3. Patriarchal Ages at the Birth of the Next Son: Septuagint vs. Masoretic vs. Samarian Texts
| Name | Masoretic | Samarian Pentateuch | Septuagint |
|---|---|---|---|
| Adam | 130 | 130 | 230 |
| Seth | 105 | 105 | 205 |
| Enosh | 90 | 90 | 190 |
| Cainan | 70 | 70 | 170 |
| Mahalaleel | 65 | 65 | 165 |
| Jared | 162 | 62 | 162 |
| Enoch | 65 | 65 | 165 |
| Methuselah | 187 | 67 | 167 |
| Lamech | 182 | 53 | 188 |
| Noah | 500 | 500 | 500 |
Excluding the Septuagint-based calculations from Table 2 and including the calculations of Jones and Ussher, the average creation date is approximately 4045 B.C. This average still points to an Earth around 6,000 years old.
Cross-Cultural Historical Timelines
Beyond the biblical text, historical records from cultures worldwide offer intriguing perspectives on the age of the Earth. From a biblical standpoint, we might expect these independent historical accounts to align more closely with the biblical timeframe of thousands of years rather than billions. This expectation is based on the understanding that humanity descended from Noah and dispersed from Babel, carrying memories of early history. We might also anticipate some variations across cultures as oral traditions and uninspired records were transmitted and interpreted differently in various regions.
God
Young’s Analytical Concordance of the Bible compiles dates for Earth’s creation from diverse cultures, as researched by William Hales, citing various historical authorities. Table 4 presents a selection of these dates.
Historian Bill Cooper’s research in After the Flood further highlights ancient chronologies. Anglo-Saxon records, such as the Laud and Parker Chronicles, suggest a 5,200-year span from creation to Christ. Nennius’s history of ancient Britain indicates 5,228 years from creation to Christ. Remarkably, Irish chronology aligns closely with Ussher and Jones, placing creation around 4000 B.C. Even Mayan records include a date for a significant flood event around 3113 B.C.
These historical timelines, meticulously compiled by historians, offer compelling support for a young-earth timeframe of thousands of years, contrasting sharply with billions of years.

The Emergence of the Old-Earth View
The prevailing view before the 1700s leaned towards a young Earth, approximately 6,000 years old. Challenges to this biblical chronology began to surface in the late 18th century, largely driven by a shift away from a God-centered worldview in scientific inquiry. Early proponents of an old Earth included Comte de Buffon, who suggested an age of at least 75,000 years; Pièrre LaPlace, who envisioned a vast, indefinite timescale; and Jean Lamarck, also proposing long ages for Earth’s history.
However, the concept of millions of years gained significant traction within geology during the 19th century. Figures like Abraham Werner, James Hutton, William Smith, Georges Cuvier, and Charles Lyell began interpreting geological formations as evidence for immense timescales, prioritizing geological interpretations over biblical accounts. Werner estimated Earth’s age at around a million years. Smith and Cuvier believed vast ages were needed to form rock layers. Hutton argued for an Earth with no discernible beginning based on geological evidence, and Lyell, building upon Hutton’s ideas, advocated for “millions of years.”
These geologists promoted the idea that geological layers formed gradually over extended periods, mirroring processes observed today. Hutton articulated this principle:
The past history of our globe must be explained by what can be seen to be happening now. . . . No powers are to be employed that are not natural to the globe, no action to be admitted except those of which we know the principle.
This philosophy became known as naturalistic uniformitarianism, emphasizing gradual processes and excluding catastrophic events like Noah’s Flood. While some, like Cuvier and Smith, acknowledged multiple catastrophes separated by long intervals, uniformitarianism became the dominant paradigm in geology.
From a biblical perspective, the global flood described in Genesis 6–8 directly contradicts the concept of millions of years. A global flood would reshape the Earth’s surface, depositing vast fossil layers rapidly. This cataclysmic event could explain geological formations attributed to millions of years, potentially erasing evidence for slow, gradual processes. However, by the mid-19th century, even much of the Church began to accept the old-earth framework of secular geology, often downplaying or rejecting the global flood and the biblical age of the Earth.
Later, in 1899, Lord Kelvin (William Thomson), using calculations based on Earth’s cooling rate as a molten sphere, estimated a maximum age of 20–40 million years (revised down from an earlier estimate of 100 million years in 1862). The advent of radiometric dating in the early 20th century dramatically expanded age estimates. Arthur Holmes, in his 1913 book The Age of the Earth, proposed 1.6 billion years. Current estimates, based on radiometric dating, place Earth’s age at approximately 4.5 billion years, with the universe estimated at around 14 billion years.
Table 5. Key Proponents of Old-Earth Timelines
| Who? | Age of the Earth | When Was This? |
|---|---|---|
| Comte de Buffon | 78 thousand years old | 1779 |
| Abraham Werner | 1 million years | 1786 |
| James Hutton | Perhaps eternal ages | 1795 |
| Pièrre LaPlace | Long ages | 1796 |
| Jean Lamarck | Long ages | 1809 |
| William Smith | Long ages | 1835 |
| Georges Cuvier | Long ages | 1812 |
| Charles Lyell | Millions of years | 1830–1833 |
| Lord Kelvin | 20–100 million years | 1862–1899 |
| Arthur Holmes | 1.6 billion years | 1913 |
| Clair Patterson | 4.5 billion years | 1956 |
However, growing scientific evidence challenges the reliability of radiometric dating methods. This evidence reinforces the biblical timeline as a more accurate account of creation history for those who trust in the Bible’s narrative.
While modern secular geologists now acknowledge some catastrophic events in Earth’s history, uniformitarian thinking remains influential, and the global, catastrophic flood of Noah’s time is largely dismissed.
Ultimately, the age of the Earth debate hinges on a fundamental question of trust: Do we prioritize humanity’s fallible and evolving interpretations of the past, or do we trust God’s perfect eyewitness account of creation, the global flood, and the age of the Earth as revealed in the Bible?
Challenges to Uniformitarian Dating Methods
Radiometric dating has become central to the billion-year age of the Earth. However, it’s crucial to understand that radiometric dating, like all uniformitarian dating methods, relies on assumptions when extrapolating present-day processes into the distant past. These assumptions, inherent in radiometric dating, can be framed as critical questions:
- Initial amounts: What were the initial concentrations of parent and daughter isotopes in the rock sample?
- System closure: Has the system remained closed, preventing the addition or removal of parent or daughter isotopes over time?
- Decay rate constancy: Has the radioactive decay rate remained constant throughout history?
If these assumptions were consistently accurate, radiometric dates should align with each other and with dates from other uniformitarian methods. However, radiometric dates often disagree internally and with dates derived from other uniformitarian dating methods used to estimate Earth’s age. Examples of these alternative methods include measuring salt influx into the oceans, the decay rate of Earth’s magnetic field, and human population growth rates.
The late Dr. Henry Morris compiled a list of 68 uniformitarian age estimates for the Earth from both Christian and secular sources. Table 6 summarizes his findings, keeping in mind the current accepted age of 4.54 billion years based on radiometric dating of meteorites.
Table 6. Uniformitarian Age Estimates (Excluding Radiometric Dating) Compiled by Morris
| Age Range | 0 – 10,000 years | >10,000 – 100,000 years | >100,000 – 1 million years | >1 million – 500 million years | >500 million – 4 billion years | >4 billion – 5 billion years |
|---|---|---|---|---|---|---|
| Number of methods* | 23 | 10 | 11 | 23 | 0 | 0 |
Note: Maximum age used for ranges, generous to old-earth views. One uncertain date excluded, total estimates: 67. Some methods related to Saturn, Sun, etc., but included due to Earth being older biblically.
As Table 6 demonstrates, uniformitarian age estimates, excluding radiometric dating, rarely approach billions of years. Most methods yield maximum ages far below 4.5 billion years, with only two reaching up to 500 million years.
Furthermore, inconsistencies within radiometric dating itself cast doubt on its reliability. Carbon-14 (¹⁴C) dating, for instance, has a relatively short half-life of 5,730 years. Theoretically, after approximately 100,000 years, ¹⁴C should be virtually undetectable in organic material. However, ¹⁴C has been consistently found in samples purportedly millions of years old, such as wood within lava flows dated by other radiometric methods to be millions of years old. Coal and diamonds, found in or between rock layers assigned millions of years by geological timescales, have yielded ¹⁴C ages of only tens of thousands of years. These findings challenge the long-age interpretations. If these materials were truly millions of years old, detectable ¹⁴C should be absent.
Potassium-argon (K-Ar) dating, often considered a more reliable method, also exhibits significant discrepancies. Geologist Dr. Andrew Snelling highlights several instances where K-Ar dating yields erroneous results on rocks of known age (Table 7).
Table 7. Potassium-Argon (K-Ar) Dating Errors
| Volcanic eruption | Rock Formation Date | K-Ar Radiometric Date |
|---|---|---|
| Mt. Etna basalt, Sicily | 122 B.C. | 170,000–330,000 years old |
| Mt. Etna basalt, Sicily | A.D. 1972 | 210,000–490,000 years old |
| Mount St. Helens, WA | A.D. 1986 | Up to 2.8 million years old |
| Hualalai basalt, Hawaii | A.D. 1800–1801 | 1.32–1.76 million years old |
| Mt. Ngauruhoe, New Zealand | A.D. 1954 | Up to 3.5 million years old |
| Kilauea Iki basalt, Hawaii | A.D. 1959 | 1.7–15.3 million years old |
These examples raise a critical question: If radiometric dating methods fail to accurately date rocks of known age, how can they be trusted to provide reliable ages for rocks of unknown age? It becomes more reasonable to place trust in the Word of God, who created the world and provided a historical account in the Bible sufficient for understanding creation history and the age of the Earth.
Conclusion: Trusting the Biblical Timeline
When we begin with the Bible as our foundation, a consistent picture emerges: the Earth is approximately 6,000 years old. Conversely, relying on human dating methods yields a wide and often contradictory range of ages, from thousands to billions of years, with most non-radiometric methods falling far short of billion-year estimates.
Furthermore, historical timelines from diverse cultures provide independent support for a younger Earth, aligning with the biblical timeframe. Radiometric dating, while widely used, has demonstrated significant inaccuracies and inconsistencies.
The debate about the age of the Earth ultimately boils down to a matter of worldview and trust. Will we trust the pronouncements of an all-knowing God, or will we rely on the ever-changing assumptions and interpretations of imperfect humans?
Thus says the Lord: “Heaven is My throne, and earth is My footstool. Where is the house that you will build Me? And where is the place of My rest? For all those things My hand has made, and all those things exist,” says the Lord. “But on this one will I look: On him who is poor and of a contrite spirit, and who trembles at My word” (Isaiah 66:1–2).
