The Age Of The Earth Debate

Young earth | Old earth

Young Earth Proposals and Proponents

If we mean the first person to calculate a specific chronology for the age of the earth or creation based on the Bible, the earliest examples go back to Jewish and early Christian scholars who tried to add up the genealogies in Genesis. Here’s a brief historical timeline:


🕎 Early Jewish Chronologies


✝️ Early Christian Chronologies


Medieval and Early Modern Christian Chronologies


🧭 Summary

Era Scholar Approx. Date of Creation Notes
~160 CE Jose ben Halafta (Seder Olam Rabbah) 3761 BCE Jewish traditional chronology
~180 CE Theophilus of Antioch 5698 years before his time (~5500 BCE) Early Christian estimate
~221 CE Julius Africanus 5500 BCE First full Christian biblical chronology
~735 CE Bede 3952 BCE Anglo-Saxon scholar
1650 CE James Ussher 4004 BCE Most famous “young earth” date

So, the idea of a “young earth” is ancient, but James Ussher (1650) is the person who first popularized a precise and widely adopted date, making him the name most associated with the specific “4004 BCE” figure.

Archbishop James Ussher

Ussher’s method is fascinating because it shows how serious early scholars were about harmonizing all historical and biblical data available to them. Let’s walk through how Archbishop James Ussher (1581–1656) arrived at the famous date of 4004 BCE for the creation of the world.


🧠 1. His Goal

Ussher’s aim was to construct a complete, continuous chronology from the moment of Creation up to the birth of Christ — entirely from Scripture and known historical records.

He published his results in Annales Veteris Testamenti (1650) and later extended them through Annales Novi Testamenti (1654).


📜 2. His Starting Point — The Biblical Genealogies

Ussher began by adding up the “years lived” and “ages at fatherhood” in the Bible — mainly from Genesis 5 and 11. These genealogies list how long each patriarch lived and how old they were when their son was born.

He used the Masoretic Text (the Hebrew Old Testament), not the Greek Septuagint, because he considered it more reliable.
→ This choice matters: the Septuagint’s numbers would make the world roughly 1,500 years older than the Hebrew version.


⏳ 3. The Key Biblical Periods He Added Together

Here’s a simplified breakdown of the timeline segments Ussher used:

Period Years Description
From Creation to the Flood 1656 Genesis 5 genealogy
From the Flood to Abraham 367 Genesis 11 genealogy
From Abraham to Exodus 430 Galatians 3:17 and Exodus 12:40
From Exodus to Solomon’s Temple 479 1 Kings 6:1
From the Temple to Babylonian captivity 430 Based on Kings/Chronicles
From Captivity to Christ 562 Using Persian, Greek, and Roman historical records

Total: 4004 years from Creation to the year he calculated for Christ’s birth.


📅 4. Aligning Biblical Events with Known History

Ussher didn’t rely only on the Bible. He cross-checked his timeline with secular historical sources — e.g.:

For instance:


🌍 5. Why October 23, 4004 BCE?

Once he had the year, Ussher wanted the exact day of Creation.

He reasoned that:

Therefore, he concluded:

The world began at nightfall preceding Sunday, October 23, 4004 BCE.


📖 6. Influence


⚙️ Summary of His Method

Step Basis Tool
1️⃣ Add genealogies Genesis 5 & 11 Masoretic ages
2️⃣ Add intervals (Abraham → Solomon → Exile → Christ) Other OT texts + New Testament Biblical arithmetic
3️⃣ Cross-check Secular chronologies (Babylonian, Persian, Roman) Josephus, Ptolemy, classical historians
4️⃣ Fix to calendar Jewish year start & astronomical equinox Contemporary almanacs
5️⃣ Result Sunday, Oct 23, 4004 BCE Final Ussher date

Here’s a clear timeline chart showing how Archbishop James Ussher arranged world history from Creation (4004 BCE) to the birth of Christ, according to his 1650 chronology.

🧾 Summary



Young Earth

Old Earth Proposals and Proponents

The idea that the Earth might be much older than a literal reading of the Bible’s chronology (often associated with a “young earth” of about 6,000 years) has appeared in several different forms across history. Below is a summary of major “old earth” proposals and their key proponents, arranged roughly in chronological order.


🏛️ 1. Ancient and Medieval Precursors (before 1600)


🌍 2. Early Modern Period (1600s–1700s): Geological Realization

As geology developed, scholars began to recognize evidence of a very ancient Earth.

A. Pre-Geological Theologians

B. Early Geologists (Natural Philosophers)


⛰️ 3. The Birth of Modern Geology (late 1700s–early 1800s)

This period introduced natural explanations for Earth's age and structure.


📖 4. Theological “Old Earth” Interpretations (1800s onward)

Many Christian thinkers sought to reconcile the Bible with geological evidence.

A. Gap Theory (“Ruin-Restoration”)

B. Day-Age Theory

C. Progressive Creationism


🔬 5. Scientific Cosmology and Deep Time (19th–20th centuries)
