How Old Is the Earth? And How Should Christians Read Genesis 1?
For some Christians, the answer feels obvious: Genesis says God created in six days, so the earth must be young. For others, the scientific evidence for an ancient universe seems overwhelming, and they read Genesis 1 as theological literature rather than a strict timeline. Still others land somewhere in between.
This is one of those topics where Christians need both conviction and humility. The disagreement is not usually over whether Scripture is true. It is over how Scripture should be interpreted, what kind of text Genesis 1 is, and how biblical interpretation should relate to scientific evidence.
That is why this should be treated as an in-house Christian discussion. Across the major views, Christians affirm that God created all things, that creation is good, that human beings bear the image of God, and that the universe is not a cosmic accident. Historic Christianity confesses God as Creator of heaven and earth, even while Christians differ over the age of the earth and the literary shape of Genesis 1.
The real disagreement is narrower: does Genesis 1 intend to give us a chronological account of creation in six ordinary days, or is it doing something more literary, symbolic, and theological while still teaching true things about God, creation, and humanity?
Several major readings are common. Young-earth creationism understands the “days” of Genesis 1 as six normal, consecutive days and usually dates the earth to thousands rather than billions of years old. Old-earth creationism accepts mainstream scientific dating and often reads the “days” as long ages, analogical days, or another non-literal structure. The framework view sees Genesis 1 as carefully arranged theology: days 1–3 form realms, and days 4–6 fill them. Evolutionary creation holds that God created through natural processes, including evolution, while remaining the Author, Sustainer, and Lord of life.
The Hebrew text itself leaves some room for discussion. The word translated “day” — yom — can refer to a normal day, daylight, or a broader period depending on context. Genesis 2:4 even uses “day” in a summary sense: “in the day that the Lord God made the earth and the heavens.” That does not automatically prove an old earth reading. Context still matters. But it does explain why some serious Christians do not think Genesis 1 must be read as six 24-hour days. Christians disagree over whether the structure of Genesis 1 requires ordinary days, permits long ages, or functions primarily as a theological literary framework.
This debate is not new either. Long before modern geology or Darwin, Christians were already asking how Genesis should be read. Augustine, for example, did not simply treat the six days as ordinary days in the modern young-earth sense. He believed creation was from God, purposeful, and ordered, but he also warned Christians not to speak carelessly about the natural world in ways that would make the faith look foolish to outsiders.
That does not mean Augustine was an old-earth creationist in the modern sense. He was not answering our exact questions. But his example reminds us that the early Church was not always as simplistic on Genesis as modern internet debates make it seem. Christians have always had to ask what the text is actually doing.
The churches do not line up neatly on this issue. Some conservative Protestants strongly defend young-earth creationism and see it as the most faithful reading of the text. Many Catholics and Orthodox Christians allow a range of interpretations, provided God is confessed as Creator and the doctrines of humanity, sin, death, and redemption are handled faithfully. Many evangelicals are divided, with serious scholars and pastors on more than one side.
The most important thing is to keep the center clear. Genesis 1 teaches that God is the Creator, the world is His creation, human beings are made in His image, and creation is ordered, good, and purposeful. Whatever view a Christian takes on the age of the earth, those truths cannot be surrendered.
At the same time, Christians should avoid making their interpretation of Genesis 1 the test of whether someone “really believes the Bible.” There are careless versions of every view. There are also thoughtful, reverent versions of every view. A young-earth creationist can love Scripture deeply. So can an old-earth creationist. So can someone who holds the framework view. So can someone who believes God used evolutionary processes while still confessing Him as Creator.
The better question is not only, “Which view is correct?” but also, “Am I representing the other views fairly?” A Christian can hold a strong position without pretending every other view is dishonest, liberal, or unbiblical.
Genesis begins the Bible by telling us who made the world, why creation is good, what human beings are, and where everything ultimately comes from. Those claims are not minor. They are foundational. The debate over days and dates is real, but it should never distract us from the larger confession: “In the beginning, God created the heavens and the earth.”
