The Bible says God made heaven and earth in six days — how does that square with science's "13.8 billion years for the universe, 4.6 billion for the earth"? This article walks you slowly through Genesis 1: verse 1:1 is a panoramic declaration standing at the summit of time; by 1:2 the camera has already zoomed in to the surface of the earth; and the "six days" look more like the step-by-step preparation of a chaotic world into a home for humanity. Explore the elegant parallel structure of the first three days and the last three, the hidden significance of day four, and whether "one day" means 24 hours or an era — and you may find that the language of Scripture and the language of science are two different kinds of discourse that need not be in conflict.
Speaker: Pastor Yunfei Lu · Scripture: 创1:1
Perhaps you have already come to accept that there is a Creator behind the universe — that this is the most reasonable explanation in light of all the evidence. But when you open Genesis chapter 1, you may find yourself stuck on another question:
The Bible says God finished making heaven and earth in six days — how can that possibly line up with science's claim that the universe is 13.8 billion years old and the earth 4.6 billion?
This is a completely reasonable question. Let us read through Genesis 1 together slowly. You will find that the Bible's account of how the universe and the earth came to be has far more depth and texture than many people imagine.
"In the beginning, God created the heavens and the earth." (Genesis 1:1)
This is the most famous sentence in the entire Bible, yet many people read it too quickly and miss an important detail. In the original Hebrew, "heavens" (שָׁמַיִם, shamayim) is plural — literally "the heavens" — referring not merely to the atmosphere above our heads but to the entire vast cosmos: every galaxy, every star, all energy and matter. "Earth" (אֶרֶץ, erets), as the context makes clear, refers to the planet earth.
So what Genesis 1:1 is truly saying is: In the beginning, God created the entire universe and the earth.
Notice: this verse does not belong to "Day One." It is a sweeping summary declaration, standing before the "seven days" that follow. This carries an important implication: if 1:1 is read as an overarching summary, then the "six days" that follow need not be retelling the entire process by which the whole universe came into being from nothing — they may instead be unfolding the story of how the earth was made ready as a place fit for life.
"The earth was formless and empty. Darkness was on the surface of the deep. God's Spirit was hovering over the surface of the waters." (Genesis 1:2)
Notice that the subject of this verse is "the earth," not "the universe." The narrative camera, from this point on, has already pulled in from the vast cosmos to the surface of one particular planet — the earth.
So what does "darkness was on the surface of the deep" mean — is the entire universe dark? No. Countless stars are burning throughout the cosmos at this very moment; light has never been absent from the universe. The subject of the verse tells us: the darkness belongs to "the earth."
A compelling reading is this: viewed from the earth's surface, the early earth was blanketed by thick cloud cover, water vapor, and churning primordial waters — light had not yet broken through into this would-be habitable world. Think of an overcast day when the ground is completely dim, yet if you flew above the clouds in an airplane, the sunlight would be right there. The "darkness on the surface of the deep" in 1:2 does not mean the universe had no light; it means that from the earth's surface, everything was still dark, unformed, and unprepared.
With those two verses in view, the whole arc of the "six days" comes into clear focus. A well-supported reading is this: beginning at verse 3, the "six days" are not primarily about how God brought the entire universe into existence from nothing — they are about how He took a world that was formless and empty and step by step prepared it into a beautiful home fit for human life. It is a narrative told from the earth's surface.
Take Day One as an example:
"God said, 'Let there be light,' and there was light." (Genesis 1:3)
On the earth's-surface reading, this is not saying that light appeared in the universe for the very first time. It is saying that light broke through to the earth's surface for the first time, and darkness and light began to be separated. "There was evening and there was morning" also confirms that the text is already describing the formation of creation's order in the rhythm of earthly time. (Wasn't the sun only created on Day Four? Keep reading.)
This is one of the most beautifully crafted and most often overlooked features of Genesis 1.
Go back to the two paired words in 1:2: "formless and empty." In the Hebrew original the order is actually "formless, empty" (תֹהוּ וָבֹהוּ, tohu va-bohu). The sequence matters, because the "six days" that follow address these two problems in direct correspondence:
| The Two Problems in 1:2 | How God Resolves Them in the Six Days |
|---|---|
| Formlessness (lack of order) | Days 1–3: establishing order by "separating" — light from darkness, waters above from waters below, sea from land |
| Emptiness (lack of content) | Days 4–6: filling the emptiness — sun, moon and stars; birds and sea creatures; land animals and humanity |
Even more elegant: the first three days build the "stage" (the boundaries), and the last three days bring in the "actors" (the inhabitants), with a precise one-to-one correspondence:
| Pairing | Days 1–3 (Building the Stage · Establishing Boundaries) | Days 4–6 (Bringing in the Actors · Filling the Boundaries) |
|---|---|---|
| 1 ↔ 4 | Day 1: separating light and darkness (boundaries of time) | Day 4: sun, moon, and stars (governing day and night) |
| 2 ↔ 5 | Day 2: separating waters above and below, forming the expanse (boundaries of space) | Day 5: birds fill the sky, sea creatures fill the waters |
| 3 ↔ 6 | Day 3: separating sea and land, bringing forth plants (a dwelling for life) | Day 6: land animals and humanity (inhabitants of the dwelling) |
However you understand the length of each "day," this literary structure makes one thing unmistakable: God is not working in chaos and disorder. He works like a master architect — first laying the foundation, then building the walls, then furnishing the interior; first establishing boundaries, then giving those boundaries their inhabitants.
Many readers are puzzled: if the sun was only created on Day Four, where did the light come from on Days One through Three? How was there "evening and morning"?
A closer look at the Hebrew original reveals a clue worth noting. The verb used in 1:1 is "created" (בָּרָא, bara), a word with strong connotations of divine origination in the Old Testament, whose subject is almost always God. But the verb used in 1:16 for Day Four is "made" (עָשָׂה, asah), a broader word that can mean to make, arrange, appoint, or accomplish.
This distinction opens up a possible reading: "making the sun, moon, and stars" on Day Four need not mean they came into existence from nothing at that moment. It may mean that God appointed them to their role as markers of time. In other words, the sun, moon, and stars already belonged to "the heavens" created in 1:1 "in the beginning"; what Day Four emphasizes is that they became visible from the earth's surface and were appointed by God as "signs to mark seasons and days and years" (1:14).
This provides a compelling answer to the apparent contradiction: light already existed during the first three days — those days emphasize light breaking through to the earth's surface and beginning to distinguish day from night. The sun, moon, and stars belong to the creation of 1:1; Day Four emphasizes their appearing and their appointment as markers of time.
This is a question on which Christians have held different views throughout church history. Two main readings have emerged:
Young Earth Creationism holds that "one day = 24 hours," meaning the universe and the earth are both young (around six thousand years old). This position takes the text at face value but requires rejecting the mainstream scientific consensus on the age of the universe and the earth.
Old Earth Creationism observes that the Hebrew word for "day" (יוֹם, yom) can itself refer to a longer period of time. For example, Genesis 2:4 speaks of "the day that the LORD God made the earth and the heavens" — clearly not a 24-hour period. On this reading, each "day" may represent a geological era, and this does not conflict with the scientific estimates of 13.8 billion years for the universe and 4.6 billion for the earth.
What matters most is this: both positions affirm that God is the Creator of the universe and that Scripture is God's word. Their disagreement is not over "whether God created it" but over "what the time details mean." This is a difference on which Christians can hold one another with grace and charity; it need not become a source of division.
The language of Scripture and the language of science are two different kinds of discourse — but they are not necessarily in conflict.
The Bible's purpose is not to give us a textbook of physics or geology. It is to tell us something far more important:
These are questions science itself does not undertake to answer. Science tells us how the world works; Scripture tells us why the world exists and what we are here for. The two can be distinguished without being set against each other. As a well-known analogy puts it: science can tell you that the chemical composition of water is H₂O; Scripture tells you that someone poured that glass of water for you.
