Contemporary secular science estimates the universe to be around 13.8 billion years old, emerging from what is termed the Big Bang—a moment of rapid expansion in spacetime that included all matter, energy, and physical laws, compressed initially into a singularity of nearly infinite gravitational intensity. In contrast, the Holy Scriptures present an account in which God created the universe in six days, approximately 6,000 years ago, as deduced from biblical chronology and its relationship to established historical events. For many centuries, the Judeo-Christian cultural sphere (and others influenced by it) largely accepted this biblical timeline. However, with advancements in scientific understanding, this traditional view has been increasingly questioned, and the modern scientific model is often seen as providing a more accurate explanation of the universe’s origins than the seemingly outdated perspective of the Bible. But could science, despite its advancements, still be mistaken? Could it be that the universe is actually only 6,000 years old, rather than billions?
Firstly, it is crucial to observe that the Big Bang theory, along with theories of biological evolution and an old Earth, is based on a number of assumptions that may be considered unsubstantiated. The two most notable of these assumptions are naturalism and uniformitarianism.1 Naturalism, along with materialism, asserts that everything that exists is part of the natural world. This view accepts only natural processes, denying the existence of supernatural beings or events that could interfere with natural laws. From this foundation, uniformitarianism arises as a logical extension.
Historical science, by its philosophical framework, excludes any realities beyond the physical nature of the universe, grounding its conclusions solely in natural data. Consequently, this approach may result in—and indeed does yield—an incomplete view of the reality we inhabit.
In Earth sciences, the concept of geological uniformitarianism suggests that current natural geological and radioactive processes provide insights into past geological events. This idea is often summarised in the phrase, ‘the present is the key to the past’. Although this principle primarily applies to Earth’s geology, it also appears to influence the scientific approach to understanding the origin and destiny of the universe. Current estimates of the universe’s age rely on the Hubble constant, derived from observing the velocities at which galaxies move away from the Milky Way, reflecting the universe’s expansion. This expansion implies that the universe must have been smaller in the past, at one time condensed into a single point. Today, this moment is calculated to have occurred 13.7 billion years ago.2
Secular science, grounded in naturalism and uniformitarianism, promotes this perspective. However, as Dr. J. Lisle observes, both naturalism and geological uniformitarianism are ultimately philosophical assumptions.3 These philosophical assumptions shape our understanding of present reality, as explored through operational science, and extend to our interpretations of both the past, within historical science, and the future. Historical science, due to its philosophical foundations, confines its scope to the physical universe, relying solely on natural evidence. As a result, this approach may offer a limited perspective on the full scope of reality.
As Christians, can we trust historical sciences that dismiss the possibility of large-scale supernatural interventions by God? Many Christians do—holding faith in the biblical God while also accepting evolutionary theory and the Big Bang theory, posited at 13.8 billion years. This approach forms the basis of theistic evolution and progressive creationism (old-Earth creationism), which appear to align with scientific evidence.
One of the main challenges young-Earth creationists face, especially in discussions with evolutionists and progressive creationists, is the question of how light from distant stars reaches us.4 Why is this an issue? Current science tells us that light travels at nearly 300,000 kilometers per second, covering about 9.5 trillion kilometers in a year—a distance known as a light-year. Proxima Centauri, the closest star to our Sun, is 4.24 light-years away, or around 40 trillion kilometers. Yet, many stars in our own galaxy are far more distant, lying well beyond 6,000 light-years. Galaxies beyond the Milky Way are millions, even billions, of light-years away. Calculations suggest that the most distant galaxies we can see are around 46.1 billion light-years from Earth, marking the edge of the observable universe.5
The Speed of Light in Space
Do these findings challenge the young-Earth creationist belief that the universe is only 6,000 years old? Many creationists have responded to this issue with a variety of arguments, though some of these may be seen as unpersuasive.6 One argument proposes that the distances between stars and galaxies are not as vast as commonly understood; however, observational evidence overwhelmingly confirms these immense distances. Another idea suggests that God created light ‘in transit,’ as if it were already on its way from stars and galaxies that had not yet been formed. But would this imply a form of divine deception? For example, could Adam have looked up and seen stars thousands of light-years away that, in reality, did not yet exist? From a biblical perspective, this seems improbable, given the assertion that God cannot lie (Titus 1:2).
However, some creation scientists propose alternative solutions to this dilemma, suggesting that God may have adjusted the speed of light or employed relativistic physics involving time variability. Research on this topic is ongoing, though it faces some internal critique.7 Until conclusive answers emerge, Christians should remember that God is omnipotent and the Creator of all that exists, including physical laws such as gravity and electromagnetism. As an all-powerful being, He could conceivably “adjust” these laws to accomplish His purposes in creating the universe.8
Incidentally, the speed of light poses a significant challenge for advocates of evolutionary cosmology and the Big Bang theory, commonly referred to as the ‘horizon problem’.9 According to this theory, the rapid expansion of the universe would have prevented energy (travelling at the speed of light) from moving between distant regions—such as a warmer area (e.g., point A) and a cooler one (e.g., point B)—in the early universe. This energy transfer would be necessary to equalise temperatures across the cosmos. However, observations of the cosmic microwave background (CMB) radiation reveal a remarkably uniform temperature throughout the universe, suggesting that such an energy exchange did, in fact, occur—though the mechanism behind this remains unknown.
To address this issue, scientists proposed the theory of cosmic inflation, suggesting that an exchange of energy occurred before the universe’s rapid expansion phase. According to this theory, inflation—an extremely rapid expansion of the universe—occurred, then slowed down significantly. However, scientists remain uncertain about what might have triggered this initial inflation or why it abruptly decelerated; thus, the theory currently lacks direct scientific evidence. Consequently, the speed of light cannot be used as definitive evidence against a young universe, as it remains a double-edged sword in this debate.10
In conclusion, could God have created our vast and mature universe only 6,000 years ago, within the span of a few days? This remains a possibility, as the Bible affirms that nothing is impossible for an all-powerful God (Jeremiah 32:17). The Book of Genesis presents this account, and it would be unwise for a Christian to abandon its description of God’s supernatural and relatively recent creation of the universe in favour of purely naturalistic explanations that overlook God’s divine actions.
