You’ve probably heard someone say, “I believe in science, not God” — as if you have to pick one. It sounds bold and modern, but here’s the thing: that statement isn’t actually scientific. It’s philosophical. And understanding the difference changes everything.

Science Has Limits (And That’s Okay)

Science is incredibly powerful. It can tell us about the age of the universe, how DNA replicates, and why planets orbit stars. But science operates within a specific lane: it studies the natural, repeatable, observable world. This approach is called methodological naturalism — the practice of looking for natural explanations for natural phenomena.

That’s totally legitimate. But some people slide from methodological naturalism into metaphysical naturalism — the belief that nature is all there is. That’s not a scientific conclusion; it’s a philosophical assumption. As Oxford mathematician John Lennox puts it: “Nonsense remains nonsense, even when talked by world-famous scientists.” Science can’t prove or disprove God any more than a metal detector can disprove the existence of plastic.

Nobel laureate Richard Feynman acknowledged this boundary: the scientific method is designed to discover how nature behaves, not to answer whether nature is all that exists.

The Scientists Who Didn’t Get the Memo

If science really disproved God, you’d expect the greatest scientists in history to have been atheists. But the record tells a very different story:

• Isaac Newton wrote more about theology than physics and saw his scientific work as uncovering God’s design.
• James Clerk Maxwell, who unified electricity and magnetism, was a devout Presbyterian.
• Georges Lemaître, the physicist who first proposed the Big Bang theory, was a Catholic priest.
• Francis Collins, who led the Human Genome Project, became a Christian after studying the elegance of DNA. He describes the genetic code as “the language of God.”

Collins writes in The Language of God: “The God of the Bible is also the God of the genome. He can be worshipped in the cathedral or in the laboratory.”

These aren’t fringe figures clinging to outdated ideas. They represent the pinnacle of scientific achievement — and they saw no conflict between rigorous science and sincere faith.

Science Actually Points Somewhere

Here’s what’s fascinating: the more we discover about the universe, the harder it becomes to explain it without something beyond nature.

• The Big Bang tells us the universe had a beginning. Everything that begins to exist has a cause — so what caused the universe?
• Fine-tuning of physical constants (the strength of gravity, the cosmological constant, the mass of the proton) is so precise that even tiny variations would make life impossible. Physicist Roger Penrose calculated the odds of our universe’s low-entropy initial conditions at 1 in 10^(10^123).
• The information in DNA — a four-letter digital code that stores, transmits, and executes instructions — looks remarkably like the product of intelligence, not random chemistry.

Alister McGrath, an Oxford biophysicist turned theologian, argues in The Big Question that the intelligibility of the universe — the fact that it can be understood through mathematics — is itself a clue. Why should a universe born from random processes be comprehensible to human minds? The Christian answer is that a rational Creator made a rational universe and gave us rational minds to explore it.

The Real Question

The question isn’t really “science or God?” — it’s “what’s the best explanation for what science reveals?” Science gives us the data. But interpreting that data — asking why the universe exists, why it’s fine-tuned, why it’s intelligible — takes us beyond the laboratory and into philosophy and theology.

As Lennox often says, the more we understand about the universe, the more it points beyond itself. Science doesn’t bury God. If anything, it digs up evidence that demands a deeper explanation.

So next time someone says “science disproves God,” you can gently point out: science is a method, not a worldview. And the method keeps turning up results that are remarkably consistent with a universe that was designed on purpose, by someone with a spectacular imagination.
