"Science has disproved God." You have probably heard this — maybe from a friend, a family member, or a podcast. It is one of the most confident claims in modern atheism. It is also one of the least examined.

Here is the honest answer: science has not disproved God. It cannot. And understanding why is important for any Christian who wants to engage this conversation well.

Science is a method for investigating the natural world. It uses observation, experimentation, and repeatable testing to build knowledge about how physical processes work. It is extraordinarily good at what it does.

But science, by its own design, only investigates natural causes. It cannot, in principle, detect or rule out a supernatural cause. Asking science to disprove God is like asking a metal detector to find plastic. The tool is not designed for the job.

This is not a retreat. It is a clarification. The question of whether God exists is a philosophical and theological question, not a scientific one. Science can inform that conversation — but it cannot settle it.

Here is what is interesting: when you look at what science has actually discovered about the universe, the picture is not hostile to theism. In several ways, it is surprisingly friendly to it.

The origin of the universe. Modern cosmology tells us the universe had a beginning — the Big Bang. Before that moment, there was no matter, no energy, no space, no time. Something brought the universe into existence from nothing. That is not a scientific explanation — it is a philosophical one. And "a personal God created the universe" is a serious candidate.

Fine-tuning. The physical constants of the universe — the strength of gravity, the mass of the electron, the cosmological constant — are calibrated with extraordinary precision for the existence of life. Adjust any of them slightly, and the universe collapses, or never forms stars, or never produces chemistry. The fine-tuning of the universe is one of the most discussed topics in contemporary philosophy of science. It does not prove God, but it is exactly what you would expect if a personal God designed the universe for life.

Consciousness. Science can describe the neural correlates of consciousness — which parts of the brain are active when we think or feel. But it cannot explain why there is subjective experience at all. Why is there something it is like to be you? This is what philosophers call the "hard problem of consciousness," and it remains genuinely unsolved. A materialist universe has no obvious place for it. A universe created by a personal God does.

The "science vs. religion" narrative implies that informed, rational people choose science and leave God behind. But this is simply not true.

Francis Collins, who led the Human Genome Project, is a committed Christian. John Polkinghorne was a Cambridge physicist before becoming an Anglican priest. Alvin Plantinga, one of the most respected philosophers of the 20th century, has argued rigorously for the rationality of theistic belief. The list is long.

These are not people who have not thought carefully. They are people who have thought carefully and concluded that faith and science are not enemies.

The real question is not "science or God?" The real question is: what is the best explanation for everything that exists — the universe, its fine-tuning, the emergence of life, the existence of consciousness, the reality of moral obligation, the historical evidence for the resurrection of Jesus?

Science is part of that conversation. But it is not the whole conversation. And Christians should not be intimidated into thinking that the scientific method has ruled out the God of the Bible. It has not. It cannot.

When someone says "science has disproved God," ask them what they mean. What specific scientific finding rules out God? Usually, the answer is something like evolution or the Big Bang — neither of which, on examination, actually rules out a creator.

Be curious, not defensive. The evidence is on your side more than the culture suggests.

Science describes how the universe works. It does not explain why there is a universe to describe.
