Science has found no evidence for God, so belief in God is unscientific

Why this objection feels so strong

Science has an extraordinary track record. Things people once put down to spirits or divine anger, like thunderstorms, plagues and eclipses, turned out to have natural causes. It is easy to extrapolate: if every gap has been filled by a natural explanation so far, perhaps the idea of God is just the last gap waiting to close. That is a fair instinct, and believers should take it seriously rather than retreat to "God did it" whenever science is stuck.

What science can and can't test

Science works by studying regular, measurable patterns in the natural world. That is its strength. But it also marks its limits. The question "Does anything exist beyond nature?" is not a question about a pattern inside nature, so no experiment can settle it either way. Saying "science has found no evidence for God" is a bit like saying a metal detector has found no evidence of plastic. The tool was never built to detect that kind of thing.

The claim "only what science can verify is worth believing" is also not itself a scientific finding. No experiment could confirm it. That philosophy, sometimes called scientism, undercuts itself.

Where the evidence actually points

Most arguments for God don't compete with science; they start from what science discovers. The universe appears to have had a beginning, which raises the question of what caused it (see the Kalam cosmological argument). The laws of physics are mathematically elegant and appear finely tuned for life. And the very fact that the universe is understandable at all is something many early scientists, like Johannes Kepler and Isaac Newton, saw as pointing to a rational Creator. These are philosophical inferences from scientific data, not gaps in it.

Has science disproved God?

Some popular writers, like Richard Dawkins in The God Delusion, argue that God is a scientific hypothesis and a poor one. But many working scientists disagree. Francis Collins, who led the Human Genome Project, is a Christian and wrote The Language of God about how he holds faith and science together. The philosopher Alvin Plantinga argues in Where the Conflict Really Lies that the real conflict is between science and naturalism, the belief that nature is all there is, not between science and faith.

If science had disproved God, we would expect to point to the experiment that did it. There isn't one. What there is, instead, is a philosophical choice to interpret scientific findings within a naturalistic framework.

A fair concession

Skeptics are right that "God of the gaps" reasoning is weak. If belief in God rested on what science hasn't explained yet, every new discovery would shrink it. The stronger case is the opposite: the more we learn about the order, beginning and intelligibility of the universe, the more there is to explain.

The bottom line

Science is a gift, and Christians have every reason to love it. But it answers "how" questions about the natural world. Whether there is a God is a "why" question about the whole of reality, and that calls for philosophy, history and personal experience alongside science.
