How old is the Earth?

A theory is not a random guess. It is an explanation built to make sense of what has been observed. People gather evidence, look for patterns, test ideas, and then propose a framework that explains what they think the evidence means.That matters because observation and interpretation are not always the same thing. Two people can agree that rocks exist, that layers exist, that fossils exist, and that measurements can be taken — and still disagree about what those things mean.In science, theories are meant to explain data. They are not the data itself. That is why debates can happen even when people are looking at the same world. The question is not only, “What do we see?” but also, “What is the best explanation for what we see?”When Christians talk about Scripture and science, this distinction matters. A person may believe the world shows real order, real evidence, and real patterns, but…

Arthur Holmes was an English geologist who worked extensively with radiometric dating, a method used to estimate the ages of rocks based on measured decay rates. He also served as Regius Professor of Geology at the University of Edinburgh and contributed to the development of long-age timelines within geology.Holmes worked within the scientific framework of his field and helped advance techniques that assign numerical ages to rock layers. His work is commonly cited in historical summaries as an early step in establishing age estimates that extend far beyond earlier, shorter timelines.At the same time, it is important to understand what these methods represent. Radiometric dating relies on a set of underlying assumptions, including initial conditions, closed systems, and consistent decay rates over time. These assumptions are discussed and evaluated in ongoing debates about how such…
