The Age of the Earth
The scientific consensus on the age of the universe and the earth is based on multiple independent lines of evidence that converge on the same conclusion. Cosmological observations point to an age of approximately 13.8 billion years for the universe. Radiometric dating of the oldest rocks and meteorites, combined with geological evidence, points to an age of approximately 4.5 billion years for the earth. These are not estimates based on a single measurement or a single method. They are the result of multiple independent investigations using different physical principles that all arrive at the same range of ages.
Old earth creationism accepts the scientific evidence for the age of the universe and the earth while maintaining that God specially created distinct biological kinds at various points in earth's history rather than through an unbroken evolutionary process. Day-age theory holds that the "days" of Genesis 1 refer to geological epochs rather than 24-hour periods. Each of these approaches attempts to harmonize the scientific evidence with a particular reading of Genesis without accepting biological evolution.
Young earth creationists must argue either that the scientific dating methods are fundamentally flawed or that God created the earth with the appearance of age. The "appearance of age" argument has been criticized even by some young earth advocates as theologically problematic: it seems to make God the author of deception, creating physical evidence that points systematically toward a false conclusion. The argument that radiometric dating is fundamentally unreliable has not gained traction in the scientific community, including among Christian scientists.
The age of the earth is ultimately a scientific question, and the scientific evidence is clear and convergent. The theological question is whether accepting that evidence requires abandoning any essential Christian commitment - and the answer, for the great majority of Christian scientists and theologians, is no. The doctrine of creation is not primarily a claim about when things happened. It is a claim about why they exist at all, what their ultimate source is, and what their purpose is. Those claims are unaffected by the age of the earth.
