Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in glaciers that can be counted back 740,000 years. Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years. Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old. (Updated April 16, 2012)

Because evolution is a challenging subject, many Christians are tempted to simply ignore or reject it. Yet considering evolutionary creation has important benefits for Christians both in our relationship with the Creator, and with our relationships with other people—believers and non-Christians alike. First, Christians should study evolution because (like all the natural sciences) it is the study of God’s creation. Creation itself is a complementary revelation to what is communicated in the Scriptures, and through it God shows how and when he brought about life, to his honor and glory. Studying the creation is also an invitation into a deeper understanding of the attributes and character of Father, Son and Spirit. Second, considering evolutionary creation aids the Church in its gospel mission, supporting young Christians in their faith, helping answer critics, and equipping us to engage effectively in the wider culture. An anti-evolution attitude can harm Christian young people by presenting them with a false choice between pursuing science OR holding to faith. Similarly, a hostile attitude towards evolution can hinder evangelism when seekers hear that they must reject science to follow Christ. On the other hand, studying evolution as a God-ordained process helps Christians refute arguments that science encourages an atheistic worldview. Furthermore, as the church engages front-page issues raised by the rapid growth in science, medicine, and technology, a Christ-centered voice in such areas as bioethics will be stronger if based on a thorough understanding of the natural sciences, including evolution.

NASA astronomer Jennifer Wiseman asserts that studying creation can show us the nature of God; science can inform us of what we need to do as stewards of God’s creation; understanding the natural world gives us a deeper knowledge of Jesus Christ; and science can give us a better understanding of ourselves. This essay was presented at the November 2009 Theology of Celebration Workshop.

Hastings provides a biblical and theological basis for healthy and fruitful dialogue on the theology and science of origins.

Geologists Davidson and Wolgemuth address the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.

Genesis 6-9 tells the fascinating story of Noah, the Ark, and the Flood. Some Christians interpret the text to mean that the biblical flood must have covered the entire globe. They also work to explain the evidence in rocks and fossils in terms of this world-wide flood. Other Christians do not feel the text requires that the flood be global, but could have covered the small region of earth known to Noah. The scientific and historical evidence does not support a global flood, but is consistent with a catastrophic regional flood. Beyond its place in history, the Genesis flood teaches us about human depravity, faith, obedience, divine judgment, grace and mercy.

In this essay, Hastings looks at “front edge” areas for promoting healthy dialogue in the field of science and Christian theology, areas which are specifically theological in nature.

A common argument against biological evolution is that the theory contradicts the second law of thermodynamics. The second law says that disorder, or entropy, always increases or stays the same over time. How then can evolution produce more complex life forms over time? The answer is that the second law is only valid in closed systems with no external sources of energy. Since the Earth receives continual energy from the Sun, the second law does not apply.

Fine-tuning refers to the surprising precision of nature’s physical constants, and the beginning state of the Universe. To explain the present state of the universe, even the best scientific theories require that the physical constants of nature and the beginning state of the Universe have extremely precise values.
