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)

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.

Finding the best interpretation of a scripture passage can be a daunting task. C.S. Lewis advises us to “Look. Listen. Receive.” A good approach is to seek the intended meaning for the original audience before considering what it means for us today. Clues to the original intended meaning can be found in the style of language, the genre of literature, the original audience, and the historical and cultural context. By studying these things, we avoid projecting modern ideas (like science) onto the text.

Darwin developed his theory of evolution by looking at scientific evidence available in the mid-1800s. Since then, the whole field of genetics has developed, adding a powerful independent line of evidence in support of evolution. Genes show how the physical traits of living things are handed down and modified from one generation to the next. By comparing the DNA of many organisms, scientists can map the relationships between species. This map is in remarkable agreement with Darwin’s predictions. The structure of chromosomes and particular genetic sequences point to the conclusion not just of common design, but common descent as well.

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.
