Lyell's extreme form of uniformitarianism would have required a perfect balance between heat production and heat loss.Kelvin argued that this was physically impossible (the concept is akin to a perpetual motion machine).Strata Thickness- In the late 1800s, a British geologist estimated that 75 million years has lapsed since the beginning of the Cambrian.This estimate was based upon the maximum known thickness of strata (from Cambrian to present) divided by the average rate of sedimentation in modern environments. Joly used the salinity of ocean water to determine the age of the earth.Mountains, erosion, and variations in climate were considered to be punishment for the sins committed by humanity.Buffon's Iron Sphere Experiments- On the basis of iron sphere cooling experiments, Frenchman Georges de Buffon estimated that the Earth would have needed 75,000 years to cool to its present temperature.That is, the earth accreted from small, cold chunks of material and then heated up at a later time.

In particular, it describes a time when God catastrophically destroyed the earth and essentially all its life.With the discovery of radioactivity about a hundred years ago, evolutionists deeply committed to the uniformitarian outlook believed they finally had proof of the immense antiquity of the earth.In particular, they discovered the very slow nuclear decay rates of elements like Uranium while observing considerable amounts of the daughter products from such decay.Chronological Analysis of the Scriptures- Literal interpretation of the scriptures led some people to conclude that the Earth was created approximately 6,000 years old.In fact, Archbishop Usher of Ireland calculated that the Earth was created at 9 AM on It was believed that prior to the Great Flood, Earths surface was flat and its climate was mild.
