    Coal formation is a very controversial issue in the creation vs. evolution argument, and one that has been under debate for many years. Secular (or uniformitarian) geologists traditionally teach that coal is formed at the bottom of swamps over millions of years of uniform peat deposition. This theory, known as the autochthonous theory states that coal is formed by slow peat accumulation, and
