Spontaneous generation is a theory that living creatures came from non-living materials. The doctrine of spontaneous generation was coherently synthesized by Aristotle, a Greek philosopher who complied and expanded the work of prior philosophers and various ancient explanations of the appearance of organisms; it held sway for two thousand years. Many scientists believed in spontaneous generation. They thought that if a pile of old clothes were left in a corner, it would breed mice! The proof was that, upon later returning to the clothes, mice would frequently be found there. Today it is generally accepted to have been decisively dispelled during the 19th century by the experiments of Louis Pasteur.
Louis Pasteur (1822-1895) was a genuine scientist. In the process of studying fermentation, he performed his famous 1861 experiment, in which he disproved the theory of spontaneous generation. He proved that life cannot arise from non-living materials. He believed in Biogenesis, the scientific name for the important biological truth that he confirmed, that life can only come from life. "Biogenesis is a term in biology that is derived from two Greek words meaning life and birth. According to the theory of biogenesis, living things descend only from living things. They cannot develop spontaneously from non-living materials. Until comparatively recent times, scientists believed that certain tiny forms of life, such as bacteria, arose spontaneously from non-living substances." (Biogenesis, "World Book Encyclopedia, p. B-242 (1972 edition).
Louis Pasteur concluded from his experiment that only God could create living creatures. But the modern evolutionary theory continues to be based on that out-dated theory disproved by Pasteur: spontaneous generation (life arises from non-life). Why? Because it is the only basis on which evolution could occur. J. Edison Adams from his book, "Plants: An Introduction to Modern Biology, 1967, p.585, said, "With spontaneous generation discredited by Pasteur, biologists were left with no theory of the origin of life at all."
