Stanley Miller with his experimental apparatus.

The most generally respected study on the origin of life is the Miller experiment conducted by the American researcher Stanley Miller in 1953. (The experiment is also known as the "Urey-Miller experiment" because of the contribution of Miller's instructor at the University of Chicago, Harold Urey.) This experiment is the only "evidence" evolutionists have with which to allegedly prove the "chemical evolution thesis"; they advance it as the first stage of the supposed evolutionary process leading to life. Although nearly half a century has passed, and great technological advances have been made, nobody has made any further progress. In spite of this, Miller's experiment is still taught in textbooks as the evolutionary explanation of the earliest generation of living things. That is because, aware of the fact that such studies do not support, but rather actually refute, their thesis, evolutionist researchers deliberately avoid embarking on such experiments.

Stanley Miller's aim was to demonstrate by means of an experiment that amino acids, the building blocks of proteins, could have come into existence "by chance" on the lifeless earth billions of years ago. In his experiment, Miller used a gas mixture that he assumed to have existed on the primordial earth (but which later proved unrealistic), composed of ammonia, methane, hydrogen, and water vapor. Since these gases would not react with each other under natural conditions, he added energy to the mixture to start a reaction among them. Supposing that this energy could have come from lightning in the primordial atmosphere, he used an electric current for this purpose.

Miller heated this gas mixture at 100°C for a week and added the electrical current. At the end of the week, Miller analyzed the chemicals which had formed at the bottom of the jar, and observed that three out of the 20 amino acids which constitute the basic elements of proteins had been synthesized.

This experiment aroused great excitement among evolutionists, and was promoted as an outstanding success. Moreover, in a state of intoxicated euphoria, various publications carried headlines such as "Miller creates life." However, what Miller had managed to synthesize was only a few inanimate molecules.

Encouraged by this experiment, evolutionists immediately produced new scenarios. Stages following the development of amino acids were hurriedly hypothesized. Supposedly, amino acids had later united in the correct sequences by accident to form proteins. Some of these proteins which emerged by chance formed themselves into cell membrane-like structures which "somehow" came into existence and formed a primitive cell. These cells then supposedly came together over time to form multicellular living organisms.

However, Miller's experiment has since proven to be false in many respects.
