Miller's experiment sought to prove that amino acids could form on their own in primordial earth-like conditions, but it contains inconsistencies in a number of areas:
1. By using a mechanism called a "cold trap", Miller isolated the amino acids from the environment as soon as they were formed.
Had he not done so, the conditions in the environment in which the amino acids were formed would immediately have destroyed these molecules.
Doubtless, this kind of a conscious mechanism of isolation did not exist on the primordial earth. Without such a mechanism, even if one amino acid were obtained, it would immediately have been destroyed. The chemist Richard Bliss expresses this contradiction by observing that "Actually, without this trap, the chemical products would have been destroyed by the energy source."116
And, sure enough, in his previous experiments, Miller had been unable to make even one single amino acid using the same materials without the cold trap mechanism.
2. The primordial atmospheric environment that Miller attempted to simulate in his experiment was not realistic.
In the 1980s, scientists agreed that nitrogen and carbon dioxide should have been used in this artificial environment instead of methane and ammonia. After a long period of silence, Miller himself also confessed that the atmospheric environment he used in his experiment was not realistic.117
So why did Miller insist on these gasses? The answer is clear: without ammonia, it was impossible to synthesise any amino acid. Kevin Mc Kean talks about this in an article published in Discover magazine:
Miller and Urey imitated the ancient atmosphere on the Earth with a mixture of methane and ammonia. According to them, the Earth was a true homogeneous mixture of metal, rock and ice. However in the latest studies, it has been understood that the Earth was very hot at those times, and that it was composed of melted nickel and iron. Therefore, the chemical atmosphere of that time should have been formed mostly of nitrogen (N2), carbon dioxide (CO2) and water vapour (H2O). However these are not as appropriate as methane and ammonia for the production of organic molecules.118
The American scientists J.P. Ferris and C.T. Chen repeated Miller's experiment with an atmospheric environment that contained carbon dioxide, hydrogen, nitrogen, and water vapour, and were unable to obtain even a single amino acid molecule.119
3-Another important point that invalidates Miller's experiment is that there was enough oxygen to destroy all the amino acids in the atmosphere at the time when they were thought to have been formed.
This fact, overlooked by Miller, is revealed by the traces of oxidised iron and uranium found in rocks that are estimated to be 3.5 billion years old.120
There are other findings showing that the amount of oxygen in the atmosphere at that time was much higher than originally claimed by evolutionists. Studies also show that at that time, the amount of ultraviolet radiation to which the earth was then exposed was 10,000 times more than evolutionists' estimates. This intense radiation would unavoidably have freed oxygen by decomposing the water vapour and carbon dioxide in the atmosphere.
This situation completely negates Miller's experiment, in which oxygen was completely neglected. If oxygen had been used in the experiment, methane would have decomposed into carbon dioxide and water, and ammonia into nitrogen and water. On the other hand, in an environment where there was no oxygen, there would be no ozone layer either; therefore, the amino acids would have immediately been destroyed, since they would have been exposed to the most intense ultraviolet rays without the protection of the ozone layer. In other words, with or without oxygen in the primordial world, the result would have been a deadly environment for the amino acids.
4. At the end of Miller's experiment, many organic acids had been formed with characteristics detrimental to the structure and function of living things. If the amino acids had not been isolated, and had been left in the same environment with these chemicals, their destruction or transformation into different compounds through chemical reactions would have been unavoidable.
Moreover, a large number of right-handed amino acids were formed at the end of the experiment.121The existence of these amino acids refuted the theory even within its own terms because right-handed amino acids cannot function in the composition of living organisms. To conclude, the circumstances in which amino acids were formed in Miller's experiment were not suitable for life. In truth, this medium took the form of an acidic mixture destroying and oxidising the useful molecules obtained.
All these facts point to one firm truth: Miller's experiment cannot claim to have proved that living things formed by chance under primordial earth-like conditions. The whole experiment is nothing more than a deliberate and controlled laboratory experiment to synthesise amino acids. The amount and types of the gases used in the experiment were ideally determined to allow amino acids to originate. The amount of energy supplied to the system was neither too much nor too little, but arranged precisely to enable the necessary reactions to occur. The experimental apparatus was isolated, so that it would not allow the leaking of any harmful, destructive, or any other kind of elements to hinder the formation of amino acids. No elements, minerals or compounds that were likely to have been present on the primordial earth, but which would have changed the course of the reactions, were included in the experiment. Oxygen, which would have prevented the formation of amino acids because of oxidation, is only one of these destructive elements. Even under such ideal laboratory conditions, it was impossible for the amino acids produced to survive and avoid destruction without the "cold trap" mechanism.
In fact, by his experiment, Miller destroyed evolution's claim that "life emerged as the result of unconscious coincidences". That is because, if the experiment proves anything, it is that amino acids can only be produced in a controlled laboratory environment where all the conditions are specifically designed by conscious intervention. That is, the power that brings about life cannot be by unconscious chance but rather by Creation.
The reason evolutionists do not accept this evident reality is their blind adherence to prejudices that are totally unscientific. Interestingly enough, Harold Urey, who organised the Miller experiment with his student Stanley Miller, made the following confession on the subject:
All of us who study the origin of life find that the more we look into it, the more we feel it is too complex to have evolved anywhere. We all believe as an article of faith that life evolved from dead matter on this planet. It is just that its complexity is so great, it is hard for us to imagine that it did.122
