Composition of Proteins

Let us now examine in detail why the evolutionist scenario regarding the formation of proteins is impossible. Life on Earth is built from billions of different proteins. Proteins are built from amino acids. Key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). About 500 naturally occurring amino acids are known (though only 20 appear in the genetic code).

Even the correct sequence of the right amino acids is still not enough for the formation of a functional protein molecule. In addition to these requirements, each of the 20 different types of amino acids present in the composition of proteins must be left-handed. There are two different types of amino acids (as of all organic molecules) called "left-handed" and "right-handed." The difference between them is the mirror-symmetry between their three dimensional structures, which is similar to that of a person's right and left hands. The proteins in living creatures consist only of left-handed amino acids.

Amino acids of either of these two types can easily bond with one another. But one astonishing fact that has been revealed by research is that all the proteins in plants and animals on this planet, from the simplest organism to the most complex, are made up of left-handed amino acids. If even a single right-handed amino acid gets attached to the structure of a protein, the protein is rendered useless.

Let us for an instant suppose that life came about by chance as evolutionists claim it did. In this case, the right- and left-handed amino acids that were generated by chance should be present in roughly equal proportions in nature. Therefore, all living things should have both right- and left-handed amino acids in their constitution, because chemically it is possible for amino acids of both types to combine with each other. However, as we know, in the real world the proteins existing in all living organisms are made up only of left-handed amino acids.

The question of how proteins can pick out only the left-handed ones from among all amino acids, and how not even a single right-handed amino acid gets involved in the life process, is a problem that still baffles evolutionists. Such a specific and conscious selection constitutes one of the greatest problems facing the theory of evolution.

Moreover, this characteristic of proteins makes the problem facing evolutionists with respect to "chance" even worse. In order for a "meaningful" protein to be generated, it is not enough for the amino acids to be present in a particular number and sequence, and to be combined together in the right three-dimensional design. Additionally, all these amino acids have to be left-handed: not even one of them can be right-handed. Yet there is no natural selection mechanism which can identify that a right-handed amino acid has been added to the sequence and recognize that it must therefore be removed from the chain. This situation once more eliminates for good the possibility of coincidence and chance.

The Britannica Science Encyclopaedia, which is an outspoken defender of evolution, states that the amino acids of all living organisms on earth, and the building blocks of complex polymers such as proteins, have the same left-handed asymmetry. It adds that this is tantamount to tossing a coin a million times and always getting heads. The same encyclopaedia states that it is impossible to understand why molecules become left-handed or right-handed, and that this choice is fascinatingly related to the origin of life on earth.

One way to look at this is to compare it to a coin toss. If a coin always turns up heads when tossed a million times, is it more logical to attribute that to chance, or else to accept that there is conscious intervention going on? The answer should be obvious. However, obvious though it may be, evolutionists still take refuge in coincidence, simply because they do not want to accept the existence of conscious intervention.


Another way to look at this is to compare it to building a necklace. This is like trying to make an all white perl necklace from black and white pearls. Each 'strand' is about 146 perls (amino acids) long. The resulting odds of forming ONLY one 'chiral protein molecular strand' by randomly selecting from a vat of right and left handed amino acid molecules are 1:9 × 10^43. (1:2^146) The odds for one entire hemoglobin molecule considering all four strands is 1:6.3x10^175. (1 followed by 175 zeros.) Essentially one in infinity. (A googol is 10 to the 100th power which is 1 followed by 100 zeros. A googol is larger than the number of elementary particles in the universe, which amount to only 10 to the 80th power.) These kind of odds will never happen and we are still only talking about one molecule out of billions of different types of proteins. Wash, rinse, repeat a few billion times and what do you get? What is infinity times a few billion infinities? Flat out impossible theory that has never happened - nor will it ever happen.


A situation similar to the left-handedness of amino acids also exists with respect to nucleotides, the smallest units of the nucleic acids, DNA and RNA. In contrast to proteins, in which only left-handed amino acids are chosen, in the case of the nucleic acids, the preferred forms of their nucleotide components are always right-handed. This is another fact that can never be explained by chance.


In conclusion, it is proven beyond a shadow of a doubt by the probabilities we have examined that the origin of life cannot be explained by chance if we attempt to calculate the probability of an average-sized protein consisting of 400 amino acids being selected only from left-handed amino acids. Just for a comparison, let us remember that the number of electrons in the universe is a much smaller number. The probability of these amino acids forming the required sequence and functional form would generate much larger numbers. If we add these probabilities to each other, and if we go on to work out the probabilities of even higher numbers and types of proteins, the calculations become inconceivable.

In short - this is flat out impossible and you should not waste your time with this nonsense.
