significant parts of the code, which is in the genes, it can cause a disease such as sickle-cell anaemia or even death. Yet even the best and most intelligent typist in the world couldn’t come close to making only one mistake per 10 billion letters, far from it. Is it rational to believe this all came about by a random accident?
The copying mechanism of DNA, to meet maximum effectiveness, requires the number of letters in each “word” to be an even number. Of all possible mathematical combinations, the ideal number for storage and transcription has been calculated to be four letters. This is exactly what has been found in the genes of every living thing on earth, a four-letter digital code. The probability of this happening by chance must be so small as to make it impossible.
One of the discoverers of the genetic code, Francis Crick, after decades of work on deciphering it, admitted that “an honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going” (Life Itself, 1981, p. 88).
It doesn’t take a great deal of thought to see that much more than natural processes would be needed to span the vast difference in chemistry and complexity to form DNA containing billions of coded amino acids and then from DNA to form a living cell.
The origin of life from inorganic molecules is so improbable some have proposed Extraterrestrial origins – delivery by objects (eg carbonaceous chondrites) or by gravitational attraction of organic molecules or primitive life-forms from space but this still doesn’t answer
