Chemical Elements of Life 1

The chemical evolution of life is ridiculously improbable. What could improve the odds? One should begin with an earth having high concentrations of the key elements comprising life, such as carbon, oxygen, and nitrogen (a). However, the closer one examines these elements, the more unlikely evolution appears.

Carbon. Rocks that supposedly preceded life have very little carbon (b). One must imagine a toxic, carbon-rich atmosphere to supply the needed carbon if life evolved. For comparison, today’s atmosphere holds only 1/80,000 of the carbon that has been on the earth’s surface since the first fossils formed.

Oxygen. No evolutionary theory has been able to explain why earth’s atmosphere has so much oxygen. Too many substances should have absorbed oxygen on an evolving earth (c). Besides, if the early earth had oxygen in its atmosphere, compounds (called amino acids) needed for life to evolve would have been destroyed by oxidation (d). But if there had been no oxygen, there would have been no ozone (a form of oxygen) in the upper atmosphere. Without ozone to shield the earth, the sun’s ultraviolet radiation would quickly destroy life (e). The only known way for both ozone and life to be here is for both to come into existence simultaneously—in other words, by creation.

a. The four most abundant chemical elements, by weight, in the human body are oxygen (65%), carbon (18%), hydrogen (10%), and nitrogen (3%).

b. Carbon is only the 18th most abundant element, by weight, in the earth’s crust. Furthermore, almost all carbon is tied up in organic matter, such as coal and oil, or in sediments deposited after life began, such as limestone or dolomite.

c. “The cause of the initial rise in oxygen concentration presents a serious and unresolved quantitative problem.” Leigh Van Valen, “The History and Stability of Atmospheric Oxygen,” Science, Vol.*171, 5 February 1971, p.*442.

d. Since 1930, knowledgeable evolutionists have realized that life could not have evolved in the presence of oxygen. [See]*If no oxygen was in the atmosphere as life evolved, how did the atmosphere get its oxygen?

Cyanobacteria break down carbon dioxide and water and release oxygen. In 1987, William J. Schopf claimed that he and his graduate student had discovered fossils of 3.4-billion-year-old cyanobacteria. This, he said, is how the atmosphere gained its oxygen after these bacteria—shielded by a shallow sea from ultraviolet radiation—evolved. Evolutionists eagerly accepted this long-awaited discovery as a key part of their theory of how life evolved.

Schopf’s former graduate student and other experts have now charged Schopf with withholding evidence that those fossils were not cyanobacteria. Most experts feel betrayed by Schopf, who now accepts that his “specimens were not oxygen-producing cyanobacteria after all.” [See Rex Dalton, “Squaring Up over Ancient Life,” Nature, Vol.*417, 20*June 2002, pp.*782–784.] A foundational building block in the evolution story—that had become academic orthodoxy—has crumbled.

e . Hitching, p.*65.
