The theory of biological evolution is the current scientific explanation of life on earth. This assumes that life has developed from simple to complex over time. So if we extrapolate backwards in time, we eventually reach the first living cell. As this theory relies on natural selection, it only operates on populations of species, and not on the original members of the species (like the first living cell). So where did the original living cell (which is assumed to be the ancestor of all life on earth) come from? It’s assumed that life originated from non-living chemicals via chemical evolution. Did you know that this theory includes a miracle that can’t be explained by modern science? According to the Macquarie dictionary, a miracle is “an effect in the physical world which surpasses all known human or natural powers and is therefore ascribed to supernatural agency”.
Complexity of life
In the 19th century many people believed the theory of spontaneous generation; that life arose from non-living matter. This is understandable because they knew little about the cell’s structure.
But today we know that even the simplest living single-cell organism is extremely complex, including numerous, complex machines and instructions to build them, all stored in a way that can be both decoded for use by the organism and passed on to offspring. In fact, a single cell is vastly more complicated than anything human minds have ever engineered.
Scientists agree that the first living cell possessed DNA, RNA and proteins, a universal genetic code, ribosomes (the protein-building factories), ATP and a proton-powered enzyme for making ATP. The detailed mechanisms for reading off DNA and converting genes into proteins were also in place. So it must have been like a modern cell. This is called “irreducible complexity” – all these components are required for a cell to function and reproduce. Because this complexity could never arise by chance, it was either designed or it was a miracle. Life can’t evolve from chemicals by chance.
Living cells are comprised of hardware and software. The software is information stored in the DNA molecule. Enormous amounts of coded information are stored in DNA. Each of the thousands of genes on a DNA molecule contains instructions necessary to make a specific protein that, in turn, is needed for a specific biological function. All the detailed chemical and structural complexity associated with the metabolism, repair, specialized function, and reproduction of each living cell is a realization of the coded messages stored in its DNA. This information is read by a RNA molecule and used to make proteins. But the RNA is also encoded in the DNA, which is a “chicken and egg” problem! And the energy to do this is produced by the nano-motor ATP synthase which is also encoded on the DNA and is decoded by machines needing ATP! So there are multiple “chicken and egg” problems.
ATP synthase is one of many enzymes which are biological catalysts that speed up vital chemical reactions. Without them many reactions essential for life would be far too slow for life to exist. These enzymes, as well as other processes, must exist in the first replicating cell in order for that cell to survive and pass on the DNA, and the DNA must code for the proteins required for those processes!
The naturalistic explanation of the origin of life from non-living matter has a problem because there is no known natural process which can cause information to originate by itself in matter. Information cannot arise by naturalistic processes. The DNA code within all plant and animal cells is vastly more compact than any computer chip ever made. Therefore, the originator of the information must be supremely intelligent.
The theory of the chemical evolution of life assumes that this information is produced by physical processes. But the chemical workings of the cell are controlled by information which does not reside in the atoms and molecules of that cell. For example, the order of the DNA base pairs (like letters in a message) cannot be predicted from the chemical characteristics of the individual base pairs (letters). And as there is no law of physics about creating information from nothing, this assumption is equivalent to a miracle.
Because of the impossibility of chemical evolution on earth, some have suggested that life began in outer space. In order to be able to start the evolution of life on earth, it has been proposed that life was seeded on earth by meteorites, comets or extra-terrestrials. Of course, there is no evidence of this and it doesn’t answer the question of the origin of life. It just transfers it to another place in the universe.
Besides the above, the theory of chemical evolution goes against the law of biogenesis (Appendix A).
And the Milller-Urey experiment, which is often quoted to support the theory of chemical evolution didn’t produce the amino acids necessary for life (Appendix B).
The theory of chemical evolution of life on earth involves a miracle that can’t be explained by operational science. This is a fatal flaw for a model that doesn’t accept miracles! But the theory of biological evolution can’t start without this miracle.
I’m skeptical of a model that claims to be based on naturalism, yet requires miracles! It’s like pulling a rabbit out of a hat! This kind of historical science isn’t consistent.
But the Bible is consistent when it attributes the creation of plant, animal and human life to the all-powerful spiritual God (Gen. 1:11-12; 20-27).
Appendix A: The law of Biogenesis
The law of biogenesis says that all life comes from life. Lois Pasteur disproved the idea of spontaneous generation (that life could come from non-living material). He demonstrated that life does not arise from matter that has not been contaminated by existing life. This means that life has never come from non-life.
Appendix B: The Miller-Urey experiment
This was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth. In this experiment a mixture of water, methane, ammonia and hydrogen was exposed to an electrical current. It resulted in the production of amino acids that were claimed to be the precursors of life. But this experiment relied on the lack of oxygen in the atmosphere, whereas more recent studies indicate that oxygen was present in the earth’s atmosphere earlier than had been believed. And if there was no oxygen, there would be no ozone and the amino acids would be destroyed by ultraviolet solar radiation. Also, they had to isolate the amino acids from the mixture to stop them being destroyed (by hydrolysis, for example). And the amino acids produced were a mixture of left-handed and right-handed, which would be detrimental to life because all the proteins in animals and plants are only made up of left-handed amino acids. So this experiment didn’t produce the amino acids necessary for life.
