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. (more…)
