"The exact contrary of what is generally believed is often the truth."
óJean de la Bruyere (17th century)
Even though the large majority of modern scientists still embrace an evolutionary view of origins, there is a significant and growing number of scientists who have abandoned evolution altogether and have accepted creation instead.1 This phenomenon of recent times has occurred not only because many scientists recognize the dearth of evidence from paleontology, biology, and other fields to support evolution, but also due to the realization that the world around us is incredibly complex and shows so many signs of design that it cries out for an Intelligent Designer. Man shares with animals the ability to integrate sensory information and to direct motor responses through a command center called the brain. In higher vertebrates, the brain has the ability to learn, and, in the case of humans, to think. The very fact that man possesses the capacity to even think about thinking sets him further apart from animals. So, too, does his brain's incredibly complex structure, which makes thinking possible.
The adult brainóweighing only about three pounds and averaging about 1400 cubic centimetersócontains about ten billion (1010) neurons. The neuron (or nerve cell) is the basic unit of the brain. Each contains branching fibers, called dendrites, and each neuron is in dendritic contact with as many as 10,000 other neurons. Amazingly, the total number of neuron interconnections (also called "bits") is approximately 1000 trillion (1015), and if the dendritic connections were laid end to end, they would circle the earth more than four times.
To put this in another perspective, one could compare the human brain to the most sophisticated of computersóthe supercomputer. The Cray-2 Supercomputer has a speed of 109 computations per second. More impressively, the brain's speed is perhaps 1015. Furthermore, the Cray-2 has a storage capacity of 1011 bits, as compared to 1014 bits in the brain, making the brain equivalent to 1,000 supercomputers.2 Oxford Professor Roger Penrose, evolutionist and author of the 1989 book, The Emperor's New Mind, cautions, however, against stating that the human brain is just a complex computer or that a computer will ever be able to think (i.e., artificial intelligence): "The very fact that the mind leads us to truths that are not computable convinces me that a computer can never duplicate the mind."3 The brain's sophistication has also prompted prolific science writer (and evolutionist) Isaac Asimov to acknowledge that "in Man is a three-pound brain which, as far as we know, is the most complex and orderly arrangement of matter in the universe."4 In his iconoclastic volume, Evolution: A Theory in Crisis, evolutionist Michael Denton has offered the following descriptive observation and analogy regarding the brain's 1015 connections:
Numbers in the order of 1015 are of course completely beyond comprehension. Imagine an area about half the size of the USA (one million square miles) covered in a forest of trees containing ten thousand trees per square mile. If each tree contained ten thousand leaves, the total number of leaves in the forest would be 1015, equivalent to the number of connections in the human brain.5
Although Dr. Denton is not a creationist, he argues a good case against the random chance (mindless) processes of evolution bringing about higher forms of life and a correspondingly complex brain, noting that the human brain contains a "forest of fibers [which] is not a chaotic random tangle but a highly organized network . . . [with] communication channels following their own specially ordained pathways through the brain"6 (emphasis ours). Denton also concludes that it "would take an eternity" for engineers to assemble an object remotely resembling the brain, using the most sophisticated engineering techniques.7 Not only does the incredible design of the brain point to a Master Designer, but so, too, does the Law of Cause and Effect. Simply put, this law states that every phenomenon is an effect of a cause, and that no effect can be measurably greater than its cause. Therefore, using causal reasoning, the first cause of intelligence must be of supreme intelligence.
#1 By evolution, we mean "macroevolution," i.e., molecules-to-man evolution; we do not mean microevolution (variation, adaptation, which is not "vertical" in direction).
