Nature suggests the existence of God because we find advanced design in nature, and we know that advanced design is produced by the actions of an intelligent mind - so there must have been a Creator who designed things in nature. The theory of evolution claims that systems in nature that appear to be designed by a Creator actually arose through natural processes. I will show below that this claim is not reasonable - you cannot believe it without blind faith.
I will describe design in nature through four properties. Although they are all inter-related, I've listed them down in four different categories for clarity and inclusiveness.
"To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a billion times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see is an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. I we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity. We would see endless highly organized corridors and conduits branching in every direction away from the perimeter of the cell, some leading to the central memory bank in the nucleus and others to assembly plants and processing units. The nucleus itself would be a vast spherical chamber more than a kilometer in diameter, resembling a geodesic dome inside of which we would see, all neatly stacked together in ordered arrays, the miles of coiled chains of DNA molecules....Is it really credible that random processes could have constructed a reality, the smallest element of which - a functional protein or gene - is complex beyond our own creative capacities, a reality which is the very anti-thesis of chance, which excels in every sense anything produced by the intelligence of man?" - Michael Denton, Evolution: A Theory in Crisis. Denton was a molecular biologist and non-creationist.Here are some examples of sophisticated systems in living things at a macroscopic level:-
It is only to be expected that sophisticated systems should result in incredible functionality. Here are some examples:-
The bacterial flagellum (a whip or blade that bacteria use to propel themselves, with an attached rotor) shown in the image has the following features:-
One hair of a gecko's foot can support an ant's weight. A million of them (which would fit in a square inch) could support a child's weight. Moreover, these hairs repel dirt (unlike ordinary adhesive tape!)
The dolphin’s sonar system is so precise that it’s the envy of the U.S. Navy. It can detect a fish the size of a golf ball 230 feet (70m) away. It took an expert in chaos theory to show that the dolphin’s “click” pattern is mathematically designed to give the best information.
The sonar echo-locating system of bats works on clicks emitted by the bats. Bats are able to vary the time interval between successive clicks (closely spaced clicks are needed when the bat nears its prey), and also the gain in the echo signals entering their ears (less gain is needed for signals reflected by nearby objects, otherwise the bat would become deaf). Bats can locate a minnow's fin as fine as a human hair, extending only 2 mm above the water surface.
Dragonflies can fly forward and backward. They literally turn on a dime. Their unique eyes (with over 30,000 lenses) give them the ability to see 360 degrees around their body and they need this, because dragonflies can literally execute a hairpin turn at 100 kilometers per hour. At that speed a dragonfly can experience a G-force of about 25 times the gravity of earth. In comparison, the most gravity force that a human fighter pilot can sustain without blacking out is about nine Gs.
Evolutionary responses: Evolutionists have responded to the information argument with the following:-
"It is, for example, impossible for evolution to account for the fact than one single cell can carry more data than all the volumes of the Encyclopedia Britannica put together...It now seems to me that the findings of more than fifty years of DNA research have provided materials for a new and enormously powerful argument to design.” – Anthony Flew, Professor of Philosophy, author, and debater; Antony Flew was an atheist debater but abandoned atheism after considering this evidence.
Evolutionists would have us believe that woodpeckers share a common ancestry with other birds. Okay, why should some of these birds start banging their heads in trees?! What’s the survival value of that? By the way, the woodpecker hits really hard, and today’s woodpeckers are able to get away with it because of special shock-absorbing tissue that they have. So, the tissue evolved on its own and then these poor birds started banging their heads into trees to exercise their tissue! When the woodpecker bangs it’s beak into a tree, the bark comes out, and there are insects beneath that the woodpecker wants to eat. Needless to say, the insects try to go further in and avoid the woodpecker’s beak. What is our bird going to do now? Pull out its tongue! Woodpeckers have a long tongue that reaches out to the insect. What’s the use of making contact with the insect if you can’t get it in? Well? Their tongue is not just long but sticky! The insect sticks to the tongue and is brought into the mouth of the woodpecker. Good job done, but where is the woodpecker going to keep that tongue once the meal is done? It has a special coiling arrangement in its mouth for the purpose! Think of all the components of the system:
Another example of irreducible complexity in nature: The dragonfly cannot fly without its spectacular vision. But this vision could not have evolved earlier because it is of negligible advantage to a non-flier (so natural selection would not propagate it). Could its vision and flight capability have evolved gradually and simultaneously? This requires two long synchronized series of random genetic changes that are unrelated (at the genetic level) - wishful thinking.
Irreducibly complex systems cannot arise via mutations and natural selection because even if there is a mutation in the right direction, natural selection has no reason to select the mutant organism in favor of the others - only after the system is fully functional does it confer any survival advantage.
The pioneering work in irreducible complexity is Michael Behe, Darwin's Black Box: the Biochemical Challenge to Evolution. New York: Touchstone, 1996. The examples of irreducible design given by Michael Behe are:-
Evolutionary responses: Evolutionists have responded to the argument of irreducible complexity with the following:-
However, both these explanations are just-so stories because no real-world examples were given. Thus, irreducible complexity remains strong evidence for a Creator.
Design in nature shouts out that God exists! We are privileged to live in an age when technology has made it possible for man to get a much better glimpse into this design than was possible before.
"God's anger is manifest against people who suppress the truth in unrighteousness. The attributes of God such as His eternal power are obvious from the world around us. Hence, those who do not acknowledge God are without excuse. " - Romans 1:18-20, paraphrased.
