Imagine finding a planet where robots are programmed so that they can make other robots just like themselves from raw materials.
Now, imagine an alien scientist visitor coming to the planet and, after many years of studying these robots, the alien scientist visitor comes to the conclusion that since science can explain how these robots work, operate, function, and reproduce there's no reason to believe that there was an ultimate intelligent designer behind them.
The analogy above certainly is not perfect but it is sufficient to reveal the fallacious thinking of those who attack intelligent design behind life and the universe.
Of course, once there is a complete and living cell then the genetic program and complex biological mechanisms exist to direct the formation of more cells. The question is how could life or the cell come into existence naturally when there was no directing mechanism in nature.
Intelligent Design theory does not oppose natural laws but simply states that mere undirected natural laws can never account for the high complexity found in life and the universe.
Chance physical processes can produce some level of order but it is not rational to believe that the highest levels of order in life and the universe are by chance. For example, some amino acids have been shown to be able to come into existence by chance but not more complex molecules or structures such as proteins which require that the various amino acids be in a precise sequence, just like the letters in a sentence. If they're not in the right sequence the protein molecules will not function. A single cell alone has millions of protein molecules!
There is no innate chemical tendency for the various amino acids to bond with one another in a sequence. Any one amino acid can just as easily bond with any other. The only reason at all for why the various amino acids bond with one another in a precise sequence in the cells of our bodies is because they're directed to do so by an already existing sequence of molecules in our genetic code. Without being in a proper sequence protein molecules will not function.
The sequence of molecules in DNA (the genetic code) determines the sequence of molecules in proteins. Furthermore, without DNA there cannot be RNA, and without RNA there cannot be DNA. And without either DNA or RNA there cannot be proteins, and without proteins there cannot be DNA or RNA. They're all mutually dependent upon each other for existence! None of these molecules can "survive" or replicate outside of a complete and living cell. This simply means that DNA ,RNA , and proteins could never have gradually evolved waiting supposedly through hundreds of millions of years to become a complete cell.
If the cell had evolved it would have had to be all at once. A partially evolved cell cannot wait millions of years to become complete because it would be highly unstable and quickly disintegrate in the open environment, especially without the protection of a complete and fully functioning cell membrane.
In nature there are what scientists call right-handed and left-handed amino acids. However, life requires that all proteins be left-handed. So, not only do millions of amino acids have to be in the correct sequence, they also all have to be left-handed. If a right-handed amino acid gets mixed in then the protein molecules won't function. There won't be any life!
Similarly, the nucleic acids in DNA and RNA must be in a precise sequence. The sugar molecules that make-up the various nucleic acids in DNA and RNA must all be right-handed. If a nucleic acid with a left-handed sugar molecule gets into the mix then nothing will work.
The best little article ever written refuting the origin of life by chance is "A Few Reasons an Evolutionary Origin of Life Is Impossible" by scientist and biochemist Dr. Duane T. Gish. Dr. Gish presents "simple" but profound scientific barriers to evolution of life which aren't mentioned or covered in Johnny's high school biology textbook or in college textbooks for that matter. This article is truly great! Dr. Gish's article may be accessed for reading at: http://icr.org/article/3140/ where also links to other articles may be found.
Trust me, Dawkins and all the evolutionists put together can't hold a candle to the scientific genius of Dr. Gish. Just read one of Dr. Gish's books and you'll see why. Dr. Gish has successfully debated hundreds of evolution scientists in secular colleges and universities across the nation over the past two decades, and students have consistently voted him the winner in all of those debates. Don't try looking for this news in the main stream media. You won't find it there anymore than you'll find a half-evolved chipmunk running around in your backyard!
Think about it! If humans must use intelligence to perform genetic engineering, to meaningfully manipulate the genetic code, then what does that say about the origin of the genetic code itself!
Contrary to popular belief, scientists have never created life in the laboratory. What scientists have done is genetically alter or engineer already existing forms of life, and by doing this scientists have been able to produce new forms of life. However, they did not produce these new life forms from non-living matter. Even if scientists ever do produce life from non-living matter it won't be by chance so it still wouldn't help support any argument for evolution.
Even in the recent case, as reported in the news, involving the creation of what is called synthetic (or artificial) life, scientists don't actually create or produce life itself from non-living matter. What scientists do in this case is create (by intelligent design) artificial DNA (genetic instructions and code) which is then implanted into an already existing living cell and, thereby, changing that cell into a new form of life. And, again, even if scientists ever do create a whole living cell from scratch (and not just its DNA) it still would not be by chance but by intelligent design. Synthetic life is another form of genetic engineering. But God was there first. Remember that!
The great British scientist Sir Frederick Hoyle has said that the probability of the sequence of molecules in the simplest cell coming into existence by chance is equivalent to a tornado going through a junk yard of airplane parts and assembling a 747 Jumbo Jet!
Genetic information, like other forms of information, cannot arise by chance, so it is far more logical to believe that the DNA and biological similarities between species are due to a common Designer rather than common ancestry through evolution by way of random mutations. The Creator simply designed similar functions for similar purposes in all the various forms of life.
DNA similarities within a true species can be used to establish relationship because within a true species the various individuals can interbreed, but this not the case across true species. Therefore, similarities across true species cannot be used for establishing biological relationships.
What about natural selection? Natural selection only comes into operation once there is life. Also, natural selection is not a creative force. It is a passive force in Nature. Natural selection has no ability to design or generate new genes or new biological traits.
Natural selection can only "select" from biological variations that are produced and which have survival value. The real issue is what biological variations can be naturally produced. What biological variations are naturally possible? When a biological change or variation occurs within a species and this new variation (such as a change in skin color, etc.) helps that species to survive in its environment then that variation will be preserved ("selected") and be passed on to offspring. That is called "natural selection" or "survival of the fittest". But, neither "natural selection" nor "survival of the fittest" has anything to do with producing biological traits and variations.
The term "natural selection" is simply a figure of speech. Nature, of course, does not do any active or conscious selecting. It is an entirely passive process. Darwin did not realize what produced biological variations. Darwin simply assumed that any kind of biological change or variation was possible in life. However, we now know that biological traits and variations are determined by the genetic code.
Natural selection works with evolution but it is not evolution itself. Again, since natural selection can only "select" from biological variations that are possible, the real question to be asking is what kind of biological variations are naturally possible. How much biological variation (or how much evolution) is naturally possible in Nature?
The evidence from science shows that only microevolution (variations within a biological "kind" such as the varieties of dogs, cats, horses, cows, etc.) is possible but not macroevolution (variations across biological "kinds", especially from simpler kinds to more complex ones). The only evolution that occurs in Nature and which can be studied in Nature is microevolution (or horizontal evolution) but not macroevolution (or vertical evolution). There is no scientific evidence whatsoever that genetic mutations (random changes in the genetic code) caused by various environmental forces such as radiation have any capability to increase the genetic complexity of a species so that macroevolution from earthworm to man would be possible.
It is precisely because they are accidents in the genetic code that almost all true mutations are harmful. Even if a good one occurred for every good one there will be hundreds of harmful ones with the net effect being disastrous for the species as a whole. Most biological variations in species are due to new combinations of already existing genes and not because of mutations which are rare in Nature. A genetic engineer Nature is not!
What about “Junk DNA”? The latest science shows that "Junk DNA” isn't junk after all! It's we who were ignorant of how useful these segments of DNA really are. Recent scientific research published in scientific journals such as Nature has revealed that the "non-coding" segments of DNA are more than just useful; they are vital in regulating gene expression (i.e. how, when, and where) genes are expressed.
As for repetitive structures in DNA, they're not junk either. They may have a “back-up” purpose, like a spare tire in car, which the organism can utilize should it lose genetic material due to damage from random mutations caused by environmental forces.
Another reason for why macroevolution is not possible in Nature is because a half-evolved and useless organ waiting millions of years to be completed by random mutations would be a liability and hindrance to a species - not exactly a prime candidate for natural selection. In fact, how could species have survived over, supposedly, millions of years while their vital (or necessary) organs were still in the process of evolving!
How, for example, were animals breathing, eating, and reproducing if their respiratory, digestive, and reproductive organs were still incomplete and evolving? How were species fighting off possibly life-threatening germs if their immune system hadn't fully evolved yet?
What if we should find evidence of life on Mars? Wouldn't that prove evolution? No. It wouldn't be proof that such life had evolved from non-living matter by chance natural processes. And even if we did find evidence of life on Mars it would have most likely have come from our very own planet - Earth! In the Earth's past there was powerful volcanic activity which could have easily spewed dirt containing microbes into outer space which eventually could have reached Mars. A Newsweek article of September 21, 1998, p.12 mentions exactly this possibility.
We know from the law of entropy in science that the universe does not have the ability to have sustained itself from all eternity. It requires a beginning. But, we also know from science that natural laws could not have brought the universe into being from nothing. The beginning of the universe, therefore, points to a supernatural origin!
Even the scientific followers of Prigogine, the father of Chaos theory, have admitted that only a very minimal level of order will ever be possible as a result of spontaneous or chance processes.
Those advocating the teaching of intelligent design are not demanding that Darwinian theory no longer be taught. Rather, the advocates of intelligent design want the merits of both theories taught side by side when the issue of origins is covered in science classes and textbooks. This is only fair.
Science cannot prove how life originated since no human observed the origin of life by either chance or design. Observation and detection by the human senses, either directly or indirectly through scientific instruments, is the basis of science and for establishing proof.
The issue is which position has better scientific support. Both sides should have the opportunity to present their case.
What we believe about life's origins does influence our philosophy and value of life as well as our view of ourselves and others. This is no small issue!
Just because the laws of science can explain how life and the universe operate and work doesn't mean there is no Maker. Would it be rational to believe that there's no designer behind airplanes because the laws of science can explain how airplanes operate and work?
Natural laws are adequate to explain how the order in life, the universe, and even a microwave oven operates, but, again, mere undirected natural laws cannot fully explain the origin of such order.
If some astronauts from Earth discovered figures of persons similar to Mt. Rushmore on an uninhabited planet there would be no way to scientifically prove the carved figures originated by design or by chance processes of erosion. Neither position is science, but scientific arguments may be made to support one or the other.
All of this simply means that real science supports faith in God. Science cannot prove that we are here by chance (evolution) or by design (creation). However, the scientific evidence can be used to support one or the other.
It is only fair that evidence supporting intelligent design be presented to students alongside of evolutionary theory, especially in public schools which receive funding from taxpayers who are on both sides of the issue.
Also, no one is being forced to believe in God or adopt a particular religion so there is no true violation of separation of church and state.
There is, of course, much more to be said on this subject. Scientist, creationist, debater, writer, and lecturer, Dr. Walt Brown covers various scientific issues ( i.e. fossils, biological variation and diversity, the origin of life, comparative anatomy and embryology, the issue of vestigial organs, the age of the earth, etc.) at greater depth on his website at http://www.creationscience.com.
Another excellent source of information from highly qualified scientists who are creationists is the Institute for Creation Research (http://www.icr.org) in San Diego, California.
