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? As we have seen all biological variation or evolution is limited to within plant and animal kinds.

Another reason for why macro-evolution 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?

Scientist and creationist Dr. Walt Brown, in his fantastic book "In The Beginning", makes this point by saying, "All species appear fully developed, not partially developed. They show design. There are no examples of half-developed feathers, eyes, skin, tubes (arteries, veins, intestines, etc.), or any of thousands of other vital organs. Tubes that are not 100% complete are a liability; so are partially developed organs and some body parts. For example, if a leg of a reptile were to evolve into a wing of a bird, it would become a bad leg long before it became a good wing."

Usually what is meant by the term "biological kind" is a natural species but this may not always be the case. The key to keep in mind here is that in order for evolution in nature to occur from one biological "kind" to another biological "kind" entirely new genes would have to be generated and not just merely modifications and/or recombination of already existing genes. If, for example, offspring are produced which cannot be crossed back with the original stock then there is, indeed, a new species but if no new genes or traits developed then there is no macro-evolution (variation across biological kinds) and the two distinct species would continue to belong to the same "kind".

Science cannot prove we're here by creation, but neither can science prove we're here by chance or macro-evolution. No one has observed either. They are both accepted on faith. The issue is which faith, Darwinian macro-evolutionary theory or creation, has better scientific support.

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.

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 mere undirected natural laws can never fully explain the origin of such order.

Of course, once there is a complete and living cell then the genetic program and biological mechanisms exist to direct and organize molecules to form into more cells. The question is how did life come into being when there was no directing mechanism in Nature. An excellent article to read by scientist and biochemist Dr. Duane T. Gish is "A Few Reasons An Evolutionary Origin of Life Is Impossible".

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, so-called transitional links, 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.

On his website, Dr. Brown even discusses the possibility of any remains of life on Mars as having originated from the Earth due to great geological disturbances in the Earth's past which easily could have spewed thousands of tons of rock and dirt containing microbes into space. In fact, A Newsweek article of September 21, 1998, p.12 mentions exactly this possibility.
