God can and does coexist with many things in life, the theory of Darwinism is not going to deter Truth. One can choose not to accept the theory of evolution that Darwin proposed in his "On the Origin of Species" in 1859 and side with creation or they can attempt to justify scientific inconsistencies in evolution theory by developing some kind of middle-of-the-road hypotheses, such as intelligent design, complexity theory, irreducible reduction, developmental biology or a synthesis of them all.
Creation theory as taught in the Bible, understood by millions as the Holy Word of God, tells us that human beings and life were created within six days. But the Bible also tells us that "one day is as a thousand years in God's sight," so many believe that rather than a literal six-day period, perhaps God caused the earth and the life upon it over a longer period of time which would give some wiggle room to believing that life, as we know it, developed slowly and consequentially.
Evolution suggests a kind of random selection, survival of the fittest, development by adaptation rather than by design. For this reason many religious people feel that Darwin's theory propounds a world with no ultimate purpose or meaning. If the only thing that matters is a cosmic struggle for survival towards biological perfection, where do those who suffer from developmental abnormalities fit in? If there is no ultimate creator, then evolution only answers how we arrived, not why.
Intelligent design by contrast proposes that we can see some kind of intellectual preciseness in the handiwork of existent being. Like the intricate parts of a watch, we can see complexity in the development of the tiny parts of an eye, which Darwin himself says gave him pause for thought. How could such specificity of purpose, coordination with nerve cells and extraordinary connection with the inner workings of the mind develop over time by sheer chance and circumstance? What's more, we all SEE differently dependent upon what our minds determine or interpret. Colors become a mere matter of subjectivity.
Complexity theorists look at life like a giant pool table. When one hits the cue ball, it drives all the other balls around the table, but some times one gets lucky and the right ball drops into the bucket. Sometimes one is not and the black eight-ball goes in. The mere fact that over thousands of years such randomness and chaos should arrive at the perfect world we see now which may actually show some sense of balance and alignment puzzles scientists. Perhaps life was even designed specifically to suit the needs of mankind when we examine gravity, oxygen, photosynthesis and light. Perhaps not when we think about the proliferation of bacteria, pests and mankinds' inhumanity to itself by genicide.
Reduction theorists find life at the lowest common denominator. Like math they like to keep things rounded out and at their most base level. One example of this way of thinking would be the unusual ethics surrounding multiple births by invitro fertilization. As unnatural as the consequence of one mother having 14 children may be, science has now made that possible. If one is going to rely upon mere science to accept propogation of the species, then are we going to let the chips fall where they may? Survival of the species may very well imply that "no man is an island" and raising children does mean responsibility for child rearing "by the village." Should a mother of multiple births be required to reduce progeny for economic, social or psychological reasons? Who is going to be the judge of who lives and who dies?
Developmental biology includes more recent science such as stem-cell research and development. The scientists are creating in an evolutionary way, but unlike Darwin who apparently did not imagine this day would come so soon, the origin of the species is getting a little help. Not by Mother Nature, but by genetic engineers who can create cells with particular purposes by design. The environment of course will always have the last word however. Despite gene-splicing where even vegetables can now contain cells from fish to make them pest resistant and animals are pumped by hormones to increase growth, human beings cannot control the weather or natural disasters. "Acts of God," as defined by the insurance industry, still may have the last word.
