If evolutionists are correct that biological life developed through a process of gradual changes, then it is far more likely that some type of Intelligence Designed life rather than that life developed without any intelligent controls.
Development through gradual change is the process humans use to produce things from automobiles to literary works to computer programs. The original automakers developed a simple vehicle with some type of motor, wheels, chassis, etc. Subsequent engineers modified these various components to produce faster, more efficient and safer vehicles.
Two groups of True Believers control the debate over the origin of life. The Evolutionists believe that life could only have developed from one original cell through a slow process of gradual changes that was not controlled by any type of Intelligent Being. Creationists believe that God created life and the only way God could have created life was to zap each individual species into existence fully developed.
Creationists don't explain why God would go to the trouble of designing life that can develop from a microscopic sized cell to something the size of an elephant or whale and then initially make each one fully developed instead of creating the cells and letting them develop in some nutrient rich medium. A being capable of creating a universe would be capable of creating an environment in which individual cells could develop into fully sized forms.
Nor do they explain where this belief comes from. Genesis says for the various life forms that God commanded the earth to "bring forth" and the earth "brought forth". That does not indicate God created each species separately. It indicates He ordered the earth to produce various classes of life forms such as plants or fish.
Both groups misunderstand the concept of Intelligent Design. The Intelligence wouldn't necessarily be the God of Abraham. The Designer might be inhabitants of a distant planet who put the necessarily biological products in comets and sent them throughout the galaxy. A Designer might have controlled the initial development of biological life and then allowed it to change without control. The Designer probably would not have made the first member of each species fully developed as Creationists believe.
Both Creation and Evolution involve ancient ideas. Charles Darwin didn't invent the idea of one species becoming another, he merely tried to come up with an argument for it. The ancient Tibetan religion went so far as to suggest that humans descended from monkeys. Darwin only suggested that humans and apes have a common ancestor.
The biggest argument for Intelligent Design is the extremely sophisticated characteristics of biological life, especially animal life. Presumably intelligent humans have only recently developed the necessary knowledge to duplicate the ability of the sophisticated audio input output "devices", video input devices, etc. possessed by animals. It seems unlikely such devices could just have happened to develop.
The cell itself can be described as a computer because, like a computer, when it receives an input, it checks its memory for the appropriate instruction and then executes that instruction. Biologists refer to the bases that make up the DNA molecule using four letters, but they can also be represented by "zeros" and "ones" like in a computer. Each link in the DNA molecule consists of one set of bases or the other("0" or "1"). Within a link one member of the set or the other ("0" or "1") is attached to a specific side.
One approach an Intelligent Designer might have been likely to have used would have been to create one cell to serve as a prototype. The Designer could then have added different modifications to the daughter cells of that original cell. A Designer unaffected by time might periodically have changed the design of life forms for various reasons including being bored with the older life forms.
An Intelligent Designer could have developed subsystems like eyes, hearts, etc. by making specific genetic changes, but development of such subsystems through random genetic changes would be mathematically improbable at best.
Evolutionists ignore the fact that an environment capable of producing one cell would almost certainly produce millions of cells that would probably have begun with subtle differences. Such cells could have had the ability to produce different sets of DNA and then "share" DNA when one cell ate another.
Creationists and Evolutionists would have more believable theories if they would switch one of the components of their theories. Creationists should be claiming that God started with a single cell and developed different species from it. Evolutionists should claim that different species developed from separate cells with the necessary DNA to produce animals with hearts, skeletons, etc. as the animal developed.
