To my surprise, I have started to see that religious conservatives want to "offer alternatives" to evolution. For some reason, they dislike evolution and when they do that they also show contempt for the science that lead into the development of the theory. What is somewhat encouraging is that, apparently, they have tacitly acknowledged that creationism cannot survive in a well informed world.
Intelligent design is creationism that tries to show itself as science. It is exactly the opposite to science. The word science has a Latin origin that means knowledge. It is knowledge acquired , to describe nature, to improve our living conditions and sometimes to beat our enemies. When Charles Darwin proposed the theory of evolution in his book Origin of Species, he did it based on observations he had made for years. Natural selection is a phenomenon that is seen all the time. Whenever a bacteria develops resistance to an antibiotic, whenever an insect develops resistence to a pesticide or whenever a population of birds changes its color to be more protected from predators we see natural selection. Evolution is just the appearence of new species based on it. Since the species that exist now, are not the same that the ones which existed 5 million years ago, we have to conclude that there has to be a process that leads into the formation of these new species. Natural selection is the strongest candidate. Intelligent design appears in order to contradict evolution, not to describe nature, so it is not science. It is interested, it has an agenda. It implies that a superior (intelligent) being created the complexity of the Universe. It want as to keep gods in our mind in view of the dying creationism.
