Even if evolutionists could prove that the biological machinery of life arose spontaneously (which they can’t), they can’t even come close to explaining how the genetic code came to be.
The information carried in our DNA is stored as a code and is decoded by biological nano-machinery. A code is meaningless without an INTELLIGENCE bestowing meaning upon what would otherwise be arbitrary arrangements of proteins.
A vastly less complex analogy would be the English alphabet. We have 26 letters that when arranged in certain sequences form words, which when arranged into other sequences form sentences, then paragraphs, etc. There are also spelling conventions and rules of grammar. Yet, absent an intelligent mind assigning meaning to all of the components of written communication and an intelligence establishing rules for decoding written language, our letters and words and sentences would be nothing more than arbitrary meaningless blots of ink on paper. Even if you could somehow prove that the paper and the inkblots arose spontaneously, so what? It is a quantum leap beyond that to prove that the meaning contained in even a simple sentence arose without intelligent design, much less works such as the sonnets of Shakespeare or War and Peace.
Evolutionary theory is therefore foolish. It is impossible for a code to arise by chance since by definition it requires an intelligent mind to assign meaning to it.
That it did not arise by chance does not mean that it did arise immutable. There is no apparent logical reason that evolution cannot be inherent in the design.
