*Such ordered structures usually have the lowest energy, so will form
spontaneously at low enough temperatures.
*And the information of the crystals is already present in their building blocks; for example, directional forces between atoms.
But proteins and DNA, the most important large molecules of life, are not ordered (in the sense of repetitive), but have high specified complexity.
Without specification external to the system, i.e., the programmed machinery of living things or the intelligent direction of an organic chemist, there is no natural tendency to form such complex specified arrangements at all.
When their building blocks are combined (and even this requires special conditions), a random sequence is the result. The difference between a crystal and DNA is like the difference between a book containing nothing but ABCD repeated and a book of Shakespeare. However, this doesn’t stop many evolutionists (ignorant of Orgel’s distinction) claiming that crystals prove that specified complexity can arise naturally—they merely prove that order can arise naturally, which no creationist contests."
