Patterns occur naturally – no help required from a ‘designer’. Many patterns occur in nature without the help of a designer – snowflakes, tornados, hurricanes, sand dunes, stalactites, rivers and ocean waves. These patterns are the natural result of what scientists categorize as chaos and fractals. These things are well-understood and we experience them every day.
Codes, however, do not occur without a designer.
Examples of symbolic codes include music, blueprints, languages like English and Chinese, computer programs, and yes, DNA. The essential distinction is the difference between a pattern and a code. Chaos can produce patterns, but it has never been shown to produce codes or symbols. Codes and symbols store information, which is not a property of matter and energy alone. Information itself is a separate entity on par with matter and energy.
Proof that DNA was designed by a mind: (1) DNA is not merely a molecule with a pattern; it is a code, a language, and an information storage mechanism. (2) All codes we know the origin of are created by a conscious mind. (3) Therefore DNA was designed by a mind, and language and information are proof of the action of a Superintelligence.
We can explore five possible conclusions:
1) Humans designed DNA
2) Aliens designed DNA
3) DNA occurred randomly and spontaneously
4) There must be some undiscovered law of physics that creates information
5) DNA was Designed by a Superintelligence, i.e. God.
(1) requires time travel or infinite generations of humans. (2) could well be true but only pushes the question back in time. (3) may be a remote possibility, but it’s not a scientific explanation in that it doesn’t refer to a systematic, repeatable process. It’s nothing more than an appeal to luck . (4) could be true but no one can form a testable hypothesis until someone observes a naturally occurring code. So the only systematic explanation that remains is (5) a theological one.
To the extent that scientific reasoning can prove anything, DNA is proof of a designer.
