There is much ambiguity using this term coming from creationists and intelligent design proponents. I believe the ambiguity of this particular term causes a bit of confusion as a result, because it doesn’t fully display the meaning when used in general.
Complexity is a term generally used two things which are unique arrangements and specified arrangements. The likes of President-Elect Obama in describing his opposition for intelligent design said that saying life is just too complex, didn’t fit science.
Others have also jumped on the ambiguity of using the term, “complexity” when describing science. PZ Meyers a militant atheist who spends much of his blog time fighting Christianity and religion in general states…
“The lesson of Darwin is that unguided natural processes have the ability to generate complex functionality, so it takes more than just showing complexity and function to demonstrate purpose. Creationists don’t understand that at all, so they keep whining “it’s complex.”
It’s more than merely “complex.” Michael Behe wasn’t the first to use irreducible complexity, one can go back as far as 1968 Professor Michael Polanyi FRS who wrote an article called “Life’s irreducible structure.” In the article, Polany argued that all living organisms have a machine-like structure in them that cannot be reduced to the physics and chemistry of the molecules of which they consist.
We do find complexity in nature that is non-living material as well. For example, ice crystals are very complex when water freezes. However, ice crystals are unable to catalyze the formation of other ice crystals. This reason for this is because chemical reactions only go so far till they reach equilibrium.
As stated in a previous post, RNA in a controlled setting, can replicate itself with the help of biologists. It’s a very complex procedure. While RNA might be able to replicate itself with a duplicate of itself in a lab, it cannot do anything else. Scientists have had admitted, that’s as far as the discovery goes. So it doesn’t really have a practical application for producing life.
Living cells need an operating system, genetic programming, and a translator which can not only encrypt the code but needs a translator which can decrypt the code as well. Specified information is the key to life not just complex information.
Evolutionists contend this simply happened because of the time factor. It’s quite a leap of faith because the theory has no hypothesis for a mechanism that is testable. Information as has been observed like human language, computer software, machines, all have a pattern of being purposefully designed. DNA’s language was purposefully designed.
Chaperonins these highly specialized proteins shelter certain other proteins from water which gives them time to fold properly. Chaperonins have precise expansion, flexible gateways, a timed sequence of chemical events, and other capacities.
So using the term, “complexity” I believe can have too much of a broad meaning. It’s not just complex like stones being blown around on the surface of Mars that is complex or a snowflake, but specified complexity like Chaperonins, computer software, DNA, human languages, and so on.
Nature demostrates the all wise and all powerful Creator who is God (not intelligent agents) as some others would like to speculate.
