Language is not Code
omG .... mama told me not to argue w/ idiots < I'll take her advice
CODE IS DEFINED as communication between an encoder ( a writer or speaker ) and a decoder ( a reader or listener ) using agreed upon symbols
If I wrote on a wall-board .. "Oh lordie is a fat ole dunderhead" in Chinese .... would lordie understand what I wrote ?? ... probably not, no agreed symbols .... sorry mom
btw Oh lord Dave, .. name any code (ie blueprints / music / language / recipe etc) which came about via non-intelligence
............... oops !! and then there was man
And yet, if you wrote it in Chinese, it would still be language.
Code require language to exist, otherwise it has no information to pass on. For example:
Afterthought snore cheer carpenter wakeful rock mend support slow magic exciting ultra.
By your definition this is code yet, decoding it gives you nothing even though it's an agreed upon set of symbols by an encoder and decoder.
A bee's dance is also code and language. So there ya go, that's one. Bee dancing.
DNA is code without language. It's interacts with protein chains based on the laws of biochemistry (which is based on physics) to perform tasks.
However, the problem with finding an example of code not made by intelligence is that you assume God made everything. So thus, there is nothing in your view of the universe that can possibly be made by someone other than an intelligent being. Even if we look at say... ice cores, which have information about the early times of the world in them (which scientists must decode using the agreed upon symbols of physics), you can just say "God did it, so not done by non-intelligence".
