Well--actually, if I were imbarking on an ID research project, it would be to detect apparent design without the possibility of implementation. Such as by searching for God's copyright notice in the junk DNA. This bars the usual, and effective, dismissal of ID that apparent design could have resulted from natural forces.
... uhmm, and in what language should that copyright notice have been written in?
Clearly the request is totally unreasonable. However, what intelligent design tries to do is show that DNA has to be a result of intelligence and try to find something which is universally understood to be the product of intelligence. This is for example what we are trying to do with the Seti program to distinguish a message in an unknown language from random noise.
This evidence of intelligence has been found already within living things. Letters are a sign of intelligence as are any kind of symbols from mathematical ones to other symbols used in many different fields. The ability to represent one thing by another and have it understood for what it represents is a sign of intelligence in both those who 'write' the symbols and those who 'read' the symbols. Such a relationship is the one found in DNA and RNA. DNA writes symbols which have no legitimate significance, these are the three letter codons which RNA reads and interprets as the 20 amino acids from which proteins are formed.
