Professor A.E. Wilder Smith has an interesting discussion of these matters in his book: The scientific alternative to neo-Darwinian evolutionary theory (1987). He points out that the DNA molecule is the carrier for complex genetic information (p.83).
`The base sequences of the genetic code, that is, the order in which adenine, thymine, cytosine and guanine appear in succession to one another, is certainly by no means random... [Furthermore], non-random sequences in the DNA molecule are governed in no uncertain terms by a language convention...`What other conclusion is possible from these facts but that behind such non-random genetic sequences governed by a language convention, intelligence, or at least an intelligent source, must with certainty lie.'
Wilder Smith throws out a challenge to the ETI researchers: if they let their computers loose on the signals emerging from the electron microscopes, there will be no shortage of positive signals! The conclusion is inevitable. In the words of Wilder Smith: `life here on Earth . . . arose as a result of intelligent information having been hybridised with matter.' Here is a message for us, embedded in every living cell, placed there by our Creator.
