Again from www.creationscience.com Part 1:

8. Complex Molecules and Organs
Many molecules necessary for life, such as DNA, RNA, and proteins, are so incredibly complex that claims they evolved are questionable. Furthermore, those claims lack experimental support.a
There is no reason to believe that mutations or any natural process could ever produce any new organs—especially those as complex as the eye,b the ear, or the brain.c For example, an adult human brain contains over 10 to the 14th (a hundred thousand billion) electrical connections,d more than all the electrical connections in all the electrical appliances in the world. The human heart, a ten-ounce pump that will operate without maintenance or lubrication for about 75 years, is another engineering marvel.e
33. Genetic Information
The genetic information in the DNA of each human cell is roughly equivalent to a library of 4,000 books.a Even if matter and life (perhaps a bacterium) somehow arose, the probability that mutations and natural selection produced this vast amount of information is essentially zero.b It would be analogous to continuing the following procedure until 4,000 books were produced:c
a. Start with a meaningful phrase.
b. Retype it, but make some errors and insert a few letters.
c. See if the new phrase is meaningful.
d. If it is, replace the original phrase with it.
e. Return to step “b.”
To produce just the enzymes in one organism would require more than 10 to the 40,000th trials.d (To understand how large this is, realize that the visible universe has fewer than 10 to the 80th atoms in it.)
Since 1970, evolutionists have referred to large segments of DNA as “junk DNA,” because it supposedly had no purpose and was left over from our evolutionary past. We now know this “junk” explains much of the complexity of organisms. Use of the term “junk DNA” reflected past ignorance.e

34. DNA Production and Repair
DNA cannot function without at least 75 preexisting proteins,a but proteins are produced only at the direction of DNA.b Because each needs the other, a satisfactory explanation for the origin of one must also explain the origin of the other.c The components of these manufacturing systems must have come into existence simultaneously. This implies creation.
When a cell divides, its DNA is copied, sometimes with errors. Each animal and plant has machinery that identifies and corrects most errors;d if it did not, the organism would deteriorate and become extinct. If evolution happened, which evolved first, DNA or its repair mechanism? Each requires the other.
