Lots of evidence. But if a priori you claim that anything explainable by means of purposive intelligent action is also just as easily explain (in principle) by means of physical matter, energy, and some combination of chance and deterministic law, then you are claiming that no argument for the existence of a Creator is even possible. You've simply closed yourself off to it. For the record, The biochemical evidence is overwhelming. The recently published results in the prestigious British journal Nature of the ENCODE project (which studied the functionality of the genome) shows that about 90% of DNA is functional, i.e., is transcribed onto RNA, and therefore has some kind of function within the cell. The researchers claimed that they expect 100% of DNA to be functional. It appears that only a small part of DNA actually codes for amino acids in the process of protein synthesis. The rest of the DNA strand does other stuff, apparently controlling much of the "formatting" (to use a term from desktop publishing) of the coding part. The significance of all this (aside from the fact that scientifically it's interesting in its own right) is that the notion of "junk DNA" — i.e., long, non-coding, NON-FUNCTIONAL, stretches of DNA apparently being preserved "errors" [the DNA equivalent of fossils] of random variation and natural selection over millions of years of genomic evolution — is out the window. None of it is junk. All of it is functional. It's quite funny to read many of the Darwinists backpeddle on this issue now: "Oh, we NEVER used the phrase 'junk DNA' in the first place! That was just the popular press exaggerating things!" Etc. Anyway, the ENCODE results have hammered the final nail in the coffin of junk DNA, an important element of the Darwinian scenario on evolution. Additionally, a company called "Agilent" has successfully used DNA as an actual storage medium for jpeg images and text (they encoded all of Shakespeare's sonnets and some images on a few grains of DNA). The DNA was flown to their sister office in the U.S., which successfully decoded the data and read it off with near 100% fidelity. Sorry, but the ability to use DNA for human data storage proves that the original molecule was already a kind of storage device, making use of a 4-symbol code (i.e., the nucleotide bases making up the rungs of the DNA helix) instead of a 2-symbol code like binary, which is what our man-made computers "understand." Hard-drives don't appear in nature by means of random processes and deterministic forces; they are the results of intention and purpose. Same with DNA, which is nothing but a very small hard-drive -- literally. By the way, the compression of DNA storage is fantastic, even given the rough state of today's technology: according to its inventors, 1 gram of DNA (about 1/3rd of a teaspoon) can easily store 1 petabyte of data. 1 petabyte is 1,000 terabytes. So envision 1,000 1-terabyte hard-drives stacked up in your office, completely filled with data. Then compare that to a teaspoon 1/3rd full of powdery specks of DNA. If the 1,000 hard-drives stacked up in your office couldn't appear by means of a Darwinian process, why would anyone choose to believe the teaspoon full of microscopic biochemical hard-drives were? And again: the only difference between DNA used to store information about JPEG images and text, and DNA actively functioning in your cells is the choice of data: the latter store data on amino acid selection, protein synthesis, and other cellular processes. Au contraire. Reason is a subcategory of faith. That's why Dante, in the "Purgatory", required the character of Virgil (the "shade" of the great Roman poet, who symbolically represented reason, and had acted as the benevolent guide for Dante while he was making his travels and discoveries in the "Inferno") to remain behind, unable to enter heaven with Dante as he made his final voyage in the "Paradiso". Since Virgil was a pre-Christian pagan, he could not have had the requisite faith to enter heaven with Dante and act as a guide. You should read Dante sometime.
