Proteins are amino acid chains, made up from 20 different amino acids, also referred to as residues, that fold into unique three-dimensional protein structures. The shape in which a protein naturally folds is known as its native state, which is determined by its sequence of amino acids. under 40 residues the term peptide is frequently used. A certain number of residues is necessary to perform a particular biochemical function, and around 40-50 residues appears to be the lower limit for a functional domain size. Protein sizes range from this lower limit to several thousand residues in multi-functional or structural proteins. However, the current estimate for the average protein length is around 300 residues. Very large aggregates can be formed from protein subunits, for example many thousand actin molecules assemble into an actin filament. Large protein complexes with RNA are found in the ribosome particles, which are in fact 'ribozymes'.[/I]
I would have to assume, from your incorrect statements about how much we know about proteins, that your knowledge of biochemistry is even more dated than mine.

I was just scratching the surface of what we know. I regularly read biochem articles in scientific journals. The number of these articles is really staggering. But this really has nothing to do with our discussion.
What you're alluding to is an example of the "Watchmaker analogy" put forth by William Paley in 1803, and which has been debunked repeatedly since. The watchmaker argument basically says you can't have something complex, like a watch, without a watchmaker. For a complete explanation of the problems, and proof against such an argument you should read
Dawkins, Richard, 1986. The Blind Watchmaker: why the evidence of evolution reveals a universe without design. New York: Norton.
