The miracle of DNA translation to proteins - How did it evolve? Or did it?

I'm not into Creationism, but Intelligent Design...yes...and one of the reasons why is the astonishingly intricate and evolutionarily baffling machinery of life that translates DNA sequences into proteins:

First, watch these two videos, then see my comments below:

The molecular machinery described in the videos has been found in one form or another in all life on Earth for the last 4 billion years. But how did it arise? The ribosome, which functions like a giant enzyme, is composed of a combination of RNA and protein, and not just protein like other enzymes. Since the ribosome is required for making proteins, how could it have "evolved", if the proteins necessary for it to function successfully (see below) did not already exist?

Especially amazing are the transfer RNAs, or t-RNAs, which carry the amino acids to the ribosomes to be linked into protein chains. There are 20 main amino acids found in proteins, and for each amino acid there is at least one distinct t-RNA specific to it. And then there are the enzymes which attach the correct amino acid to each t-RNA, which are called aminoacyl tRNA synthetases. There is a different one of these synthetases for each t-RNA. How did these "evolve" in the absence of the protein making machinery in the first place?

There is a real chicken-and-egg problem here. It is hard to reach any other conclusion than that there was Someone behind the curtain, setting the stage. This is one argument I use to introduce "rational humanists" (i.e., atheists) to the idea that they might want to expand their thinking on the subject.
