Amino Acids and Protein - What are the odds?

Everyone who ever took a biology class knows what an amino acid is - one of the 'building blocks' of the body, the main constituents of protein, etc. Evolutionists have many theories as to how they  have been formed - some say they could have formed in the primordial soup millions of years ago, as the Miller-Urey experiment seems to have proven; others say they could have been "imported" from meteorites that crashed into the earth, but the fact is that they got here somehow, and now they need to find out how they did.

Proteins are made up of large numbers of amino acids, with ribonuclease (one of the simplest proteins) containing 124 of them. The real reasons that we have been unable to replicate proteins (which would be extremely useful, medically speaking) are: 1. We have been unable to create all of the amino acids necessary for life, and 2. It is very difficult to get all the amino acids into the right order. A diagram is shown below:



As we can see from the picture (if you bothered to look carefully at it),there are seventeen different types of amino acids that go into one strand of ribonuclease, and there are a total 124 amino acids in one strand. Therefore, we can deduce that the odds of one strand of ribonuclease forming (Under the assumption that we have the right number and types of amino acids in a contained environment) are exactly 17^124, which works out to almost double the estimated number of atoms in the known universe! Clearly, this provides quite conclusive evidence against the odds of protein forming naturally. However, given enough time, anything is said to be possible; so this argument can also be overcome.
