Given the assumptions above we would expect very large numbers of amino acids to be produced every second. But when we examine the probability of a simple protein coming about by chance the numbers become staggering. The age of the universe is many orders of magnitude too small to allow us to expect a chance formation of a protein . And remember, we are assuming that all favorable combinations last until the protein is formed. They tend to break down .
Energy is dissipated.
We cannot expect order to increase by chance. The universal experience of scientists to this effect is formulated in the second law of thermodynamics . And this probability, infinitesimal as it seems, is large compared to the probability of getting a simple protein. It is inconceivable. And remember, millions of proteins would be needed for the next step toward life.
