Although the idea of life forming by random chance isn’t taken seriously right now among scientists, the idea is still very much alive at the popular level. Many college students, for example, speculate that if you let amino acids randomly interact over millions of years, like is somehow going to emerge. The problems with that theory became apparent to me pretty quickly. Imagine trying to make even a simple book by throwing Scrabble letters onto the floor. Or imagine closing your eyes and picking Scrabble letters out of a bag. Are you going to produce ‘Hamlet in anything like the time of the known universe? According to George Sim Johnson:
“Human DNA contains more organized information than the ‘Encyclopedia Britannica.’ If the full text of the encyclopedia were to arrive in computer code from outer space, most people would regard this as proof of the existence of extraterrestrial intelligence. But when seen in nature, it is explained as the working of random forces.” Even a simple protein molecule is so rich in information that the entire history of the universe since the Big Bang wouldn't give you the time you would need to generate that molecule by chance. Even if the first molecule had been much simpler than those today, there's a minimum structure that protein has to have for it to function. You don't get that structure in a protein unless you have at least seventy-five amino acids or so.
First, you need the right bonds between the amino acids. Second, amino acids come in right-handed and left-handed versions, and you have to get the left-handed ones. Third, the amino acids must link up in a specified sequence, like letters in a sentence. Run the odds of these things falling into place on their own and you find out that the probabilities in forming a rather short functional protein at random would be one chance in a hundred trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion. That is a ten with one-hundred and twenty-five zeros after it! And that would only be one protein molecule; a fairly simple cell would need between three-hundred and five-hundred protein molecules. When you look at those odds and evidence, you can see why, since the 1960's, scientist have abandoned the idea that chance played any significant role in the origin of DNA or proteins.
