Then let's test your theory, shall we?
Take a jackhammer, encase it in a huge block of ice, turn it on and let it run awhile, then turn it off and see if it -- by coincidence -- hammered out a cavity that, when filled with plastic (or some other pliable material), would solidify and, after the ice melts, there stands a statue in your image and likeness.
(Or the image and likeness of Joe down the street, or Jorge, or anyone.)
In fact, do it 10[sup]50[/sup] times or more -- I'll wait.
Let's rework this experiment of your to more closely resemble how the evolutionary process works shall we?
The selection pressure at work here is selecting towards sculptures that look like humans, as they have a better opportunity to reproduce. Also, to simplefy the process we'll assume that only the one closest to the selection pressures qualifications gets to reproduce.
Alright, so we start with say... 1,000,000 big blocks of marble, ready for sculpting. These represent imaginary species A.
Now we take 1,000,000 sculptors. These represent the proteins replicating the DNA during gametogenesis.
Now, each of them takes their chisel and chisels off a piece of the marble. This represents a small transcription error, or mutation if you will.
All of these chiseled blocks now go to a panel of adjudicators, called mother nature. They judge the one that most looks like a person and pick it to be the template for 1,000,000 more sculptures. This represents natural selection.
Now, each of these 1,000,000 sculptures undergoes the same process, chisel, adjudicate, best gets to be the template for 1,000,000 more.
Now say it takes a day to complete each new generation. That's 365 steps closer to the selection pressure's ideal form that we started with. Now multiply by a billion years. That's 365,000,000,000 generations. 365,000,000,000 selected chisels to make the sculpture look more like a human. That's 3.65*10^17 individual sculptures. (Or Jillion and Jillions as you would say). What are we left with? A sculpture that is perfect down to the individual hair on your head. Even Michaelangelo didn't use 365,000,000,000 individual chips of his chisel to form his famous 'David'.
