To claim that life evolved is to demand a miracle. The simplest conceivable form of single-celled life should have at least 600 different protein molecules. The mathematical probability that even one typical protein could form by chance arrangements of amino acid sequences is essentially zeroa—far less than 1 in 10450. To appreciate the magnitude of 10450, realize that the visible universe is about 1028 inches in diameter.
From another perspective, suppose we packed the entire visible universe with a “simple” form of life, such as bacteria. Next, suppose we broke all their chemical bonds, mixed all their atoms, then let them form new links. If this were repeated a billion times a second for 20-billion years under the most favorable temperature and pressure conditions throughout the visible universe, would even one bacterium of any type reemerge? The chancesb are much less than one in 1099,999,999,873 . Your chances of randomly drawing one preselected atom out of a universe packed with atoms are about one chance in 10112—much better.
