Nobel prize-winning physicist Eugene Wigner has shown that the probability of the existence of a self-duplicating unit is zero. Since the ability to reproduce is one of the fundamental characteristics of all living organisms, Wigner concludes that our present understanding of physics and chemistry does not enable us to explain the phenomenon of life. Herbert Yockey has demonstrated by information theory that even a single informational molecule such as cytochrome c (what to speak of complex organisms) could not have arisen by chance in the estimated lifetime of the earth: "One must conclude that, contrary to the established and current wisdom, a scenario describing the genesis of life on earth by chance and natural causes which can be accepted on the basis of fact and not faith has not yet been written."
