12. The origin of life remains a mystery.
Origin of life theorists have struggled simply to account for the origin of pre-biological organic chemicals on the early earth, with little success. So drastic is the evidence against pre-biotic synthesis, that in 1990 the Space Studies Board of the National Research Council recommended that origin of life scientists undertake a "reexamination of biological monomer synthesis under primitive Earthlike environments, as revealed in current models of the early Earth."2 But this is only the beginning of the problem, as leading origin of life theorist Stanley Miller once admitted that "making compounds and making life are two different things."3
When trying to "make" the first life-form, scientists cannot rely upon Darwinian processes. Darwinian evolution requires replication, and prior to the origin of life there was no replication. Origin of life theorist Robert Shapiro explains that an explanation for the first self-replicating molecule "has not yet been described in detail or demonstrated" but "is taken for granted in the philosophy of dialectical materialism."4
Accounting for the origin of a self-replicating molecule would still not explain how modern cells arose. Our DNA code requires an irreducibly complex system requiring the information in DNA, the enzymes that assist DNA's replication and protection, a protective cell membrane, and a complex system of machinery used to transcribe and translate language of DNA into protein. Faced with the complexity of this system, biologist Frank Salisbury lamented in 1971 that "the entire system must come into being as one unit, or it is worthless. There may well be ways out of this dilemma, but I don't see them at the moment."5
In 1995, leading biologists John Maynard Smith and Eors Szathmary explained that accounting for the origin of this system remains "perhaps the most perplexing problem in evolutionary biology" because "the existing translational machinery is at the same time so complex, so universal and so essential that it is hard to see how it could have come into existence or how life could have existed without it."6
Scientists may one day create life in the lab. But they will have done so using intelligent design. The theory that life could have originated via blind natural chemical processes relying upon sheer dumb luck remains unexplained.
