"Evolutionist Robert Jastrow once wrote:
The eye is a marvelous instrument, resembling a telescope of the highest quality, with a lens, an adjustable focus, a variable diaphragm for controlling the amount of light, and optical corrections for spherical and chromatic aberration.
The eye appears to have been designed; no designer of telescopes could have done better. How could this marvelous instrument have evolved by chance, through a succession of random events? (1981, pp. 96-97, emp. added).
How indeed? Though Dr. Jastrow argued that “the fact of evolution is not in doubt,” he confessed that “…there seems to be no direct proof that evolution can work these miracles.…
It is hard to accept the evolution of the eye as a product of chance” (1981, pp. 101,97,98, emp. added). Considering the extreme complexity of the eye, it is easy to understand why Jastrow would make such a comment. In his book,
Does God Believe in Atheists?, John Blanchard described just how complex the eye really is.
The human eye is a truly amazing phenomenon. Although accounting for just one fourth-thousandth of an adult’s weight, it is the medium which processes some 80% of the information received by its owner from the outside world. The tiny retina contains about 130 million rod-shaped cells, which detect light intensity and transmit impulses to the visual cortex of the brain by means of some one million nerve fibres, while nearly six million cone-shaped cells do the same job, but respond specifically to colour variation. The eyes can handle 500,00 messages simultaneously, and are kept clear by ducts producing just the right amount of fluid with which the lids clean both eyes simultaneously in one five-thousandth of a second (2000, p. 313).
Statements like this proves that the eye was so well designed, and so complicated, that it could not have happened by accident, as evolution teaches."
