The structural design of the eye totally disproves evolution and makes a complete monkey out of it.
For the eye to be fully functional, it had to have been fully created at once, and not evolved. According to the concept of the survival of the fittest, if the eye were to be evolving and not functional until fully evolved, then while the evolving organism was virtually blind until that time, it could not have survived. It would not see where it was going and would have died through accident or falling into water and drowned. It would not be able to see to find food, so it would starve.
Of course, I am not expecting devout evolutionists to believe this, and will always find some twaddle to give some ineffective answer to it as they will with any anomaly in the theory such as the total absence of intermediary organisms to show the evolution of more simple organisms to those of different plant, animal, fish species, and human beings.
