The fact that we do not understand or are able to explain it means that the gradual evolution of the eye is a matter of faith with you. It is not science. Therefore you have no call to insult those who do not believe as you do and call them names. In addition, that complex systems - and that includes the eye could have evolved is totally unreasonable and that is why there is not a single scientifically legitimate explanation by any evolutionist of the gradual development of any system or major organ of which there are dozens if not hundreds in human beings alone.
