As usual Khandro resorts to insults when he has nothing worth saying.
Yes, the path to developing eyes is not particularly complex. This is why eyes appeared early and have independently evolved many times in nature.
A complex organ does not simply appear fully formed but evolves in steps. The only requirement is that any intermediate stage of the evolution must be sufficiently viable to reproduce and thrive.
It begins with the development of a light sensitive chemical in a very early ancestor. Such chemicals are present in the cytoplasm of single cellular organisms and even form into clumps. The ability to sense light affords an advantage.
Similar clumps can obviously be reproduced on a larger scale in a multicellular organism. Those area are afforded a stronger directional sensitivity be dishing inwards. The small steps continue through a ball with a hole and a lens, then colour.
It is pretty simple really. There is no need for a creator. Nature intrinsically has the capability for life and so in a universe on the scale of ours it is pretty much a certainty to happen somewhere. It happened here at least.
