What the poster fails to mention is that Darwin failed to discover an evolutionary pathway used to make the eye.
There's a great deal that Darwin failed to discover, which is fortunate because it left something for future generations of scientists to do.
You could write for pages and pages about what scientists of prior eras failed to discover, and could even go on for pages and pages about what today's scientists have yet to discover. The whole name of the game in science is tackling unsolved problems, and fortunately there are always lots of those. It isn't much of an accomplishment finding things we don't know yet, and it makes little sense to claim that the things we don't know call into question the things we do.
Saying something "could" have developed in a particular manner isnt the same as providing viable, scientific evidence that it has.
This is true.
This is the problem with societies main stream view of evolutionary science. Possibilities and educated guesses get presented as irrefutable fact.
But your Darwin excerpt is not an example of this.
