We're all blind though, that's the thing. We, as a species, came from stalking rabbits but nekked in teh forest with sharpened rocks to having robot fighter planes kill our enemies...all done because the blind led the blind.
Ask a question, disagree and go find the truth.
Yes, we are all blind to a degree but some are, obviously, more than others and that little cute example you provided doesnt even properly correlate to the point you were trying to make.
The point is, if you can be rest assured on the origins of species by unfounded assumptions and shoddy guesswork then more power to you
