What If eye sight did not exist?

What would the world be like If all of humanity had never been able to see, never experienced eye sight and always been born blind...?

Would there be fashion designers? Maybe they'd be called texture designers... Would we even need to wear clothes half the time... How would we get around could we drive? Would the main cause of death be people walking off cliffs?

Radio would be more popular cause TV would not exist. Would people be judged on their voices and not their appearances...

What would happen if then one person was born with eye sight, how would this person explain or describe what seeing is to the rest of the world, when the word seeing would not even exist! How would they describe color when the word color does not exist or the sun and moon and stars...

Would this person be considered crazy? What if there is something like that now and we cant comprehend it because we don't have the words for it....

Maybe I should go to sleep.........
