And in case I didn't convince you I would like to mention a boy that lost his eyes to cancer when he was young. YouTube - ‪Blind Kid uses Echolocation to "See"‬‏.
When he got older he could see. He does it with echolocation. He sees with sound. Now what is different about him that makes him have that ability and not most other blind people? When he was little, after he lost his eyes he told his mom that he couldn't see. His mother told him that he CAN still see, he can see with his ears, and that he can see with his hands. His mother encouraged him to believe that he could see. And so he did. You can just watch the videos on him.
