I see you are wrong here, that seeing is believing? It could be true but not all the time, only some time. There are so many illusions out there that your eyes can deceive you very easily.
All we perceive with our senses, of see and touch are only representations of reality but not reality itself. Hahaha magicians trick your eyes to make things dis-appear but it only appears that way? The thing is still there. Why don't you read this famous book 'Optical Illusions' and you will know what I am talking about!
