To believe. To believe, you need proof? Why? (Please note the question mark at the end of proof, it was not of my will. Like the word "deaf" in my post "Googling". I thought I used a period and the word "mute").
Grasshopper. Because if you had proof, it would be real. Not a belief. By definition you must believe the incomprehendible. Like believe in God. Justice. Good. Truth. You can believe in things like Money, Sex, Pleasure. But they can be False in many ways.
