Footprints

It is really quite silly if you think about it. So often you hear “I can't believe that because I did not see it with my own two eyes!” Do you really need to see it to believe? Do you need “hard evidence” to recognize the existence of a Truth? If your answer is yes then let me direct you to my window. I am absolutely certain that a person walked across my back yard. Did I see them? No. Hear them? No. Have video surveillance? Not that either. Then how can I be so sure? Do you see the freshly fallen snow? The footprints? The Defense rests.
