How Far Can You See at Night?

There was an old man who had witnessed a burglary and appeared in court to identify the guilty party. The prosecutor questioned him, and he identified the defendant as the man who had committed the crime. Now it was the defense attorney’s turn. He asked the man, “Did you see my client commit this burglary?” “Yes,” the man said. “I saw him plainly commit the crime.” The lawyer added, “This happened at night. Are you sure you saw my client commit this crime?” “Yes, I saw him do it,” the man said. The lawyer then said, “You are 80 years old and your eyesight probably is not as good as it used to be. Just how far can you see at night?” The man said, “I can see the moon. How far is that?" (Source - Sermon Central)
