Papyrus is a really old piece of paper that people used to write on a long time ago, even before the time of computers. Some of these pieces of paper have been found and are really important because they tell us about the people who lived a very long time ago.
Papyrus Amherst 63 is a special papyrus that was found in Egypt. It is really old, about 3,500 years old, and has a lot of writing on it in a language called Egyptian hieratic. The writing tells us about a man named Paneb who was in trouble with the law. He did some bad things and he was brought to court to be punished. The papyrus has evidence like witnesses, the things that Paneb did, and what the judge decided to do about it.
So basically, Papyrus Amherst 63 is like a page from a really old history book that helps us learn about how people used to live and what they did. It tells us about the rules they had and how they were punished for breaking them. It's like finding a time capsule from a really long time ago!
