Well, Jack the Ripper is a very scary man who lived a long time ago in England. He was a bad man who hurt and killed women. It was a very sad time when he did these things.
But even though Jack the Ripper was a real person, some people like to write stories about him that are made up. These stories are called fiction.
In these stories, Jack the Ripper might not be exactly like the real Jack the Ripper. Sometimes he might even be a monster or a ghost! But people still like to read these stories because they are very exciting and scary.
Some people even pretend to be Jack the Ripper in movies and TV shows! But don't worry, it's all made up and not real.
Even though Jack the Ripper did bad things a long time ago, it's important to remember that it was wrong and we should always be kind and respectful to others.
