False allegations of child sexual abuse are when someone says that somebody else abused them even though it isn't true. It's really serious when someone makes a false allegation, because it can take away a person's freedom and damage their reputation and relationships. It can also lead to a miscarriage of justice and innocent people can get sent to jail. False allegations can be made for different reasons, like trying to get attention or revenge. It's very important for adults to take all allegations seriously and investigate them, but also to make sure that the person accused is treated fairly.
