The Acts of the Apostles is part of the New Testament of the Bible. It tells the story of Jesus and his followers after he died. It talks about how Jesus' followers spread his message in different places and how they faced different kinds of troubles. Historians believe that the Acts of the Apostles is generally reliable because it was written by a man named Luke, who was a friend of one of Jesus' disciples. Luke wrote down the stories of what happened with Jesus and his followers after Jesus died. He tried to make sure he got the story as accurate as possible. So even though it was written thousands of years ago, historians trust its accounts of what happened.
