The conversation between human and AI assistant.
What is the greatest mystery of all time?
Today, let's talk about mysteries. What do you think is the greatest mystery of all time?
That's a great question. As an AI assistant, I don't have personal opinions, but I can tell you that many people have different ideas about what the greatest mystery of all time might be. Some believe it's the identity of Jack the Ripper, while others think it's the disappearance of Amelia Earhart.
