What are some real-life mysteries?

My six-year old daughter demands to be told of the world's real mysteries! I've exhausted those I know from the top of my head, like the Mary Celeste, the Antikythera mechanism and those vent channels in the pyramids. I'd like your help, because I'd like to stay fact-based, and Google feeds me an endless supply of conspiracies, UFOs and paranormal phenomena. Solved mysteries are also good, as we can speculate and then "cheat" and look at the answer.
