I would love to hear go to some points in history and listen to some Historical Figures giving a speech , or just talk to them and interact to them , and I ' m gonna mention some if knowing their language is included by default , cause of course many of them are not going to talk in English Caesar Aristotle Jesus Christ Leonardo Da Vinci Prophet Muhammad Albert Einstein Malcolm X Martin Luther King Napoleon , and many more . I would like to go and see some old Civilizations if I was sure that I would be safe like Ancient Greece Ancient China Ancient Egypt The Roman Empire Ottoman Empire Islamic Spain Abbasid and Umayyad Caliphate Italy during Renaissance , and many more . Some particular events which I would like to witness Building of Pyramids Gladiator fights Spartan wars Building of the Wall of China , and others .
