Some people believe that years later, people would one day travel in time. Everyone makes mistakes, some are small, some are big. I would like to travel back in time and change the mistakes that I did. Though is it really a good thing to travel back into time and change history. No, it is not such a good idea because, One, Changing things back in time might change things right now. Second, Learning from mistakes could help people learn. Changing history might cause lots of troubles, too.
One of the reasons why people should not time travel and go back into time is because changing the events in history might affect things right now. In the story A Sound of Thunder, the main character went back in time through a time machine. While in the time where there are still dinosaurs, the main character accidentally stepped on a butterfly, and killed it. When the main character came back his time, he found out the words that people used changed. This is a example of changing something in the pass and it affected things present. Also going back in time and changing events could cause other troubles like changing other people’s lives or even killing them. So changing things in the past is not such a good idea.
The second reason why people should not change history is that people learn from their mistakes. Everyone would make some mistakes in their life, some people would want to change it. Though after making a mistake, people would change and try to do the right thing. If people changed the mistake, they won’t learn from it and there might be the same mistakes that are going to happen. Also, if people are allowed to change the history, they would think it is fine to make mistakes. After making the mistakes, they could go back and fix it any ways. This is not a good way to think.
Changing history might change lots of mistakes, but there might be other mistakes that are worse then the one that is changed. Also changing the events in the past might cause troubles right now. So going on a time machine and changing events in the past might not be such a good idea. No one knows what would happen.
