Okay kiddo, have you ever watched a movie? I want to tell you about a movie called "Day One". This movie was made in 1989 which means it is really, really old.
The movie "Day One" is about a man named J. Robert Oppenheimer. Oppenheimer was a scientist who helped create a very powerful bomb called the atomic bomb. The atomic bomb was used during World War II to help the United States of America win the war.
The movie starts with Oppenheimer waiting for a big decision on whether or not his scientific project was going to be approved. The project was to build a very dangerous weapon, and many people were worried about its potential consequences.
Oppenheimer gets the approval to move forward with the project and forms a team of scientists to help him create the atomic bomb. They work hard to build and test the bomb, but as they go through the process, they begin to realize the devastating impact that their project could have on humanity.
In the end, they decide to test the bomb in a remote desert area in New Mexico. The explosion is massive and breathtaking, but Oppenheimer's team can't ignore the fact that this weapon could cause unimaginable destruction.
The movie ends with Oppenheimer feeling remorse for what his creation could bring, and the final scene is him quoting from the Hindu scripture the Bhagavad Gita: "I am become death, the destroyer of worlds."
So that's the story of "Day One" – a movie about a scientist who helps create a weapon that could potentially destroy the world. It's a reminder of the importance of responsibility and ethics when dealing with powerful technologies.
