The National Archives and Records Administration, or NARA for short, is a big building that collects and saves important papers and things from the United States government. Think of it like your toy box, but instead of toys, it has really important things like letters from presidents, old maps, and even the Constitution!
People who work at NARA are like the librarians who help you find a book in the library. Only instead of looking for books, they help people find important government papers they might need, like a person's birth certificate or proof of citizenship.
Sometimes, people even need to find information to help solve a problem, like a law case, so they go to NARA to find old legal documents that can help them.
NARA keeps all of these important papers and things very safe so that they don't get lost or damaged. Just like when you put your toys on a shelf so they don't get broken, NARA puts really important things like the Declaration of Independence in special containers with special chemicals to help them last a really long time.
So, the National Archives and Records Administration is like a big toy box, but for really important things that help people learn about and understand the history of the United States.
