How to explain to a 7 year old kid how Google works?
Imagine you have a big library filled with books on different topics. You want to learn about dinosaurs, but you don't know which books have information on them. So, you ask a librarian to help you find the books. The librarian uses an index of all the books in the library and gives you a list of books that have information on dinosaurs. You can then take those books and read about dinosaurs.

Google is like a giant library of information, but instead of books, it has websites. When you search for something on Google, it looks through all the websites on the internet and finds the ones that are most relevant to your search. It does this by using a special algorithm that looks at different things on the website, like the words on the page and how many other websites link to it. Then it gives you a list of websites that are most likely to have the information you're looking for.

So, just like how a librarian helps you find the right books in the library, Google helps you find the right websites on the internet.
Rewrite it a bit with the acknowledgement that Google hides certain results like copyright protected content and (meta-)political content which the government does not approve of.

However, Google also has rules, just like how your school or your parents might have rules. These rules help make sure that you only see websites that are safe and helpful. For example, Google might hide websites that have bad words or show things that are not good for kids to see. Additionally, sometimes Google hides websites that have copyright protected content or (meta-)political content that the government does not approve of. This helps keep everyone safe while using Google. So, just like how a librarian helps you find the right books in the library, Google helps you find the right websites on the internet while also keeping you safe.
