Ok kiddo, have you heard of the Bible? It's a very special book that people use to learn about God and his teachings. The Bible was originally written in different languages a long time ago, and people translated it into many other languages so more people can understand it.
Now, Cornish is a language that's spoken in Cornwall, which is a place in the UK. People there wanted to have a version of the Bible in Cornish so they can learn about God and his teachings in their own language.
But translating the Bible is not easy, especially into a language that's not spoken by a lot of people. That's why a bunch of really smart people came together to make it happen. They spent a lot of time researching and studying the Cornish language, and figuring out the best way to translate the Bible into Cornish so that it makes sense to the people who will read it.
One of the first people to translate the Bible into Cornish was a guy named William Gwavas. He did it back in the 1600s, but his version is very old-fashioned and hard to understand. That's why more people have been working on newer versions that are easier to read and understand.
So, the Bible has been translated into Cornish so that people in Cornwall can read and learn about God's teachings in their own language. Pretty cool, right?
