Okay kiddo, the Catholic Church is a big religious group that believes in Jesus and God. They have churches all over the world where people can go and pray and learn about their faith. But Afghanistan is a country where most people follow a different religion called Islam. So, there aren't many Catholic churches there.
In fact, the Catholic Church doesn't have a big presence in Afghanistan at all. Even though there are some Christian people living in the country, it can be dangerous for them to practice their faith openly because most people there don't understand or accept it. So, it's better for them to keep their beliefs to themselves and not draw attention to it.
Overall, while there might be some Catholics in Afghanistan, the Catholic Church doesn't have a big role to play in the country because people mostly practice a different religion there.
