Okay kiddo, so you know how there are different types of Christian churches, like Catholic and Baptist? The Coptic Orthodox Church is another type.
But what makes it special is that it actually originated in Egypt a long time ago, around the same time that Jesus was alive. The word "Coptic" means "Egyptian" in a language called Coptic.
Now, people from Egypt who practice Coptic Orthodox beliefs eventually moved to North America and started their own churches here. This is why we now have Coptic Orthodox Churches in North America.
These churches have their own traditions and customs, like special prayers and music that involve lots of singing and chanting. They also have their own priests who lead the services and help the people with their spiritual needs.
So basically, the Coptic Orthodox Church in North America is a community of people who practice a certain type of Christianity that comes from Egypt, and they have their own special churches and ways of worshiping.
