Bethlehem is a place in the world where people who believe in a religion called Christianity think is very important. It's a city where Jesus was born a very long time ago, and it's located in a country called Israel, which is in the Middle East. Bethlehem is a really special place because lots of people think of it as the birthplace of Jesus, who they believe is the son of God.
It's also a place where lots of Christian people like to visit, especially around Christmas time, which is when they celebrate the birthday of Jesus. They might go there to see the places where Jesus was born, like a special church that is called the Church of the Nativity, or to try special foods and learn about the history of Bethlehem.
Even though it's a really important place for lots of Christian people, not everyone who lives there believes in the religion. Bethlehem is actually home to lots of different people from different religions and backgrounds, and they all live together in the same city.
