Hello Aniyyah
Countries around the world have their own names,legends and traditions about Santa Claus.
It is believed that the first Santa Claus was Saint Nicholas. Saint Nicholas was a monk.
The Santa Claus that we recognize in North America is said to live at the North Pole. According to some North American sources, his original name was Kris Kringle before he changed his name to Santa Claus. Kris Kringle was a toymaker.
Does Santa Claus exist?... No one truly knows since no one has actually seen him. However, as long as we believe and as long as there is kindness, love, sharing and giving from the heart, the spirit of Santa Claus will continue to exist and millions of people will experience the magic of Christmas morning.
