Well, that's a long story. But the short version is that Christmas began as a celebration of the birth of Jesus Christ, the Christian faith's most important figure. Over time, it evolved into a secular holiday that's celebrated all over the world, regardless of religious beliefs. It's become a time for people to gather with family and friends, exchange gifts, and enjoy festive traditions like decorating trees, lighting candles, and singing carols. For many, it's a time to reflect on the year's events and look forward to the new one.
