Why Do People Celebrate Birthdays and What Is Their Origin?

People celebrate birthdays because they want to say "Happy you are here!" to someone special on the day they were born.

Imagine your favorite toy, it’s super fun to play with every single day, but once a year, you get to do something extra special with it. That’s like a birthday! People have a party or cake because it's a special day when you came into the world.

Birthdays are like anniversaries of being alive. Every year, you get older by one, just like how your height grows when you wear bigger clothes. People give presents to make the day extra fun, kind of like giving a gift to your favorite toy on its special day.

A long time ago, people didn’t have cakes or parties, but they still knew it was special when someone was born. They made big events with food and songs, just like how you might sing "Happy Birthday" today! Over time, this became a tradition that we all love now.
