Every one has a birthday. I can't speak for everyone, but mine have always been accompanied by a cake. That was and is the best part. My question is why do we celebrate with cake? I just took it for granted and never wondered. So i did a little research/ google search and got an answer. The tradition started with the Greeks. They made round cakes to honor the moon goddess Artemis. The reason for the candles is to represent the glow of the moon. The tradition of blowing out the candles and making a wish is after they go out is because the smoke carries the wishes off to the gods. So-hopefully that answers a random question we never think about.
