Today, many people believe that if a person can blow out all the candles on a birthday cake in one breath, he or she will be able to make a wish that will come true. This custom comes from an ancient belief: people believe that the smoke coming out of the fire is a symbol of God, and they usually pray to the smoke, hoping that the deep will mention their heart.
Blowing out candles is a custom to cheer up birthdays that originated in ancient Greece. Worshippers of the ancient Greek moon goddess Artemis celebrated the moon goddess's birthday by placing a cake with candles on the altar. As a result, ancient Greece put burning candles on children's birthday cakes as well and added candle blowing. They believed that burning candles had hidden magical powers, and that if a child made a wish and blew out all the candles in one breath, he or she would get what he or she wanted.
