When someone dies, we use things called symbols to remember them and show that we are sad they are gone. One symbol that many people use is a picture of a skull. This is a picture of the bones in a person's head that helps us remember that after someone dies, their body becomes bones.
Another symbol that people use is a picture of a black bird, like a crow or a raven. This is because in many stories and cultures, birds like these are said to represent death.
In some cultures, people use candles or flowers to remember someone who has died. They light the candles to show that they are thinking of the person, and they put flowers near the person's picture or on their grave as a way to make it look nicer and show that they care.
Overall, symbols of death are things that people use to remember someone who has died and show that they are sad they are gone. They can be pictures of skulls, black birds, candles, or flowers, but the most important thing is that they help us remember the person and show that they will always be in our hearts.
