A symbol is anything that conveys information or stands for an object or idea.
Symbols are a necessary part of the human experience.
Whether in the form of illustrations, letter symbols, gestures, or spoken words, symbols are the basis for almost all communication. Symbols play an important part of our understanding and learning about human history many years ago. Just as we need symbols today to communicate, the ancient people living on the earth needed symbols to communicate also. Some ancient societies, such as the Egyptians, used letter symbols from their own alphabet to communicate. Individuals, nations, and other organizations use symbols to represent data, ideas, and beliefs.
