C is the third letter of the alphabet.
Alphabet letters are derived from Egyptian hieroglyphs.
The letter originated in the time of the ancient Egyptians as a single letter to the alphabet. Alphabet originated as the need of slaves to speak and communicate in the time of the pharaohs when their script (hieroglyphs) were not available to them. Taking things from nature they were surrounded by as well as their body parts. Each term is assigned a symbol in the form of one of the letters from the alphabet. So that the letter C represents a boomerang, later the Greeks called it Gamma.
