Carbon is formed in the cores of certain stars after lighter elements have been formed. The carbon on earth came from older stars that exploded to release their carbon.
On Earth, carbon is found as carbonate rocks, and dissolved in seawater as carbonic acid, and in the air as carbon dioxide. Plants and animals contain a small fraction of the Earth's total carbon.
