Earth is one planet among the nine planets which is not equal to a single atom in spite of so large size in comparison to big planets and sun. Third strange thing related to earth is the origin of creatures on the earth.
A famous epic describes that the origin of sky is soul. Besides it, water is the source of the origin of earth and medicines and herbs take birth from earth; corn has taken birth from the medicines and man has taken birth from the corn. Hence, earth (corn) is the source of the origin of human being.
