How was mankind created? In Greek tales, it was Prometheus who created mankind. In the ancient Egypt, man appeared on the Earth at the calling of Gods. Jewish tales say Jesus created man. In Chinese fairy tales, it's a woman-bodied dragon-tailed goddess called Nu Wa who made human beings.

After Pan Gu split the sky and earth, Nu Wa was there. She loved everything there. There were birds and beasts, fish and insects already, but on the whole it still appeared lifeless to the Goddess. One day, the lonely goddess saw her own beautiful shadow in the waters of the Yellow river, and she decided to create some company. With her dexterous hands, she turned the yellow mud in the Yellow river bed into little figures in the shape of herself; only she made legs for them instead of tails. She blew a breath into them, and these little figures immediately became alive. And they walk with their back upward and speak intelligently. Nu Wa called them human beings. The goddess also put male and female elements to them and there come men and women.

Nu Wa was happy to see them and wanted to make as many human beings as possible so they could live on each corner of the earth. However, she was too tired so she came up with an idea to stir the mud on to bottom of the riverbed with a rope and throw the rope in the air. The little mud dots became human beings too.  Thus, man was seen everywhere in the world.

Since humans would eventually die, to continue the generation of mankind, Nu Wa made men and women couples. This way they were able to create their own children. That is the explanation of the existence of mankind.
