In the beginning the Heavens and the Earth were one.
Fourth Day of Creation
In side the Heavens and the Earth Pangu was born.
Fifth Day of Creation
18,000 years later Pangu woke up than he split the Heavens and the Earth.
Sixth Day of Creation
Pangu continued to do this for another 18,000 years while he did this he and the Heavens and the Earth continued to grow. While he did this a turtle, a qilin, phoenix and a drangon came and helped him with his task.
After all these years had passed Pangu died.
After Pangu died the parasites on his body became humans.
