Each of lthe puranas has a different story regarding the birth of Ganesha. In some he is the maanasika putra (mind born son )of Shiva. In others he is the creation of Parvati. In still others he is the son of Shiva and Parvati.
All these are stories from the various Puranas where, firstly , Ganesha appears as the Son of Shiva or Parvati or both and is given powers as the lord of the Ganas by Shiva, and Secondly, acquires an elephant head which replaces his original human head.
The two Upa Puranas, the Ganesha Purana and Mudgala Purana on the other hand treat Ganapati as the Great God himself, to whom even the Trinity pay obeisance and ask for his help to save the world from evil.There are 4 yugas or ages the Krita, Treta, Dwapaara and Kali Yuga. According to the Ganesha Purana , Ganesha incarnated in each yuga or age in a different form for a particular purpose.
