Who is god?

This chapter tells you about god. I belong from India and I have seen that numbers of people belong from different religion and follow different gods. I just want to know that anyone have seen god. No one have seen god but they follow god as per their religion.Hindu people belives in gods which live in temple. Muslim people belives in god which lives in darga and parsi people belives in god which lives in church. All are rubbish things. s
