Who create God? Why there is always a confusion, misunderstanding and debates on the topic of God? Why do people want God? Isn't we are the one to make everything possible? We don't have to give our faith and hope to God. Isn't it ? Why God exists in all people mind? 
it was already existing during the stone age era, where people do rituals to ask for a specific phenomena, child birth, rain, catching fish, healing of the sick, etc.
But God existence has yet to be proven by scientist. Faith also gives people hope and religious literature guides people's values and morality.
