Dawkins in his very glorious book "The God delusion" has spoken about grief and its role in religion and religious ideas. (Reference) I don’t know that if when he was thinking abut this matter has the same thing in his mind that I want to speak about here or not?
As I will show later the idea of a personal God has been shaped just in Mesopotamia and it has been transferred to the entire world because the idea had and still has two very important strong points; it is an imperialistic idea and it has very strong power to separate people from each other.
God makes a division between people: God divides the world into two parts; divine and evil. God divides people into two parts; believers and infidels.
When people are praying they are individually connected to the God; no mediator or adviser or helper is needed and also it is not possible, unless he or she is the man or woman of God; here we are seeing some division between people. The God gets its power from this separation that it produces between people. This separated people, now, can just listen to its voice. In this way he separates people from each other to produce illusions. These hallucinated people are just like schizophrenic and paranoia individuals who think everybody is their enemy. It is a very good and powerful strategy. Now people are prepared to listen to the one who declares he has a very strong relation with this God; prophet.
God is an Imperialist: this God wants to send its message to the entire world. It is not important that it has signed an agreement with a specific tribe, Yahweh, or it is a universal God. It wants to seize the control of the entire world. All the power that the God has has its roots in the mentioned division. How this division has been produced? As I will show it is just because of the weakness of primitive human language and irritant weather situation that was not under the control of the humankind of the beginning era of Sumer, that it has been said to be the dawn of human civilization. I think that the grief of Gilgamesh has been announced to the world by such a loud voice that nobody can resist hearing; the grief of death, the grief of the Primary Flood that has enforced the ancient Sumerians to migrate from their so called heaven and to descent to Mesopotamian hell, the grief of losing the gold ages; nostalgia. This nostalgia that has its roots just in the weakness of the primitive language and an unwanted migration has shaped the human history. It is this grief that is repeating and duplicating itself in the entire history of humanity. This grief has been resulted to produce a God that it is responsible to reproduce this grief. This grief that can make a very big inscrutable separation wall between people is the main root of God's power. This grief has enforced us to be departure as a schizophrenic personals. It divides us from our physical body.
