What is GOD? Why I'm obsessed with this question?

WHAT IS GOD?

Probably............NO, not probably but certainly; one of the most difficult question mankind has ever encountered for centuries; till yet and would still want to answer for time to come. Over the time a lot of people have tried to answer it in their own ways. I'm sure that different ways of thinking can answer it differently. there would be thousands of answers theologically, philosophically, scientifically, rationally, experientially and from perspective of faith and belief. In fact there could be different answers on existence of God from people following the same God. For me there are two kinds of Gods. Personal God and collective God. It flows the same way as personal good and common good. 

First I want to answer what is collective God or the God that we believe in as as society. No matter what religion it is, the idea of collective God organizes us as a society. This God is so powerful that it unites infinite number of people for generations and still remain so farther away....... to be just believed in. I definitely want to know what is this God.

But why do I even bother talking about God? If I don't believe in God then what is point in thinking about it. 

Well I need to talk about it; because God, wherever he is and in whatever form, is controlling my life. As a child I was asked to bow before its image. A little older and I was still bowing before him and calling him in times of crisis. In fact for a long time I kept asking him for wisdom, knowledge and power. By the time I started forming opinions about all things under the Sun; I felt sceptical and even confused about God's existence. The long sown and cultivated beliefs were so strong that even if I wanted to refute its existence, somewhere within me I could not muster enough courage to do so. God has become such an integral part of my own existence that even if I want to stay away from thinking about it, it just barges right in my thoughts without my cognizance. Be it family or society - which define me are all surrounded by the world of God. When my son asks me how a child comes in this world or who put Earth and Sun in the space, I inadvertently tell him its God, to avoid elaborating complex biology at this tender age or to satisfy his curiosity because I don't know the answer myself. Probably I'm preparing another "Me" in my son who would struggle with the same question "What is God?". As a rational, I do not want my son to stand exactly there where I'm today. I want him to have an answer, if not then at least be able to answer it more confidently. Why just him, I don't want anybody to fumble with this question. After-all as creature of nature; we must evolve. We must have our answers. 

When first humans decided there is a God, they chose to believe in its existence. As their successor its my full right and imperative too to take the idea further. Civilizations have formed, progressed and destroyed on this idea. Most of all - I WANT to know what is this God.

The reasons iterated so far, are the reasons I will give to anyone who would ask me why I am so possessed by this question. Personally I know I can not give any reasons to myself. The only reason I want to answer this question is because it just doesn't leave my mind. Perhaps answering it might take it away from me.
