It is really weird as we can see now, there are many people who depends on religion heavily in order to carry out their personal life well. EG. Going to church, temple, mosque to seek for forgiveness and prayers, Does acknowledging that something somehow do exist in which we cannot see, touch nor feel but yet to admit that He or She is great, really helps ?

If so, Wouldn't believing in god then considered as an act of self hypnotism? Why need a belief that can make us feel good and do what is right when we already know what is right and wrong ?

In most ancient religion, God is a symbol of protection and devotees turn to god to seek and hope for protection. Action and values instead were determined by the government and philosophers. EG. Egyptian has no Religious Values as to how the society should live their lives. Egyptian gods are mainly "Looking after" its subjects and giving protection and strength. Even the greeks, the nords, and many others did not tell its subject how to live their life. Only the religions that comes after that and lasted till today advocated teachings and values. Why is that ?
