Cosmological Theory of Philosophy

The cosmological argument is regards to the existence of a God; a supernatural omnipotent and omnipresent being in a nut shell postulates that "everything has a cause" thus the world has a cause or in this case a creator responsible for its being. The apparent flaw with this argument that many great minds have quickly pointed is that if God is the "cause" of the universe as we know it and if everything has a cause then what or Who created God? In other words is the cosmological theory self-contradictory? Well I'm not going to pretend i know the answer to this question that must have perplexed the advocates of the cosmological argument but let me run this by you all as suggestion. In the case of time, most scientist and philosophers suggested that time was a circular phenomenon rather than a linear function- a very large circle that will avoid any repeats in peoples' events and life in the same life cycle! So what if we apply this to the cosmological theory; maybe the cause and event function is more of a circular notion rather than a linear progression- wherein every cause has an event and every event in turn becomes a cause and vice versa. This probably differs from what cosmological philosophers might argue; that God has no cause but call me part of camp 2- i belong to that camp that suggest that the cosmological argument is sufficient in sort of proving the existence of a God if and only if He in Himself is created by something else as a result of the circular manner of creation and coming into existence. The next can or worms i might have left myself vulnerable to is who then is the creator of God or the cause of God? Well to me; " the lack of proof for the existence of God or in this case his 'cause' is not sufficient proof for his nonexistence"
