The great thing about this universe is that it is far stranger than we might think. For example, the laws of physics as we know them break down when applied to the first few seconds of the universe. Time itself becomes broken, and calculations concerning the dimensions we know fall apart. This has aggrivated Stephen Hawking to the point that he has developed the concept of imaginary time, which does not actually travel from the past to the future (re: a state of active entropy) to define the origin of the universe.
Using Hawkings imaginary time model, you basically lose a universal beginning point. The universe itself has no beginning, forming not a line with a starting point (that is often conceived by the religious and cosmologists) but instead forms a bowl shape, never reaching a beginning, but instead just existing. While sounding some what far fetched, the concept of imaginary time solves many of the problems of the universe during its first few seconds of existance. It's hard to wrap your head around because we live in a progressive time line. And yet as hard as this is to imagine, God is even harder to understand.
Every single individual that has ever lived has a unique concept of God (gods). My God is not the same as yours even if, by chance, we worshipped the "same God" in the same religion. We are each unique, and even atheists have dissimilar concepts of how they view the god they do not believe in. This leads me to belive that God cannot be completely conceived in the imagination of humanity to the fullest extent. Instead, we each see a small portion of God, relative to our experiences and teachings. Our God is not the complete God, because God is beyond us.
This in itself leads to many, many arguements about who is the real God, what God means to us, and how God interacts with us. Some will claim that faith alone is enough, as they view some notion of an active mystical man in the heavens, watching over us. Some will claim that God cannot exist, because their limited view of God does not work within the realm of understanding they have.
I think God is all this and more. The fact we as a species can conceive of God exposes that we are aware of some greater mystery to existance. It is within this mystery that we will find God. Science, which strips away the mystery, reveals a very limited and small amount of Gods 'footprint', but it can never destroy God... only reveal the mystery of this universe in which we live. Science is the ultimate search for God, it is sciences very nature to admit to the mystery of the universe.
Good luck with your search... I need more coffee.
