By the definition of God as omniscient and omnipresent, beyond the bounds of time and space, God cannot exist. The term exist means in Latin to stand out, ex-stare. So anything that exists stands out in time and space, limited within the bounds of its being, an object of material substance subject to the chemical processes of change in the flow of time.
God could be said to subsist, from the Latin to stand under, sub-stare. God could be defined as the substance of existence.
Aanaxagoras is thought to be the first to formulate the concept of the Creator Mind, which Aristoteles called the Demiurgos, the craftsman. They argued that the mass of substance was without form, and the Mind, the unmoved Mover, sparked the mass to start processing so that all things emerged from the chaos and took on temporal processes of change as living things.
I am agnostic in that I do not know if that Mind is at all conscious of my existence, except perhaps through my own self-awareness. So as I get to know myself, God gets to know itself. So I could be said to be gnostic.
God being my friend and guiding my way through life is more of a socio-political concept, the "leader" of a group, the chief of a tribe, the pastor of a congregation, the boss of a company, the mayor of a town, the king of a nation, a living man who follows the example of Jesus as the anointed leader who takes care of his people, and is willing to die to protect them.
