Well, your assumption here is that God is in every sense THERE as much as you are. You think this because you are defining God in terms of Greek Theology -- that God is Omnipotent and Omnipresent. It is these Definitions that give Atheists such a good Run. In Fact even the Greeks had problems with these definitions... they did not do their Thinking at Universities but tended to annunciate all their Philosophies during drunken homosexual parties, when I supposed they could have exercised a bit more care had they been more sober and thoughtful. Anyway, such Theological Concepts as Omnipotence and Omnipresence were almost immediately answered with skepticism and pointed arguments to the contrary... but the boggering drunks really didn't care, did they?
More Modern and Thoughtful Theologies have God as Transcendent, that is, God is Above All, that while God may in certain circumstances arrive at Agents and Agency that do His Work in the World, it is in fact only Agency and that God Himself is not His Own Agent in the World, that there is a separation between God and the World.
If we believe that Greeks -- drunken party queer Greeks -- are the only ones capable of ever defining God, and that if their definition FAILS, then God would simply not exist, then God, well, by failure of the Drunken Fagoty Greek Definition, would no longer Exist. But if we Modify the Theological Definition in order to Fit the Reality, then we still have a God, but we must get used to some certain Facts of Life.
God is not of the World but Above the World. We need to fix a great many of our own problems. What Religious History teaches us is that through Prayer, Penance, Fasting and Sacrifice, certain Divine Agencies are given to the Saints -- Miracles are possible -- but in this Day and Age where there is little Prayer, little Sacrifice, and NOBODY fasts and does penance ( even Catholics since the Vatican II Counsel no longer act Religious) then there really does seem that there is NO GOD.
You get what you pay for. Nobody has paid for God. Not recently. But the History is there.
