I'm sorry you don't like those. Here are some others; God is: --"the essence of life" (Henry, 2002) --the unity of all that exists (Spinoza) --the Fist Cause of all things (Aristotle; Aquinas) --the condition of possibility of any entity whatsoever (Eagleton, 2006). Take your pick.
Don't force your dogma on other people. If you believe so strongly in your god then you wont need reassurance that others are believing right beside you.
or they just don't find a good reason to believe he does and don't care. lol. you are assuming you know God exists and while I agree that a creative being of sorts exists, we do not know.
