Funny, that is a similar approach as Theists who have a single position on one topic, God exists. Aside from that, theists come in all shapes and sizes and can believe or not believe anything else, not having anything at all to do with theism.
But the reality that is represented by the concept of God to some theists is the same universe you believe in, except that Atheists perceive the universe in a dualistic fashion, the perceiver and the perceived, whereas some theists realize it non-dualistically.
You dear ST, can not still your mind to know if what I am conveying is true or not, until you do, you can never know. when the mind is still, there is only a unified presence, no perceiver and perceiver, just oneness of existence.
