I don't understand your question or how it relates to what I posted. But I'll give it my best shot.Then what is existence? How can it be explained since it comes before and thus beyond logic. (be preserved, even if lack of physical, or even some vision in your head is classified as existing)
Existence (n): "the fact or state of living or having objective reality"
In the context of us, we exist if we're within objective reality.
Defining whether God exists is harder to put into words, but thinking about it the other way, Christains believe that God exists because we can observe the complex design of the universe, none of which is possible if He did not exist.
