Sorry folks, you are really not getting it.
To reiterate, naturalists say all that there is in the universe is solely the result of natural processes. For them, only natural processes in the universe are responsible for the generation of human awareness, consciousness, and sentience.
What capricious capacity of the entirely natural universe would ever generate the ability of sentient beings to promote an Almighty Creator?
Sorry, your answers are not even dealing with the question. Why am I not surprised. The following statement of the opening post is a fine example of a self-contradictory proposition, which is a strawman to boot. The question strikes me as ridicule, but perhaps not.
ie can a god exist in non-existance?
A Theistic view of reality says God is a self-existent Being, just as the name "I AM" would indicate. This name also presupposes an eternal-everlasting Being. No beginning, no end. Revealed also is that "in Him we live and move and have our being." This means the finite Universe, no matter how large, is a tiny event relative to the eternal, almighty Being that brought it forth, and who sustains at all times.
If the universe were solely the product of purely natural processes there is no logical reason why sentient beings who are solely natural products should ever even come up with the idea of an Almighty Creator, much less base their entire life on the understanding that the Creator sustains the universe at all times.
Don't believe? No proof? Sorry, there's no good reason to believe a solely natural universe should ever be capable of supporting the idea of an Almighty Creator. But low and behold, the real universe that we live in does. So although I was once an atheist, I will never be returning to that belief system. Beyond that, anyone who knows the Creator must say that the invitation is open and free for anyone who wants to contact Him. Just remember though, demands won't get you anywhere.
