"let 's take a look at a non-biblical God , then . if such a God exists , what is his definition . can he interact with the physical realm ?"
"Well , your typical diety is generally immortal , omnipotent or nearly so , all knowing or nearly so , and concerned with humanity in some way . Creating the universe is a bonus , but not required . They 're all described as living outside the world , but being able to interact with it . Whatever their relationship with our universe is , it 's clearly outside the realm of science as we know it . What does this mean in terms of proving their existence ? Since their interactions with us are outside the realm of science , science ca n't really say anything unless the dieties in question specifically choose to interact with us in a way which science could verify . That is to say , the existence of any God ca n't be proven against that God 's will , but I believe that if a diety wanted to have it 's existence known than it would certainly be able to do so ."
