Logic and physical realms do not work in proving God period.The only proof is subjective he is all the subjective ,you cannot prove scientifically that a flower is beautiful,you have to see it ,it cannot even be explained or assumed by logic that flowers must be beautiful ,its a very private experience that is real however not physically ,it isn't imagination but a real common experience of reality that we feel intelligence in life.If you believe in logic or physical proof only then you don't know God. **Update** **The argument** objective moral values where observed by philosophers as static truths in life ,how did they know that ?.They felt first subjectively that there is love and due to that quality ,good things manifested in the physical world ,good meaning solved problems for people.So they didn't prove love exists but observed its results .Now the argument is that because of that commonality of manifestation exist that means that they have been impeded by an intelligent being,just like laws are made by humans. **The argument's failure** Now this argument is clearly an analogy ,but it fails logically because when you say an intelligent being then you have to complete the analogy and say whether that being is born or not ,finite or not,if you say finite and born to avoid superstition then you will go into regress absurdum ,who created him ?.. and if you say he lives in different laws then your logic cannot be applied to him ,if you say he is a being that is the source of all beings,because something cannot come out of nothing then is he something or nothing. So logic seems to go somewhere but it ends up failing. **The experience** So objective moral values are called that because their manifestations where problem solving ,as I said they where felt first subjectively so their existence is only subjective ,there are qualities like Godliness and intelligence,these qualities are real they are God ,God is not the assumption of the subjective ,he is the subjective. The being you are talking about is only a conceptual Idea, a thought that you felt was objectivity true,but in essence its an idea from the logical mind that is true only subjectively in the form of a thought.
