The belief of God has to be a personal thing - you follow one or don't believe it. For those who believe that there exists a God - you never saw Him, you never heard Him and you never follow what you believe He said you to follow. You will continue to preach irrespective whether or not God appears before you. God has to prove that he is God even if he appears before them. Quite materialistic. They just believe what they believe but not believe enough. If they learn to simply recognize Him, they will simply recognize God in them, you, me and anyone who stand before them.
Another view is the view of believers world. Believers believe that their portion of elephant is real elephant and they didn't explore other areas of elephant. The religion they portray is their perception. They are atheist with respect to other religions. The man has transformed this world a mess, even if God appears he would think to destroy this world rather than brining in order. The entropy is so huge now and tomorrow it will little more than today.
The state of non-believers is more pathetic. They never saw God and they tend to believe there isn't a God. They have a stigma that they are rational and they are so much glued to it like the believers. They may be rational but not rational enough. The rational thinking doesn't help to reduce the entropy rather adds to its growth. My three old nephew is so intelligent to believe that there exists a country called Canada and he believes that one day he will travel (just for sight seeing) to see places and in order to do that he has to study well and conduct well. It is the same belief that astronauts have on an alternate earthlike planet. If a belief gives you a good feeling, put you on the ethical orbit, makes you to find an inner piece, make you progressive and make you to handle uncertainty, you got to believe that it exists even if your cognition says the other way. The thing can be God or love or something else. Belief is superior than the fact.
The belief shouldn't be a blind one and rational shouldn't too rational. The believers should learn rational thinking from rational thinkers and the atheists should learn the importance of belief.
The very argument whether or not God exists is insane and inappropriate.
