Is the question of God relative

 I would have thought that if two people hold opposing beliefs about the existence of God, that either God exists (in which case the person who believes in God has it right), or God does not exist (in which the person who says that God does not exist is correct). The question of God doesn't look relative at all. It may be difficult, but just because something is difficult to decide doesn't make it relative. Saying "What you believe is not true" is not a judgment about the person who holds the belief, it is a judgment about which belief is true.
