I think it may have to deal with existence. In other words I exist, you exist, to know that I exist means that somehow somewhere there was an entity who first came into existence and this first BEing who came into existence must be GOD. Our existence may go a long way to PROVING that there is a GOD because if we exist, there must have been an entity who existed first.
