For those of us who live in reality- GOD doesn't exist. For those of you who want to live in a mystical based world, then sure GOD exists, but only in your imaginary thoughts, by which have NOTHING to do with reality, because thoughts, desires, will or wishes, have nothing to do with reality. Reality is all knowable, which isn't to say that we know everything there is to know, but means that we know everything there is in reality, at the time we are talking about it.
Reality exists, like the Universe exists and Life on Earth exists. It just does. Nothing cause the Universe to happen, The Universe cause Earth to come to be, and Earth evolved so as to support Human Existence.
Please, whatever you do- DO NOT say that God exists, because the topic 'god' itself is imaginary. It is YOU that make a difference in your life, by using your consciousness, conscience and subconsciousness, in the manner in which you are suppose to in the first place.
There is NO god looking out for Us or anyone for that matter.
