God, the absolute reference of existence

To say "Universe exists" without reference, is like to say " A car is moving" without reference, both have no meaning.
Every event in space-time exists with respect to another point in the same space time, but considering all space-time points (Universe) and thought in its existence, we would discover that Universe existence needs a reference, otherwise, it would has no meaning!!. This reference mustn't have any need to any reference for it existence meaning. The existence reference must be independent in its existence of any other existence in the Universe or/and the Universe existence as a whole. This reference must be not inside universe (nor outside it!!) and it gives every thing its existence meaning from referencing it to the reference existence. This reference is GOD, the creator of Universe. No Universe's existence is possible without God, but God's existence is possible without universe!
