Timeless Creation / Timeless Change

I'm trying to formulate the point that bothers me in several ways out of a limited way of thinking, apologies in advance:

How much time has passed since God created?
If there is no end, then you would not have come to the apparent creation.
If time is limited, then it means that God is limited.
If no time passed, then creation was together with the Creator, so it is impossible for Him to have created it.
If there was no time before creation, then how is it possible that the Creator preceded it? And how is it possible that He did not create and then created? How is it possible that there was change in Him if there is no time. How can change be explained without a time frame.
