Perhaps you are right, but my point of view is that what we know about God we know by FAITH. I believe, for example, that God is love, that God sent Jesus Christ to this earth to, among other things, die for my sins. These are my faith beliefs. The nature of God and His ability to transcend time and space are also elements of faith.
Yes, IIRC, quantum mechanic theory has shown that time can go both directions at that level of the physical, we are limited in our realm by 2nd law of thermodynamics to one direction of time. But G-d would not be, so being outside the physical limitations of size and dimensions, G-d can experience all time simultaneously.
