Ecco,
Your logic is as stuck to your views as gum to your hair.
if you agree that Matter, space and Time is something that did not exist before it came into being, you will have to admit that in Mere Christian explanations, God is:
not in matter;
not in space;
and therefore also not in time!
You are caught up in matter, because you are matter.
You occupy space, because you are matter.
therefore you are bound by time due to matter moving in relation to each other.
Now, why would you bound the Christian God to Time only, but not to Matter and Space?
Willfull Bias obviously.
God is the I AM, the existing NOW.
We are by caught in Time and age and move through the ages.
If you think Time ran for 12.5 billion years since the Big Bang, and it is evidence that God waited that time to create life 6 000 years ago, it is your opinion.
The fact is that God are not bound by that 12.5 billion years of time, just as he is not bound by the 6 000 years we are living in, and also not by the eons of no time before the Big bang is what I find God telling me.
He is not bound by His creation period.
