Dr. Craig is a liar.

[Time Traveler]

God existed timelessly and changeless causally prior to the universe. Atemporal. There was no stream of consciousness or successive chains of thoughts. He knew all truths intrinsically.  

But this directly contradicts what you said earlier in this thread...

If timelessness is not an essential, but rather a contingent characteristic of God, God could have decided to exist timelessly in the past and then decide to create the universe and in doing so became temporal.

[emphasis mine.]

Which is it? Did God "decide" things one after the other, or not? Is timelessness essential, or contingent? You seem very confused for someone who so strongly asserts knowledge of God's nature.

On the A theory, once God created space-time, God underwent an extrinsic change with the new relationship to his creation and in doing so became temporal.

A truly timeless entity cannot do anything, including creating space-time. There is no moment of "change" without some form of time. Without change, there can be no cause and effect. God cannot exist sans universe, then suddenly create the universe absent some form of time to which he himself must be subjected to. You're addressing what happened after God created space-time without addressing how God  could have logically created space-time absent any form of time or change.

On the B theory, you could conclude that God did not undergo any temporal change (neither intrinsic nor extrinsic) and exists outside the block of time.

If the B-theory based on Relativity is correct, then all times past, present, and future have always co-existed and there would never be a moment where a creation event was required, which is why Craig dismisses the B-theory in order to hang on, however tentatively, to his precious Kalam. He would also adamantly disagree with you that God currently "exists outside the block of time," as Craig believes God is now definitely temporal post creation.

So far, you have a God who possibly "decides" things (including, absurdly, "deciding to exist," which itself is a ridiculous contradiction), without any stream of consciousness because he supposedly knows everything, and then you have your timeless, changeless entity suddenly "change" after an eternity of changelessness, magically creating the universe and then deciding to exist inside of it or outside of it depending upon how things pan out scientifically vis-à-vis the A or B theories of time. Your definition of God is clearly self-refuting, ad hoc, and irrational. The scientists you quote don't support your conclusions, and even regurgitating Craig's mantra can't help you here. Who knew defining an imaginary friend into reality could be so difficult?
