if God exists outside of time + space...how can?

[hypermegachi]

ok...so it's a common assumption that God has to exist outside of time and space.

we also know that sound is just a whole bunch of waves traveling through the air. it must be that these waves exist within time and space, because it takes time for the waves to travel from one point to another across space.

anyways, if God exists outside of time and space, how could He have spoken to Job?

and please...no God can do whatever he wants because He's God type answers.
