Probably in all the other dimensions which are not within the very limited range of our sensory organs. Everywhere and in every thing and 'non thing' - the non things being that which we can't even conceive of, let alone be aware of.
If a tree falls in a forest and there is no one or nothing there to hear it, does it make a noise? No, it makes a vibration. Until that vibration is interpreted as a particular sound via a material sensory organ some would say it doesn't exist. Likewise - and I'm assuming God has created (and uncreated) illimitable universes. So where was God "before the heavens and the earth." Extant and not extant. Everywhere and nowhere. Just "Is."
