Likely in the heavens in the reality for which He created them...I think we all realize that they are able to operate in the earth from there...or at least some of them can?Where did the creator put the angels?
I look at it this way fyi...God being "eternal" existed prior to establishing His "creation"...creation exists in and flows out of God. Creation can be summed up as..."In the beginning God created the heavens and the earth"...including "all" that is within them...technically that is all there is to creation...which by definition of having a "beginning" from out of the person of God Himself...will experience it's ending......is not eternal...only the Spirit of God is eternal.
