As I said above, in Gen 1:1, “the heaven and the earth” was probably meant as a compound phrase with a singular meaning, a hendiadys, standing for something like “the universe” or “the world.” Moreover, the “heaven” that was created in 1:1 was simply the vaguely-conceived upper regions, perhaps the unseen cloudtops above the proto-earth. As to “Heaven” in the sense of God’s spiritual dwelling-place—that is, assuming that we should assume that God’s dwelling-“place” is indeed spiritual and not located in any physical/spatial relation to the earth—clearly it must already have existed before 1:1. Of Jesus, Paul said, “by him were all things created” (Col. 1:16), and “he is before all things, and by him all things consist.” Hence, if it must be said that the Godhead dwelt “somewhere” and “before” the creation—though perhaps this makes dubious sense—then that place existed before God created “the heaven and the earth.” So we are really dealing with two, or perhaps three, concepts of “heaven” in Gen 1.
