The creation of heaven and earth in the first chapter of Genesis represents the new creation of the celestial church called 'Man'.

131. 12. So, then, because the church comes from the Lord, conjugial love comes from Him as well. Because this follows as a consequence from what we have already said, I refrain from confirming it further. Besides, the angels of heaven all testify that truly conjugial love comes from the Lord; and they testify also that this love depends on the state of their wisdom, and that the state of their wisdom depends on the state of the church in them. That angels of heaven testify to these points is apparent from the narrative accounts at the end of the chapters, which are things I saw and heard in the spiritual world.
