YAY!
Seems reasonable since angels were singing and shouting for joy when the foundation of the earth was made.
Job 38:4-7 KJV
(4) Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
(5) Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
(6) Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
(7) When the morning stars sang together, and all the sons of God shouted for joy?
Good quote, Tambora.
I'd like to postulate that it's possible the foundations of the earth, though "laid" on the first or second day, weren't "fastened" until the sun was created. Our current understanding of the Earth/Sun connection says that the Sun's gravity holds the Earth in place, like an invisible tether, suggesting "fastening". And the Sun wasn't made until day 4, the same day as the stars and the moon. We're not told when the planets were made, but it would make sense that it was that same day.
"Morning stars" is an interesting thing to talk about. It might be the planets, as we call Venus the "morning star", and Mercury might also be considered one. If God made the moon and planets and sun at about the same time, then that could be when the foundations of the earth were "fastened".
The sons of God are presumably the angels, so they had to have been made by Day 4 at the very latest.
Neh 9:6 seems to confirm the angels were created along with the heavens, and if they are in heaven or on earth or in the sea, then Exodus 20:11 confirms that everything in those spheres was made in those 6 days.
[Neh 9:6 KJV] 6 Thou, [even] thou, [art] LORD alone; thou hast made heaven, the heaven of heavens, with all their host, the earth, and all [things] that [are] therein, the seas, and all that [is] therein, and thou preservest them all; and the host of heaven worshippeth thee.
[Exo 20:11 KJV] 11 For [in] six days the LORD made heaven and earth, the sea, and all that in them [is], and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
I suppose that the "heaven of heavens" could be a place beyond our universe, where God dwells and where angels are there with Him, in which case it's hard to say if they were included with the things in "heaven".
