"...God, speaking to the fathers in the prophets, in the last of these days speaks to us in a Son, Whom He appoints enjoyer of the allotment of all, through Whom He also makes the ages..." (Hebrews 1:1)
The Son of God made the ages of time. The Bible tells us that Jesus, the Son of God, is the Word of God.
"In the beginning was the word, and the word was with God, and God was the word....And the Word became flesh and dwelt among us, and we gaze at His glory, a glory as the only-begotten from the Father, full of grace and truth." (John 1:14)
"Who is the image of the invisible God, Firstborn of every creature, for in Him all is created, that in the heavens and that on the earth, the visible and the invisible, whether thrones, or lordships, or sovereignties, or authorities, all is created through Him and for Him, and He is before all, and all has its cohesion in Him." (Colossians 1:13-17)
"There is one God, the Father, out of Whom all is, and we for Him, and one Lord, Jesus Christ, through Whom all is, and we through Him..." (1 Corinthians 8:6-7)
Before the world was created God brought forth out of Himself His Son. Together they created everything.
"In a beginning God (Elohim) created the heavens and the earth. As for the earth, it came to be a chaos and vacant, and darkness was over the surface of the abyss." (Genesis 1:1)
"For thus says Yahweh, Creator of the heavens; He is the Elohim, and Former of the earth, and its Maker, and He, He established it. He did not create it a chaos. He formed it to be indwelt. "I am Yahweh, and there is none else." (Isaiah 45:18)
"Elohim" means mighty ones. "Yahweh" is the formal name for the Elohim. In the beginning of age one everything in our universe that needed to accomplish the plan of the Elohim (mighty ones) came into existence - Science calls this event a singularity, or the "Big Bang".
"For thus says Yahweh, Creator of the the heavens; He is Elohim, the Former of the earth and its Maker, He established it; He did not create it a chaos; He formed it to be indwelt. I am Yahweh, and there is no other." (Isaiah 45:15)
The original earth was created to be inhabited, yet the Bible says it became a vacant chaos.
“As for the earth, it came to be a chaos and vacant, and darkness was over the surface of the abyss." (Genesis 1:2)
That is all we are told about the first age. Apparently some Celestial beings created after the Big Bang lived on the original earth and rebelled against Yahweh. The result was the world becoming a vacant chaos and probably all of the other planets in the heavens. I think this is the disruption of the world (cosmos) spoken of in the book of Ephesians.
"Blessed be the God and Father of our Lord Jesus Christ, Who blesses us with every spiritual blessing among the Celestials, in Christ, according as He chooses us in Him before the disruption of the world (cosmos)..." (Ephesians 1:3-4)
The Earth becoming a vacant chaos brought an end to the first age created by Elohim, the mighty ones of the Bible - God the Father and His Son.
