God is a Spiritual Being, Who created Heaven and Earth; Created EVERYTHING! (seen and unseen) without God there is no beginning; so God owns everything.
The simple answer is God has no beginning and no ending. He is the Alpha (beginning) and the Omega (ending). This is why the Bible says, “In the beginning, God created…” (Genesis 1:1). It means He was already there before the beginning. Logically, that is impossible. But then, when you think about God being the beginning, you understand that He precedes all other beginnings.
You also see in John 1:1-3, where the Bible repeats again that not only did God precede everything else, all three personalities of Him, including Jesus were there before the beginning of the Earth.
To keep it simple, let’s look at 5 stages of existence that span eternity:
- Eternal existence of God – no beginning, no ending – Gen 1:1-2, Jn 1:1-2, Rev 1:8; 22:13
- Creation of the spiritual realm – heaven, angels and later hell for fallen angels (satan and his demons) – Gen 1:1; Jn 1:3; Rev 12:7-9; 20:10, 14-15
- Creation of the physical realm – earth, other galaxies,solar systems and planets. Also creation of life on earth – Gen 1; Job 38; Jn 1:3
- Judgment of fallen angels and all humanity – Rev 20
- Passing away of old heaven and earth. Creation of a new heaven and earth. End of rebellion against God’s rule in all realms – Rev 21:1-5
