The Bible tells us that Lucifer once was in Heaven. God was first in Lucifer’s life at one time, and God gave him much. How the Lord dressed him! Jewels and precious adornments, probably worth billions in today’s money, were his.We read God’s words in Ezekiel 28:13 "Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created."
So if God put him in charge of the Garden of Eden and God, being the same regardless, then the Garden of Eden after Genesis 1:1 and before Genesis 1:2 must have been on the earth where God renovated it in his renovation of earth. He created the heaven and earth and it remained the same after the fall of Lucifer but because of sin (which we will address in another post) earth had to be renovated for His creation after the fall of Lucifer.
Scripture tells us that the Garden of Eden was on a mountain top housed on earth but reached into heaven. So heaven and earth were connected (circles crossed over providing a common space known as Eden). In Ezekiel 28:!4 "Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire."
From scripture we find that Lucifer was the highest ranking cherub in God's family.He was given the responsibility of being the watcher of the holy mountain of God, Eden. Therefore, we now can understand that God created the heavens and earth. There was no darkness because no sin. Lucifer was in charge of God's holy mountain that resided on earth.
