Genesis 1:1 In the beginning God created the heaven and the earth.
God is eternal, so is there any information on precreation?
This appears to happen before Man was created:
Isaiah 14:12-13 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
Was this in the past or going to happen in the future?
Luke 10:18 And he said unto them, I beheld Satan as lightning fall from heaven.
Is this referring to the encounter with Eve?
Ezekiel 28:12-13 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty. 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.
No doubt the serpent is Satan:
Genesis 3:1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
This is long after creation, but it shows Satan still has access to God’s Throne:
Job 1:6-7 Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them. And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
First mention of SATAN:
1 Chronicles 21:1 And Satan stood up against Israel, and provoked David to number Israel.
It appears before Genesis 1; God had a Kingdom that consisted of the triune God and a multitude of created Angels!
