Why is the Earth Formless, Empty, Dark and without shape in Genesis 1,2?
The scriptures (Isaiah 45:18) made us understand that God’s creation is perfect and did not make anything desolate. The question here is why is the Earth formless and shapeless if the creation was perfect.
If you read closely at Genesis1: 2, it says, “Now the earth WAS formless,” meaning something has transpired between verse 1 (perfect Earth) and Verse 2 (Destroyed/formless Earth)
Let’s explain what happened between Genesis 1, 2 that made the earth formless and without shape.
Before the creation of Adam, there were already inhabitants on the earth. These races already existed on earth (pre-admic age). You may ask, who are these races?
According to the scripture, Lucifer (Devil) occupies the cherubim office and an archangel (Ezekiel 28:14).
His job is to take the word of God to the inhabitants of the earth and praises to God; he was a mediator. But instead, he corrupted the word and kept the praises of the inhabitant to him self.
These acts defiled his office with the iniquity of thy traffic, according to Ezekiel 28:18.

At the time, Satan fell like lightning from heaven (Luke 10:18), when he was cast down from heaven according to (Isaiah 14:12, Ezekiel 28:16, Revelation 12:7-9).
The earth was destroyed in God’s fierce anger. The inhabitants were scattered, the earth was a barren waste, mountains overturned, and the light was shut off according to Isiah 24: 1, Jerimiah 4:23-27.
