The following may be hard for some brethren in Christ to understand, however it is written about in God's Word in several places, and I will point to those Scriptures so one can look them up to check me out.
1. There was a previous world earth age that existed prior to the time of Adam and Eve. That was a time when Lucifer was perfect in his ways like God said in His parable using the "king of Tyrus" as a type for Lucifer. This world earth age we are in now is a 2nd earth age. The future new heavens and a new earth will be a 3rd world earth age. (See the Hebrew meaning for "without form, and void", as it actually means in the Hebrew tohu va bohu that the earth became a waste and ruin. A parallel description of God's destruction of that 1st earth age is given in the Jeremiah 4:23-28 Scripture. God ended that time because of Lucifer's rebellion against Him. In Romans 8:18-23, Apostle Paul also showed how God had placed this present 2nd world earth age in "vanity", and in "bondage of corruption", proving that Genesis 1:2 "without form, and void" really means a destruction happened on this earth to end that 1st world earth age.
2. By the time the devil had fallen, and appears in God's Garden of Eden tempting Eve, his new role for this present 2nd earth age is expressed by his name Satan, which means the Adversary. That is the role he became when he first rebelled against God in wanting to be God in the 1st earth age. Even though God does not detail His destruction of that old world in Genesis 1, the 1st earth age when He created Lucifer perfect, but then rebelled, there still is enough Scripture there that points to it. The actual meaning for Hebrew tohu va bohu translated as "without form, and void" is one such example. This means then, that Genesis 1:1 is a declaration of God's 'original' perfect... creation, prior to His placing today's creation in "vanity" and "bondage of corruption" like Paul said.
3. Some brethren (even Bible scholars) who are aware of this in God's Word then make some false assumptions about the existence of a pre-Adamic flesh race that existed in that 1st earth age before Lucifer rebelled. There is no Biblical proof of that, but there actually is Biblical Scripture pointing to Lucifer being over "great nations" in that 1st earth age. And regardless of what one thinks about archeology, some of those ancient artifacts from that 1st earth age still exist to this day (See the parable of Ezekiel 31, which is about Lucifer in that 1st earth age). God's Word instead points to the 1st earth age as an angelic world age on earth. (If you know about the dinosaur fossil footprints with fossilized footprints of humans with a perfect arch inside them, no skeletal remains have ever been found along with dinosaur fossils. Those human-like footprints were likely made by angels.)
4. The idea that Lucifer rebelled with drawing one third of the "stars" (put for angels) with him to earth, per Revelation 12:3-4 with him being that "red dragon", something else very important and related to his being over "great nations" in that rebellion is given. Along with that time, the Revelation 12:3-4 Scripture mentions a beast kingdom having seven heads, ten horns, but only seven heads. That is a one-world kingdom of nations type description. Per God's parable in Ezekiel 28, He even said Lucifer was corrupted by his great "traffick", which means commerce, thus pointing to a time of great world commerce under Lucifer in that 1st world earth age.
5. Per the Revelation 13:1 Scripture, another world beast kingdom is mentioned, which is for the end of this present world. It is to have ten horns, seven heads, and TEN crowns instead of seven. Do you think Lord Jesus is trying to get our attention with that distinction between the number of crowns between the time when the "dragon" first drew a third of those stars in rebellion with him, and then the latter Revelation 13 beast kingdom with ten crowns? I think so, and I missed that distinction for quite a time. And since I had studied God's parables in Ezekiel 28 and Ezekiel 31 about Lucifer in that 1st earth age when he was originally perfect in following God, and then rebelled, and it involved his being over "great nations" in that time, that all the more showed what Lord Jesus was pointing to with that first beast kingdom of Revelation 12:3-4.
6. Understanding these things written in God's Word kind of makes me sick when I hear all sorts of men's doctrines that it is apparent was implanted in the Churches by the children of darkness to keep brethren in Christ from thinking about this matter of a 1st earth age, and Lucifer's status in that old world. In a way, our Heavenly Father has hidden it somewhat also, because without being disciplined in all of His Word one would not be familiar with that old world when Lucifer first rebelled. This is why it is a common practice for most brethren to stay in The New Testament Scriptures, for that's exactly a way to hide these deeper matters written in God's Word. Even Apostle Peter remarked in 2 Peter 3 how some things in Paul's Epistles are hard to be understood. The Romans 8:18-25 Scripture by Paul certainly is that.
7. But now, in our times today, very near the end of this world, that one-world kingdom beast of Revelation 13:1 that's to have ten horns, seven heads, and ten crowns, is being almost completed. Today's globalists behind it call it a "one world government", or the "New World Order". What many brethren miss is that there is no... disconnect between that one world government movement and Satan's coming one-world beast kingdom of Revelation 13:1. Nor will there be a disconnect from that 'old world' beast kingdom Lucifer setup on earth when he rebelled, per Revelation 12:3-4. That includes his being over ALL nations and peoples for 42 months like the Revelation 13:4-8 Scripture declares. That also was what he was over at his original rebellion in the 1st earth age. Thus God's Word actually reveals this great correlation between today's time at the end of this world when Satan comes to be 'king' over all nations on earth, and therefore repeating what he did at his original rebellion back at the 1st earth age. Just as God destroyed that 1st earth age, using a flood long before the time of Noah, God will also end this coming world beast kingdom at the end of this world, but by His consuming fire this next time.
8. By understanding the above events per God's written Word, then you should begin leaving all the fragments of men's doctrines that were gathered up in baskets after the Full Loaf of Bread originally went out to the peoples by Lord Jesus Christ. This matter is the "strong meat", and not milk, so checking me out in God's written Word is going to require you do some homework and discipline yourself in His Word.
