Exodus 20:11 says, “ For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested on the seventh day". This implies that God made everything in 6 days, not that he made the heavens and the earth and then waited for a long period of time before creating everything else.

Genesis 1:31 states, "God saw everything that he had made, and it was very good.". This suggests that the original creation was in a state of perfection and goodness, not a chaotic, destroyed state.

^^^^^
Just trying to get you to stretch your brain a bit.
Here's a question that relates to a lot of these timing questions; when did Lucifer fall? Obviously before the fall of Adam in the garden. So in that case, not everything was "perfect" before the fall; even in the garden.
I'm not trying to create doubt, just the opposite. Just keep digging. There are many things we can have assurance of, and some things remain somewhat of a mystery, but that's okay.

Evolution comes in many forms, physical, mental, thought processing, understanding ,comprehension, etc. Here's an example for those that can "process" it in any of these above ways.

We can’t give an exact time of when he fell since the Bible doesn’t say, but most people assume he fell during the Creation week.

I couldn’t see the possibility of a gap in creation either until I really stepped back and took an open minded approach. I’m not sold, but I don’t see how you can rule it out now

Does this rule it out for you?

My question is what happened to or what killed off the in-betweeners?

We don't know how long Adam lived in the garden before man fell. So Lucifer could have fell during the 1-100 or more years after creation before man fell.

Oh, . . . they "evolved" and moved to cities . . . miraculous transformations . . . don't ya think?

They didn’t die off or disappear because they never existed.

I think evolutionary theory is a long working psyop brought on by controllers that want the human race to deny a Creator/Designer

What we call evolution cannot be tested. It is a failed theory at best. They say it is science because they can test it, but they are deceiving. They cannot test their hypothesis of one species turning into another species. All they can test is adaptation to environment; which they claim those adaptations given millions of years can change dinosaurs into chickens basically; thus giving credit to their theoretical "testing"

Recent scientific discoveries in DNA have put the final nail in the coffin for evolution theory. The DNA has information (software). Information and software does not just come into existence; a designer must install it.

Hit the nail on the head.

Snap. Can I help?

This is an interesting post.
It's interesting to see how many different ideas peaple have.
Obviously with different preconceived notions.
One example is the following of Lucifer.
If you're pre conceived notion is that Lucifer is not satan but rather the king of Babylon as I believe from the context of scripture. Then this could change your whole theology of satan falling.
I believe God may have created satan for a purpose. Possibly to test peaple.
Looks at the prayer. Leed us not into temptation.
When Jesus told the apostles how to pray. He knew satan would tept them. Satan even attempted to tempt Jesus shortly after he received the Holy spirit. Faith and the anointing shield you from temptation. That is part of the good news, the gospel. Satan shall be bound for a thousand years. I believe this has happened when Jesus beat death in the resurrection. If you understand the gospel of the kingdom the way that I do, you will understand that when you are Christ's then saton has no power over you.
You have taken on the armor of God and the good news is you are part of his kingdom.
On earth as it is in Heaven.

Do you mean that Satan is already bound for a thousand years?

No. At the very least the possibility is there. Look into it. It’s not sacrilege to look at the Bible through other lenses. I wouldn’t do any of the theories justice trying to explain them because I’ve not spent too terribly much time committing them to memory. There are several that believe Adam and Eve in the garden was a re creation. There are some interesting points to ponder in these theories. Including, but not limited to, the city that Cain went to/built after being removed from his people and the wife he took. Who was the wife? Why does a city need to be built for two people?

I mean that is what I believe. I don't claim to know this as fact. It is my understanding from the scripture.
Christ is king. But in order to be part of the kingdom. You must be born again.
Just like Jesus said to Nicodemus in the Gospel of John. Ye must be born again.

I like your posts Giant Sage.

Can you please clarify your understanding of Lucifer and Satan being different entities? That has never crossed my mind; as I have always considered them the same......,but I'm certainly open to other ideas.

Satan is not bound for a thousand years yet. The book of Revelation is very clear about that. The Apostle John wrote that book when he was exiled on the island of Patmos. He was writing about the future. If Satan was already bound, why was John writing about when he would be bound well after the Crucifixion?

I also believe Satan and Lucifer are one and the same. Lucifer was his name when he was one of God’s angels. But when he rebelled against God, he was cast from heaven and given a new name.
