I was being sympathetic to the difficulty you appear to be having with a pre-sin era. On my side it is a lot clearer how things were and what they will be restored to at the end time.
Perhaps it is the clarity of the understanding you think you have that should make you think again, Isaiah 55:8
For my thoughts are not your thoughts, neither are your ways my ways, declares the LORD. 9 For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. For one thing you seem to be assuming that God's plan is to restore the earth to what it was in Genesis, the bible never says that, in fact Paul tells us in 1Cor 2:9
But, as it is written, "What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him" How could Paul say no eye has seen this, if God's plan is to restore Eden that Adam and Eve saw?
The Bible says death came through sin, that the world is under the curse of the sin of mankind and awaits the manifestation of the sons of God. Your doctrine is the one with presumption and assumption.
You seem to be referring to Romans 8 which makes no reference to the fall and doesn't say the world is under the curse of sin.
But Genesis is not the only reference to the 7 day creation doctrine. In Exodus 20:11 and 31:17 the message is repeated and lest you cannot accept any OT scripture literally, then it is repeated in Hebrews 4:4. But perhaps you also have a Greek interpretation that can explain that verse better..
No I simply read the next couple of verses where the writer describes this rest as one we are called to enter into today.
Heb 4:4
For he has somewhere spoken of the seventh day in this way: "And God rested on the seventh day from all his works."
5
And again in this passage he said, "They shall not enter my rest."
6 Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience...
11 Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience.
Was God's rest on the seventh day over in 24 hours, or is the writer of Hebrews interpreting Gen 2:2 as a picture the rest we have in God through the gospel, an ongoing rest we can still enter today?
With the Exodus references, it isn't enough to take the verses in isolation and try to read them literally, you need to look at what Moses was doing with the references. Was he teaching the history of the earth and six day creationism, or was he using the reference to teach Sabbath observance? If you take a passage that is teaching Sabbath observance and use it to teach creationism, you are actually taking the verse out of context.
I am glad you referred to Exodus 31:17 as well,
It is a sign forever between me and the people of Israel that in six days the LORD made heaven and earth, and on the seventh day he rested and was refreshed. If you want to take that literally, you not only have the Almighty God tired after a week's hard work creating, you have the unchangeable God refreshed after a day's rest.
Well the NT says death came through man, and when man gets it right death will be defeated. Maybe God forget about the animals when He inspired those words.
Apparently after 7 days of work, He does.
Shouldn't our understanding God as the Creator show us how amazingly and astoundingly great God is, instead of leaving you with a God who gets tired after a week's work and forgets to mention animal in Romans 5 (yes I realise you were just being sarcastic

). Death is an enemy to be defeated now, as Paul says the sting of death is sin. It's the problem of confusing what the bible says about the present and the future with what happened in the past. Just because death is now an enemy through man's sin, it doesn't mean death only existed since sin gave it its sting. If there was death before the fall it didn't have a sting and would have been a part of God's good creation rather than an enemy.
It isn't just that Roman 5:12 only talks of death spreading to humans and forgot to mention animals, the way it says sin spread couldn't apply to animals. Rom 5:12
death spread to all men because all sinned. Animals do not sin, they can't sin. Paul is describing the reason death through the world after the fall and the reason he give is one that cannot affect animals. Don't forget that the bible uses the same term death, to refer to physical death or spiritual death, often it is only context that tells us which one it is talking about. In Romans 5:12 the death is one that is a result of sin and only affect humans not animals. Sounds to me like Paul was talking about spiritual death here.
So, are you reading literally or not...?
I am looking at the plain meaning of the text, which is what you need to understand before deciding if the passage is literal or figurative. In Gen 1:5
there was evening and there was morning one day, the plain meaning of the text tells me that what you think is the literal interpretation - this was the first day - isn't what the text is saying even if you take it literally. With Genesis 2 the plain meaning of the text, Adam's creation being described as happening before there were plants, tells me we cannot take both Genesis 1 which describe plants created before man and Genesis 2 as literal history. The plain meaning of the texts contradict each other. Now either God forgot the order he created the world in, and forgot what he said in Genesis 1, (like, as you suggest, he forgot to mention animals in Romans 5), or these texts were never meant to be read as literal history.
