That's conjecture.
In Genesis 1, humans were told to go and populate the earth:
To be clear - Adam and Eve - only the two - were commanded to "be fruitful, and multiply, and replenish the earth, and subdue it".
Even though I do believe that this is a command to procreate - among other things - that could just be my interpretation - perhaps the being "fruitful", "multiplying", "replenishing" and "subduing" are all references to things He wants them to do to the Earth?
Either way - I believe that Genesis 1 is a record of the spiritual organization of the Earth and all things on it. A sort of "setting the stage" Creation event.
The start of Genesis 2 makes it clear - to me at least - that it was a spiritual organization - because He had completed the work of Genesis 1 and rested yet all that took place
before any plant or herb was planted and
before there had been rain on the Earth and Man to till the ground (Genesis 2:5)
And just because God commanded them to do something - that doesn't mean they could or did do it.
I mean - Adam was also commanded not to partake of the fruit of the Tree of Knowledge of Good and Evil in Genesis 2 - but he did so anyway.
And the fact remains that the Genesis account does not record Adam and Eve "doing the deed" until after they were expelled from the Garden (Genesis 4:1)
Now - this could mean that Adam and Eve just decided to wait until that time - or the record was sparse on those kinds of details until that time - or they couldn't have done it until they gained a Knowledge of Good and Evil and became subject to death (mortality).
Considering that the commandment to be fruitful and multiply was the first recorded commandment given by God to Man - I don't think the record would have missed their first fulfillment of that command.
And what possible reason would Adam and Eve have to wait to fulfill that commandment until after they had left the Garden?
And I also find it strange that God would wait until after Eve had been deceived by the serpent and they partook of the fruit before He placed the "enmity" upon the seed of the woman.
I mean - what was that about?
I hardly think people could do that, with only just the two of them.
Conjecture!
Man - people are quit to say something like, "You can't believe that because it wasn't recorded exactly that way in the Bible!" - when someone says something they don't agree with.
However - when it suits their own purposes - they are quick to add their own ideas.
If I can't believe that Adam and Eve were incapable of procreating in the Garden - even though it does not record them doing so until after they left - then why can you believe that there were more people around than the Genesis account records?
Genesis 1 never said that people would be made from earth, dust or clay.
Correct - and I believe that was because that was a record of the spiritual organization of Man - not the physical formation.
Genesis 1 never said they were immortal.
It also doesn't say they had sex either - but I'm assuming you believe that they did?
To get to the idea that Adam and Eve were not subject to death until they partook of the fruit - we go to the New Testament.
"But now is
Christ risen from the dead, and become the
firstfruits of them that slept.
For since by man came
death, by man came also the
resurrection of the dead.
For as in
Adam all
die, even so in
Christ shall all be made
alive." (1 Corinthians 15:20-22)
The Apostle Paul taught that it was Adam - not God - that caused death to come upon all of Mankind.
And it is interesting that death is attributed to Adam - and not Eve - considering that it was she who first partook of the fruit and offered it to Adam.
The answer to this distinction may be found in Paul's epistle to Timothy,
"And Adam was not deceived, but the woman being
deceived was in the
transgression." (1 Timothy 2:14)
She had been deceived by the serpent when it claimed that she would not die if she partook of the fruit.
It is our ignorance, doubt - our faith - that saves us from condemnation.
For Adam was
not deceived. He
knew that his partaking of the fruit would cause death to pass to all Mankind.
Therefore - the death of all Mankind is attributed to him - not Eve - or God.
When God first created Man - they were not subject to death - it was Adam - by his willful act - who caused death to come into the world.
And I believe that he did that because he wanted to remain true to the first commandment God had given to him - to be fruitful - and he could not do that without Eve.
Which is why he said, "The woman whom thou gavest
to be with me, she gave me of the tree, and I did eat." (Genesis 3:12) (Bold and italics added)
He was explaining to God - with complete honesty - why he decided to bring death into the world - to remain with the mate God had given him - to be obedient to the first commandment.
And that was the reason why I believe God commanded them to be fruitful and multiply during the spiritual organization - even though they were incapable of mating at the time.
It was the motivation of that first commandment that gave Adam the reason to willfully choose to enter into morality - to be with Eve.
I believe that God set everything in place for Adam and Eve to Fall - and gain Knowledge of Good and Evil. It was all part of His plan for them to become like Him.
And there were no Garden of Eden too in Genesis 1.
Correct - because there were no physical plants, herbs, rain or Man upon the Earth yet.
Genesis 1 is describing a spiritual organization.
And the order of creation is different in Genesis 2, when you compare the two chapters together. The inconsistencies and contradiction are there.
Correct - because they are describing two separate and distinct Creation events.
This is why there are 2 versions of creation in Genesis.
I disagree - two different Creations - not two different versions of Creation.
I mean - in Genesis 1 - there was "light" before the Sun and Moon were placed.
What was the source of that light? And why wasn't it mentioned again in Genesis 2?
And Genesis 2 never said they were created "immortal" at the start. That's just more Christian misinterpreting the text.
We have our reasons for believing it.
