In agreement God's desire is that people come to Him in faith.
Not in agreement that God wanted people to follow Moses. The children of Israel wanted a mediator and Moses was the mediator at that time (Moses was a "type" ... a foreshadow of Christ).
I do not believe Adam and Eve had children before the fall.
You speculate that the sons of God mentioned in Gen 6 are the children Adam and Eve had before the fall.
However, if Adam and Eve had children prior to the fall, what happened to these children at the time of the fall?
Did God drive them out of Eden as He did Adam and Eve (Gen 3:24)? God would have no reason to drive them out so they could continue to eat of the tree of life.
God also would have no reason to save Noah and his family … He could have just allowed these other children (if your assertion is accurate) to take over where Adam and Eve had failed.
Just some thoughts on your claim concerning Adam and Eve having had children prior to the fall …
No matter what our thoughts concerning children of Adam and Eve before the fall we must agree that God had already laid the line of progression for our salvation. If and only IF,Adam and Eve had children before the fall they would (in my opinion ) played no roll in this salvation plan God had laid down.
Lets me lay some ground work for my point of view.
No 1 Adam and Eve where flesh and blood. The DNA of their blood at the time of their creation would be interesting to talk about, but lets leave that for another time.
No 2 God put Adam and Eve on earth to populate the earth.
No 3 I believe their method of procreation then is the same as it is today. In the first account of creation ,after God had created man and women, He commanded them to be fruitful and multiply . Then comes the second account of man an women creation and from this account comes the question. How much time passed between Gen 2:35 and Gen 3:1? We do know that God commanded them to multiply
before the fall. Question is did they? If they did have children did God reckon their sin back to these children ? It is my opinion Adam and Eve did obey God and produced offspring before the fall. I also believe Adam and Eve had direct fellowship with God. By this I meant they could ascend to His throne or He could descend to them. After the fall however this avenue closed to Adam and Eve , but, what about their children (that is of course you indeed believe they had children ) . If there are children and if these children did not fall as result of their parents sin and, because the whole earth is under bondage because of their sin their parents sin, these children would no longer have a place on this earth. Being still perfect and without sin they could not cohabitant on this corrupt earth with those of us who where under corruption.
I fell if we where allowed to see what Adam and Eve looked like, before their fall , we would not be able to take it in.
I believe We lost far more than what we realize.
One thing we can know , if there are these children , they are stationed above the angles.
