What is your “basic” logic for this?
God is all knowing. god knows the future. Because god knows the future there is only one possible way for things to progress. If things progressed in a different way then god foresaw it, then he is not omniscient. So things must progress in the way that god sees them. If things progress always in the way god sees them, then there is no free will because everything has a set path.
In other words, god could not be omniscient while we have free will. I’ve explained this twice now and I have yet to hear a legitimate argument against it, just denial.
God created Adam and Eve in order for them (and their offspring) to live eternally in heaven with Him. However, God wants people to love Him for Who He is; He does not want puppets or slaves so He gives Adam and Eve free will to either accept His command or reject His command about eating from the tree of the knowledge of good and evil. If they eat from this tree, then they will lose their innocence because Satan’s evil will be unleashed upon them. Hell was originally made for Satan and his followers. (Revelation 12:7-10, 2 Peter 2:4, 2 Peter 2:4-1, Revelation 14:9-12)
Read above ^^^ regarding freewill. As far as Adam and Eve, it’s literally impossible for the whole human race to have come from two people.
Anyways, mankind’s closest common ancestors are 100,000 years apart:
en.wikipedia.org/wiki/Mitochondrial_Eve
en.wikipedia.org/wiki/Y-chromosomal_Adam
But, He knew before He created them that they would indeed reject His command and therefore suffer spiritual death. So, because of His foreknowledge since He is all-knowing (omniscient), He provided a plan for them to be redeemed from their sin by sending His own Son to die in atonement for this sin which caused their estrangement from Him. Did He have to do this in order to redeem them? No. He did it in order for them to see how much He loved them. He actually loved them so much that He was willing to show them His great love by suffering death Himself (empathy) in order to reconcile them to Himself again and to be a good role model for them to follow so that they can inherit eternal life when they die. (John 3:16, Matthew 25:34, 1 Peter 1:20) Adam was not a good role model for us. (Romans 5) Christ is. (John 8:12)
In your first few sentences you confirm my argument that we would have no free will.
You’re missing a key component to your story. So, as you agreed, he knew that mankind would fall. So he punishes mankind for something he knew would happen if he created them (remember you said this yourself). Since he is all knowing and knew this would happen, he created man knowing they would be punished to eternal torture. He then sends his son to die for something he knew would happen.
He could have avoided all this if he hadn’t created Lucifer (and as you agreed he can see the future) or by not punishing us for something he knew would happen.
We descendants of Adam, however, do not regain the innocence of the Garden of Eden by Christ’s sacrifice; we now have to take up our own crosses in order to be saved and inherit eternal life. (Luke 9:23, Matthew 10:38) This must be done in order to satisfy God’s Justice. We will be rewarded with heaven and everlasting life if we are approved (found worthy) after we die. (James 1:12)
Pretty sure I address everything here ^^^^
It’s no “skin off my nose” if you refuse to believe as I do. You are responsible for the skin on your own nose.

This responsibility to choose your “own” destiny by your own choices is called
free will.
Again by saying we have free will you are contradicting the points you made earlier in this post.
