Context is being lost in amongst all that is being said.

God is all knowing yes, but his creation is not all knowing due to circumstance ??

Yes God put the tree in the garden not merely just to put it there but to test man's obedience to his command. Had man had past the test he would have been ready for the next level.

Its like the very child that was mentioned earlier in the post. You tell a child not to go near a fire, because it does not know the danger of the fire or what it can do. So God warns man of the danger of disobedience, "you shall surely die". However some children have to go and touch that fire for themselves to get the message. So man touched the fire of sin and now we the offspring clearly are suffering from that touch to this very day.

Free will comes in by being given an option.
This question as been answered...

God knowing what I am going to do, before I go ahead to do it, does not take away my option. It only means he knows what I am going to do.

What you are questioning is time and eternity.

God does not dwell in time, he dwells in eternity. Everything as been done already, he's just watching us pass through time, he knows the choices we will make and at points he may intervene to steer us from traps that are set that we may come to know him, however he will not take away the option for us to live a life in sin, or live a life unto him.

So he remains all knowing, all seeing... He as the vantage point that no other as.

You speak of logic but knowledge of God does not automatically equate to throwing to the wind logic, just that God's ways are not our ways, his thoughts not our thoughts. So you have to rise to a different plane in regards to logic.
