All Knowing Creator?

Is god all knowing?
If so why did he ask adam if he had ate from the tree of knowledge of good and evil? Shouldn't he have known?

GOD IS ALL KNOWING AND NOT ALL KNOWING!!!

Take the computer game Grand Thief Auto. The creators of the game know all there is to know about the game. So the know the location of secret weapons (since they placed the weapons there in the programming), they know the best practises or hints and tips (so they could tell you how to achieve immortality etc), they know all the cheats etc. Making them ALL KNOWING in the "Grand Thief Auto Universe".
However because they have given the player "free will" or the ability to do as they please on the game the Creators do not know what we are going to do when we pick up the control pad. Although they are all knowing they do not know if we are going to try to complete missions, Just randomly kill people.

Since this is equivalent to the God all knowing problem, we can use modeling to help us solve the "Is god all knowing" problem. Or as the egyptians said "As above so below".
