Hi Cedars
My personal understanding of this is as follows. We were as animals i.e. without conscience. Knowing the difference between right and wrong is to gain one. Therefore the lie isn't and Jehovah said as much before tossing us out to stop us eating from the tree of life.
Genesis Ch3 v22-24
HE then tested Abraham before commiting to sending His own son so that we may gain eternal life.
