You are taking away from what was said, by both Satan, and by God.
What was said:
“For God knows that in the day you eat of it, your eyes will be opened and you will be like God, knowing good and evil.”
NOT simply, you will be like God. Nobody said that.
Satan said, you will be like God, knowing good and evil.
God said, Behold, the man has become like one of Us, knowing good and evil.
Ergo, that was NOT Satan's lie.
On the other hand, unfortunately, Satan's lie is repeated to this very day.
