Read chapter 3 of Genesis again:
Genesis 3:4-5
4 And the serpent said unto the woman, Ye shall not surely die:
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
Genesis 3:22
22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
You know that Satan often tells as much truth as he can, in order to get you to believe his lie. The lie of Eden is not "ye shall be as gods", but "ye shall not surely die".
