Simple question really.

Genesis 2
17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.

Genesis 2
4 And the serpent said unto the woman, Ye shall not surely die:

As you can see the serpent clearly lied.

God said she'd die that day, and the serpent said she wouldn't die. So god flat-out lied, while the serpent stretched the truth a good bit.

2 Peter 3
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
