Did Eve eat an apple?

No! "So when the woman saw that the tree was good for food, that it was pleasent to the eyes, and a tree desireable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate." (Genesis 3:6)

No "apple" there!

Fruit as defined by Webster is the ripened, mature, seed-bearing part of a flowering plant; as a pod or berry; the edible, fleshy plant part of this kind, as an apple or plum; the fertile structure of a plant that does not bear seeds; the outcome or result; to produce or cause to produce.

Fruit in Hebrew is periy’ meaning fruit, fruitful, boughs, first-fruits, reward.  As a noun, it means fruit, reward, price, earnings, product or result [consequence of an action, course, or operation].

When speaking of the “fruit” of something, it is in reference to what something “yields” - its “product”, the “offspring or outgrowth” of it.  Disobedience brought on death for the Adam people - male and female!  They were not to eat of the “tree of knowledge of good and evil” nor “touch” it (contact; communicate; correspond) nor handle anything that pertained to it. 

The enemy painted two pictures in the “mind” of the “woman” which were ideas, thoughts, philosophies, and vain deceit and took them in a direction opposite of God, and she began to “judge” what was “good” and what was “evil”.  God’s Word tells us to “judge” no man.  The LORD God only wanted them (the man; the Adam people - male and female) to see and eat of “life” [wisdom; knowledge; understanding; health; joy; peace; immortality]!  When he accepted what the woman offered from the “serpent”, the consequences of “man’s” actions were the fall of the creation!  But praise be to God, He had a redemptive plan in place through Jesus the Christ to restore the creation back unto Himself.  2 Corinthians 5:19  "To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation."
