When God created man, He gave him plenty of knowledge.. and whenever He needed more knowledge he was taught by God Himself.. If man has continued along this path, he would have become a scholar and would have deserved to eat of the tree of life and live for ever.. But the man accepted to take knowledge from another source than God and so he began to be ignorant.. His first lesson was from the serpent, and it resulted in eating of the tree of the knowledge and thus he became ignorant. Man seeks knowledge away from God and he only gains ignorance upon ignorance..
