Atheism 

Atheism is acquired. It is learned. We are all born with the knowledge of God. It is innate. We might not have God properly formed and identified in our mind, but we know of His existence, we feel His presence. We are aware of His universal supremacy, that something is bigger of first ourselves and then second everything else.

“Children (or societies) have to be educated out of theism into atheism, not vice versa. Atheism always comes later”. - Richard Kreeft

God is intrinsic. Atheism is extrinsic. Knowledge of God is natural. Atheism is a deviation and is abnormal.
