NO, God doesn't need to hide himself. Allow me to take you back to the beginning and show you where man stands with God.
God created a perfect man and perfect woman (Adam and Eve). They were made to live forever with never facing a physical death, in the Garden of Eden. He tells them to eat of any fruit of the trees but the tree of the knowledge of good and evil. You see, they were naked and were not ashamed because they didn't know good or evil, they were in a perfect creation. Then comes the serpent (Satan) which means in Hebrew "the enemy and adversary". and you know the rest. Now sin has entered a perfect world. A holy righteous God told Adam that he would die if he ate of that tree. Now man has sinned and must now face a physical death. Whereby sin entered into the world by one man, all have sinned and come short of the glory God. This is where all mankind stands now before God. A sinner in need of a Saviour, and God has provided by the sacrifice of his son Jesus Christ. For God so loved the world he gave his only begotten son that whosoever shall believe in him shall nor perish but have everlasting life.
God has never failed man, man has always failed God, and God has always made a way for us. The love of God goes beyond human comprehension.
The word of God cuts to the bone convicting of sin, through our God-given conscience
So if we can say "God is imaginary" enough times, we can kill the conscience that declares God to all mankind.
That little voice in the skull is the conscience that divides right from wrong. No science in that.
So we agree this conscience you posted of earlier knowing of right and wrong are a gift from Satan? Morality thus would be a gift from Satan because without him we wouldn’t know good from evil. And do you see apes as a perfect creation? Better than man? Also before the fall of Adam was he incapable of doing wrong or did he just not know what he did was wrong? How is an ignorant person perfect?
