It is as old as man, but these jack-a-napes think they invented it. Oy Vey! They think if they had been around 3000 years ago everyone would think as they do now. They have no clue that belief in God has been hardwired into us by our Creator, nor do they have a clue that belief in God has functional advantages. Belief in God will never go away despite their beliefs, objections and efforts. They don't even realize what a tiny minority they are.Psalms 14 / Hebrew - English Bible / Mechon-Mamre
1 For the Leader. [A Psalm] of David.
The fool says in his heart: 'There is no God';
they have dealt corruptly, they have done abominably; there is none that doeth good.
Apparently, lack of belief in a God goes back a long time.
