Atheists claim we are born atheists.

[Y]oung children, regardless of their cultural background, are inclined to believe that they have an immortal soul – that their essence or personhood existed somewhere prior to their birth, and will always continue to exist.

Will Religion ever Disappear

Yes, I remember how utterly shocked I was when at a very young age I asked my father what happens when we die, and he said we cease to exist.

Interestingly atheists frequently claim we are born atheists and we are indoctrinated into believing otherwise. But it seems that we are born with the innate supposition that there's an ultimate purpose to our lives, the Universe and all things. Such an innate supposition seems very far removed from the family of beliefs associated with modern western atheism.
