When and where did atheism first start ?

[Aegon]

Like language. Or math. Or how to behave in a group.

No it's not like language or math because atheism is free thinking and imposing religion on a child is transforming that child from a natural question-poser to a socialized question-rejecter. It is attack on human mind and its capacity to ask and know altogether.

Any belief, or conclusion, you make about something by default limits your question posing, because you take it as fact that does not need to be questioned any further. There are many conclusions and beliefs people have about things aside from the question of whether God exists, which they then teach their children... what makes religion different? You have plenty of beliefs like that; we all do.

I see where you're coming from, but I guess I find it difficult to believe that just because a child is raised to believe a certain religion that they are some zombie with no critical thinking skills. In some cases maybe, but it's hyperbole IMO.
