@Leadfoot,
There are no "Joes left to their own devices" because every Joe is socialized via the language and customs of his social group. That immersion is usually what
directs their thinking. (Try thinking without language !). Primitive forest dwellers are not going to come up with a 'Jesus concept' out of the blue ! Those, like me, who call themselves 'atheists' are making a social statement with respect to the conditioning of their group. They are saying that such
parochial conditioning is either useless or dysfunctional are far as they are concerned. It is nothing has do with 'evidence' (which lies in the eye of the beholder ), even if some atheists attempt to justify their position that way. The main thrust of the argument is (as stated in the previous post) the recognition of the plethora of religious beliefs conditioned by a corresponding plethora of social structures at the
global level.
