I was thinking recently about those things we do instinctively as opposed to those things we can do only after being taught to do them, and what it may indicate about natural versus unnatural behaviors.
When babies are born, they can breath, hear, touch, eat (swallow) and defecate. They can even swim. They can see, but not very well at first, and certainly have no frame of reference to interpret what they are seeing. Without instruction, they are able to crawl once they get their arms and legs under control. They can also make noise.
But they cannot speak in a language, not until they are taught to do so. They cannot eat with implements until shown how. They can only use a bathroom once instructed how that works. They also do not instinctively pray or know of any god until taught about religion.
Instinctive behaviors are common to all animals. Taught behaviors such as spoken language and social activities are unique, for the most part, to humans. Instinctive behaviors are natural. Taught behaviors are unnatural.
This is why I don't believe that religion is a natural state for humans. It is not instinctive. If god were a fact of life like breathing or eating, babies would pray and worship god without having to be told how to do that.
Belief in god(s) is a learned behavior, and as such is on a par with driving a car or speaking French. You must learn about it before you can do it, and once you can do it, it remains an option for living, not an essential activity for life.
I know the christians and other theists won't agree with this, but what do you other free-thinkers believe? Am I being reasonable in my assessment, or am I way off base?
