Theism is a learned behaviour, taught to children. It is not the default position. Religion spawned from asking ‘why’ and since knowledge was limited in the before times superstition came to be. That’s why most societies around the world have differring views on religion, if it was the default state there would be one religion not multiple.
Which is why different regions have completely unrelated gods who directly contradict each other on how god works, what god is, how many gods there are, what god wants, what god doesnt want, what god likes and dislikes, how god made us, how god made everything else, what god intends for us to do, and how god wants us to live.
Because its such a natural thing that we all correctly know intuitively. Right.
