That's not the issue.In other words, how could anything but lack of belief be applicable to an infant who is not familiar with the concept of God?
Windshield wipers have the capability of being "on." That's why "off" can be a default.Ok, I thought they the analogy with "sober" would do it, but I'll try again.
Windshield wipers. The default is "off/not activated" but they can be activated later in case of rain.
Now faith in God. The default (from the "factory") is off/not activated, but it can be activated in case of indoctrination.
Does that help?
Your saying a baby doesn't ("theist" = on).
