If the number one predictor of which God someone believes in is what culture and time period they happened to have been born in, what does that say about the actual existence of a deity?
Shouldn't a universal, ubiquitous, loving, caring god have revealed herself in a consistent manner throughout the ages? To all the people of the world in all times?
Not just to a few chosen tribesman 3500 years ago in a very small part of the world.
These chosen tribesman were left with the task of using word-of-mouth to prevent the rest of the world's people from suffering eternal damnation. But they didn't care about us. All they cared about was killing the people occupying the lands that gawd had promised them.
