Strong and Weak Arguments

[robvalue]

Here's a very simple, strong argument against a single deity that has (successful) "personal relationships" with people.

This deity tends to share the opinions of each person, while they disagree with each other.

Something is clearly very wrong with these relationships.

This is largely what I meant by 'cultural norms'. Religious variants tend to cluster geographically and culturally. It strikes me that if there was a single deity who  took  any kind of an interest in human affairs, you wouldn't have Hindus clustered in the Indian subcontinent, Buddhists in East Asia, Muslims in the Middle East and Africa, Christians in Europe and the Americas, etc.   In fact,  if the determining element of religious belief was anything other than cultural inertia, an Eskimo would have the same religious views as a Kalahari bushman.

Right. If anything, it points to numerous deities all battling for power. That would be a far better explanation. The idea that it's "the same God" everywhere is absolutely ludicrous beyond belief. Unless it's a god that enjoys confusing people and watching them kill each other over differences in opinions about it.
