"Why Believe in God" ad campaign

[Alex]

If modern morality derives from ancient religion, where did ancient morality come from since societies have been around longer than the religions we're now relying on?

I'd argue that rather than even the godless sneaking peaks at religion for how best to behave, religion instead simply declared themselves the inventors of how people generally behaved anyway.

As evidence of this I'd offer the fact that when societal norms change extensively it is frequently religion scrambling to catch up and then eventually stamping the new norm with the label "proper god-fearing behavior."
