> Although evolution doesn't have to lead to the conclusion that there is no God, we happily assume it does---because then we can all be our own gods, making up our own rules.

That's insulting, and (more importantly) it doesn't seem to have any factual backing. Got evidence? Because I don't know a single formerly-religious-person for whom that sort of thing was even a consideration.

And come on, everybody makes up their moral rules or inherits them from their community, or usually some combination of both. Some of them attribute the results to God, but the difference is minimal.
