That's not logical. Humans are rational enough to come up with guidelines to follow without the presence of religion. Murder, theft, etc..those are all things that have negative effects on organized civilizations, so we couldcome to the conclusion that those things are wrong or right without the help of any type of god.
We're capable of creating moral absolutes without religion. Athiests know right from wrong or good from evil without believing in god or an evil counterpart, no?
