Atheism can't exist without evolution. Atheism is needed to justify absolute state control of its subjects. Look at the history of the persecution of religion by the Soviets.
And why is atheism needed to justify absolute state control of subjects? Religion has a long a brutal history of being used as a tool to enforce absolute control over people.
Atheism works better - there's no higher ideal that the state is supposed to be subordinate to. So the State can replace God entirely. More efficient than being merely a middleman.
What do you think Big Brother is?? All knowing, all seeing, all powerful, the arbiter of Truth... If that's not a replacement for God then we have different definitions.
Its Religion that has been abused for propaganda. Its books and authorities that abuse the people. The bible is a hoax that was invented after Religion to control the sheeps.
