But it (atheism) does influence how you live your life.
This is a common misconception among religious people. Atheism is a belief there's no god, and nothing more than that. It isn't, in itself, any sort of moral compass.
We atheists don't need an invisible policeman in the sky, nor an old (and morally questionable) book, in order to know how to behave ourselves properly.
On the whole, atheists are more intelligent and better-educated than are religious believers. Perhaps religion plays a useful role in regulating some members of society. But, in general, I see religion as a force for evil in human societies.
