There is nothing for an atheist to back up. They are not making a positive claim. The one that makes the positive claim bears the responsibility to back it up. An atheist just doesn't think theists have done that.

I'm sure most atheist believe in evolution. The evidence is overwhelming for it. But there is no requirement for an atheist to believe it.

No it doesn't. Not having a belief in a god doesn't dictate any way you should live your life. There are no set of rules you must follow.

There is nothing to prove in atheism. An atheist doesn't say that no other view could possibly be right. They just say that the evidence put forward by theists isn't convincing.

And nothing in atheism says you have to make others believe you are right to reject the belief in gods.
