Very often atheists themselves admit that they have no evidence of God's absence, but they try to put a different spin on it. They'll tell you, No one can prove a universal negative (like There is no God). They think this somehow excuses them from needing evidence against God's existence. But not only is it false that you can't prove a universal negative (all you have to do is show something is self-contradictory), but more importantly, this claim is really an admission that it's impossible to prove atheism! Atheism involves a universal negative, you can't prove a universal negative, therefore, atheism is unprovable. It turns out that it is the atheist who is believing a view for which there is and can be no evidence.
