Well, we can't say any more than we can say there is no god, there is no afterlife. We can only say there is no persuasive evidence for or argument for it.

If I'm in a political argument, I think I can, with reasonable accuracy and without boasting, put the other person's side of the case at least as well as they could. One has to be able to say that in any well-conducted argument.

Religion is not going to come up with any new arguments.

[E]xceptional claims demand exceptional evidence.

If I convert it's because it's better that a believer dies than that an atheist does.

What can be asserted without evidence can also be dismissed without evidence.
