I used to identify as an agnostic for quite a while until I read more and realised that the idea of proposing there is a 50/50 probability doesn't make logical sense. But I sometimes fear that the word 'atheist' may make people think we are suggesting we know for sure there is no god when that isn't really the case. I'd like if there were a better word which helped to encompass the idea that it's 'atheist because of a lack of evidence to the contrary', not because we know there isn't a god.
