I could say that this "belief" you say is a fine way to put it, but I personally do not like to use the word because in my opinion (as I've already said) religionists have made it almost utterly useless and will jump on any and all atheists who even mention belief "see see see YOU DO believe and that justifies MY belief".....
Well I do my part; when asked if I believe in evolution I say: "No! I
accept evolution from the evidence. Belief is for when there isn't enough evidence."
Given that there's plenty of incidents where we don't have enough evidence, I think there's room left for the word 'belief' to be usable by non-religionists. You shouldn't let them hijack it.
