You could, yes.

Well, the difference is that atheists won't believe in the existance of God because the have no proof of such a being's existance ... believers will, uh believe, that there is a higher being despite the absence of evidence.

Essentially, I might say that while both group start in the same position (absence of evidence) they take their beliefs to the opposite ends of the spectrum (namely, the existance or non-existance of a higher being).

Of course, like you said, logic and religion don't mix.
