Slightly on a tangent here...
Talk of a "god" involves clarification. It is possible to talk of god as a moral idea or talk of god as, say, a necessary end to the debate of ‘where did it all begin?’, or both. Obviously much of the time we are talking about both. However, I feel an athiest is essentially just denying the possibility of a moral god.
Satre esstentially bases his entire moral philosophy on the non existence of a moral god, placing moral responsibility on the individual. You have to decide what is right or wrong.
On a side point many philosophers have seen the idea of a god as necessary to explain questions like, 'why/how does existence exist?' This goes no further to explain whether this god carries moral connations, although many of those philosophers believe it does, but it doesn't necessarily have to.
Therefore, in some sense you could be an athiest and argue for the existence of god.
