Well I am not the designated spokesperson for "the godless". Speaking personally, however, I have no idea "how it all began" and frankly, I don't even care. Maybe if that was the biggest fish I had to fry, I'd spend more time trying to figure it out, or maybe I'd take up knitting, I'm not sure.
The way I see it, however, whatever "it" was, it happened, and we're here, and we need to move forward, not sit on our thumbs and ponder what pushed the "on" button a gazillion (currently) unknowable years ago.
I don't think that points to a sentient "creator" (or series of creators), however.
