I think to answer the original question, is that atheists don't have a horse in the race so to speak. We have no dogmatic sense of loyalty to any method of the origins of the universe or any phenomena that occur in it. If there is a creator (big if) and it could be supported with actual evidence (not blind faith), the majority of us would become theists. We aren't trying to prosecute anyone for their witch-craft, we are seekers of truth. We challenge everything. We use discourse, evidence and reason to support what we believe. If we are challenged and fail we will adapt our views to the new evidence. If there isn't a creator (small if), we aren't justified. All that means is that we accurately assessed a situation that was later supported further.
The question is a silly one to ask.
