If these are conversations you feel you must have IRL, you might start by pointing out to them that they too are atheists when it comes to the thousands of other gods humans have believed in, worshipped, and sacrificed to. The difference between you and them is that you disbelieve in just one more god than they do, and for most of the same reasons they reject those thousands of gods. They indulge in special pleading to give their god a pass they don't give to the others.
And when they start spouting the Bible at you as "proof" of their god, just remind them that the Bible (or Koran or whatever holy book is appropriate to the specific conversation) is the claim, not the evidence for the claim.
