Some religious people still have a problem with that, but this explanation seems to work for me.
Me: “Do you believe in Ra, the sun god?”
Them: “No”
Me: “Do you believe in Zeus?”
Them: “No”
Me: “What about Odin, or Quetzacotl, or Shiva?”
Them: “No, I only believe in the one true god who–”
Me: “So, you’re basically almost as much of an Athiest as me. Throughout history there have been many cultures who have believed in their gods. You don’t believe in any of those gods, and neither do I. The only difference is that there’s one god that you believe in that I don’t. You’re 99.9% towards being fully Athiest, you just have one remaining god that you still believe in.”
This also helps when they start giving reasons for why what they believe is real because it’s in their bible. You can ask if they’ve read all the holy books of the Aztecs or the Hindus. Why would their holy book be true and not those other holy books? If we’re going to say something is true because it’s in a holy book, then you also have to believe the books that talk about Thor and Odin. If they start saying that everything around was created by god, again, which god? The Hindus have a story for how their various gods created everything, so do the Egyptians. Basically every religion has that story. It’s also useful to ask them what they’d believe if they’d grown up in India, or in ancient Egypt or in Denmark 1000 years ago since almost everybody gets their religion from their upbringing.
