When you think about it Lord Yahweh isn't the only god in our fiction. There were all the Greek gods, Norse gods, Egyptian gods or whatnot. So if one god can exist why not another? So even if you think Yahweh is real, it could be Zeus or Odin and you're fucked anyway for not praying to them instead of Yahweh.
Frankly if you can come to the conclusion of just one god being real, then you can come to the conclusion that none of them are.
