Even if theism is a failure, it's still superior to atheism

[Angrboda]

In reference to God or Gods: "That which cannot be proven must be dismissed as false until proof is discovered."

Really? Limiting your objection's applicability to a specific type of entity without good reason for doing so is a version of the logical fallacy called "special pleading". Pretty sure you are aware that you believe lots of things that cannot be proven such as other people having minds or perhaps that the past is gone is some meaningful sense. Granted it sounds clever, as an atheist meme, but fallacious just the same.

That's an uncharitable reading and does not speak well of you.
