Can you give me an example of what “other deity” you’re talking about, so we can then confirm whether or not you’re being accurate when you say that I “have no problem dismissing those as implausible.”
Bor from Norse mythology, Alum from the Egyption creation story, and Brahma and Vishnu from the Hindu religion are some examples. There are many more. All of these are dieties attributed with and having the power to create the world. Can you prove that they do not exist?
