Disproving Odin - An Experiment in arguing with a theist with Theist logic

[SteveII]

I just want you to answer this one question, and then I’ll let you have the last word here.  You and Mathilda have a lot going on.

Why should I take seriously the positing of an entity that, by definition, requires no explanation for its alleged attributes and powers, and cannot be demonstrated to exist?

You are right that by definition God has no explanation. But your second phrase does not follow from the first part (or any other logic). In other words, there is nothing in the definition of God that even suggests that his existence cannot be demonstrated. For example, why couldn't God demonstrate his existence by coming to earth and telling everyone? 

Regarding your question "why should I take seriously...?" even if you don't believe, you should understand the concept that a good part of the world believes.
