[Drich]

noun
the doctrine or belief that there is only one God.

Again their is only one God. God being a title and not a name.

I see where you're coming from, but I find that explanation to be ripe with special pleading and more than a little ad hoc. I'm not particularly interested in debating the issue, just in making an observation. Consider that recognition that we aren't likely to see eye to eye on the topic.

In closing, I'll offer this from the same source you used (remembering that you made reference to three deities):

deity
[dee-i-tee]   Origin
de·i·ty
   [dee-i-tee] Show IPA
noun, plural de·i·ties.
1.
a god or goddess.
2.
divine character or nature, especially that of the Supreme Being; divinity.
3.
the estate or rank of a god: The king attained deity after his death.
4.
a person or thing revered as a god or goddess: a society in which money is the only deity.
5.
the Deity, God; Supreme Being.

These definations are ambigous, and don't confirm or deny anything in of themselves. It all depends on how one wishes to use them. I would say defination 3 best suits the discussion we are having.

Hell is a void or the absence of God.

Sounds like heaven to me.

That is why you have been given this life. For not all want to spend eternity with God.

But Jenga makes sense.

Your "trinity" is beyond silly.
