Hey Bowser, your thoughts about God are a lot different than mine. Your question of, “(One is left to wonder if He made Man in His image, does God live on another Earth somewhere, or what? How does that work?)” is something I see quite differently.

First of all, the word God or YHWH aka Yahweh, Allah, etc. represents the “creator” of the trinity of space, mass, and energy.
Man having also the ability to “create“, then is “like” God in that sense. (Naturally that includes the female of the species also.)

Since we have “dominion” over everything, are we not free to do anything we want, even to the point of ignoring the commandments/ rules/ restrictions/ suggestions or any limitations to our freedom.
I take the word “dominion” as meaning that the creator left everything to us to do as we please. Or to put it another way: After the space, mass, and energy came into existence and mankind developed to a stage where he could manipulate that trinity, then he could develop his knowledge and his wisdom to any extent that he desires.

To use a more modern vernacular, He said: Here, I made this for you, you have the ability to create, now do whatever you want with it.

At least that is how I see it.
