Becoming a "god" of your own planet, is a little more than "becoming like God.
That doesnt change my relationship to God. To me, you, the earth, the heavens, God is infinite, eternal, from everlasting to everlasting because we are created by him. He will always be God to me and you therefore there he is and always will be the object of my worship.
Why not capitalize He and Him?
Sometimes I do capitalize pronouns when referring to God. Other times I don’t. I think both practices are acceptable. I’m used to reading them not capitalized in the scriptures.
