You're just playing silly word games now. If you make the definition of 'god' broad enough then of course they exist but in a completely uninteresting and trivial way. I could say the pebble on my desk is a god or that god means the same thing as "the universe" but what's the point?
All you're doing here is indulging in equivocation and hoping, wrongly as it turns out, that nobody notices. Wordy wibble does not an argument make.
I know it seems like that to you but it isn't silly. The point, NTTS, in the case of the pebble and the universe is deification. God is in the eyes of the beholder. If I say the pebble and the universe are beautiful then, to me, they are beautiful. Beauty exists. If I say the pebble and the universe are my gods then they are gods. Gods exist.
The reason for the inability of atheists to comprehend the very simple term god is that they have been indoctrinated into thinking that God is limited to one example of a god. Do you think I make this stuff up?
1 Corinthians 8:5-6 - For even though there are those who are called "gods," whether in heaven or on earth, just as there are many "gods" and many "lords," there is actually to us one God the Father, out of whom all things are, and we for him; and there is one Lord, Jesus Christ, through whom all things are, and we through him.
Philippians 3:18-19 - For there are many, I used to mention them often but now I mention them also with weeping, who are walking as the enemies of the torture stake of the Christ, and their finish is destruction, and their god is their belly, and their glory consists in their shame, and they have their minds upon things on the earth. (Paul says a person's belly can be their god.)
Exodus 4:16 - And he must speak for you to the people; and it must occur that he will serve as a mouth to you, and you will serve as God to him.
Exodus 7:1 - Consequently Jehovah said to Moses: “See, I have made you God to Pharaoh, and Aaron your own brother will become your prophet. (Jehovah God makes Moses God.)
Psalm 82:1, 6 - God is stationing himself in the assembly of the Divine One; “I myself have said, ‘You are gods, I myself have said, ‘You are gods,
And all of you are sons of the Most High. (Jehovah calls the human judges of Israel gods.)
John 10:34-35 - Jesus answered them: “Is it not written in your Law, ‘I said: “YOU are gods"'? If he called ‘gods’ those against whom the word of God came, and yet the Scripture cannot be nullified, (Jesus refers to the verses in Psalms above.)
Isaiah 9:6 - For there has been a child born to us, there has been a son given to us; and the princely rule will come to be upon his shoulder. And his name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. (Jesus, a mortal man, was prophetically called a mighty god)
Ezekiel 8:14 - So he brought me to the entrance of the gate of the house of Jehovah, which is toward the north, and, look! there the women were sitting, weeping over the [god] Tammuz. (Tammuz was the Sumerian king Dumuzi. Also known as Nimrod in the Bible. The Sumerian practice was to deify kings upon their death.)
