Maybe The One has also given visions to the prophets of scripture. Is it possible that he is the biblical God?
Not in my view, no. The One is just an alien, nothing more. It's not God. Like McCoy said, what does God need with a starship? The very fact that The One demanded one is pretty much proof that it isn't God.
If God tells the world that He is omnipotent, omniscient, omnipresent, eternal, and the creator and lord of the universe, should He be believed?
Sure. Why not? I choose to believe God, but not this thing. God acts out of love and compassion. The One is simply a mad alien who attacks people - and needed to be imprisoned
for something. Just because it says it's God, doesn't mean it is.
