God is an entity possessing one or more infinite attributes - omnipotence, omniscience, omni-benevolence, etc. Let us assume, for the sake of argument, that these infinite attributes are composed of discrete units, each unit being enough of God to produce and sustain one human-like creation.
God: 1 2 3 4 5 -> ∞
God "spends" one unit to create one person.
God: 2 3 4 5 -> ∞
This does not diminish God at all. God still has an infinite number of these units to spend. It doesn't matter how many people God creates, there's still an infinite number of units left over.
God: 193 -> ∞
This is true even if God spends an infinite number of units to create another entity possessing one or more infinite attributes or to create an infinite number of human-like persons. Infinity never runs out. This leads us to one of three conclusions:
1) God is not infinite. In which case, why worship something as God that is merely more powerful than we currently are? Someday, our power may very well rival or outstrip a God of this type.
2) God chose, for whatever reason, not to create peers who could interact with God on God's level. Why should we worship a God who deliberately creates, inflicts suffering and punishment on, and demands worship from, people who are literally infinitely weaker and helpless in the face of God's will? I, for one, choose not to worship a divine psychopathic narcissist.
3) God does not exist. The universe is limited, and so are we, because of the boundary conditions of existence. There's only so much to work with because of the nature of the universe.
