Argument for the Non-Existence of God (No. 3)

From Objectivism

P 1 ) The primacy of existence maintains that existence (or "existents") exist (in a mind-independent reality). 

P 2 ) Consciousness cannot occur unless it has something (existents) to be conscious of, and so is secondary and subordinate to the primacy of existence.

P 3 ) The conscious only has this relationship and it is not possible for a conscious to create or otherwise change existents through only its conscious will (through only "thought").  A consciousness does not hold metaphysical primacy over reality.

P 4 ) "God" is ultimately defined in many religions as a consciousness with a "will."

Conclusion:  Since a consciousness does not hold metaphysical primacy over reality and it is not possible for a consciousness to create/change existents through "will" alone, such a god as defined cannot exist.*

Argument for the Non-Existence of God (No. 2)

From Worship

P 1 - Worship ("systemic adoration in a religion") is an anthropomorphic tribal convention associated with humans, and is only narcissistic supply for a human's ego needs.

P 2 - A fully omnipotent, omniscient supernatural being would not require such worship since it is not human and should be absolutely secure and certain of its omnipotence/omniscience.

P 3 -  Many religious texts and doctrines, such as Judeo-Christian and Muslim, claim their god requires such worship.

Conclusion:  Since these gods should not require worship if they were indeed gods as described in  the religions' doctrine (omnipotent and omniscient), these gods do not exist.

Note:  A god not requiring worship (if omniscient/omnipotent) could therefore exist.
