That God does not exist

Preliminary RemarksIn this debate, the burden of proof is on me to show how we can know God does not exist. My opponent needs to show that there is the possibility of God existing despite my proofs to the contrary.All the standard debate rules apply, although I don't think sources should really be an issue given that metaphysical arguments are no more valid if cited on another website. Forfeiting a round means forfeiting the debate.For the purposes of this debate:* "Exists" shall mean being an entity, according to objective standards.* "God" shall mean an entity that has the attribute of perfection for eternity. This is to direct this motion at the widest possible range of religions. I will use the neuter pronoun "it" when refering to God for this reason. While I use the singular pronoun, the arguments can be applied to polythiestic religions too.* "Perfection" shall mean being optimal. Something that is best possible alternative is an attribute of a perfect being.Argument 1: Omnipotence ParadoxWe can know God does not exist because the attribute of perfection, which defines God, is self contradictory. It implies, for instance, omnipotence, that is, the ability to do anything. Omnipotence is clearly better than limited potency and therefore must be a quality of a perfect being.Hypothetically, then, could a omnipotent being microwave a burrito so hot that it could not eat it? It seems that the answer must be yes, because the being is better if it can cook the burrito that hot. However, it would also be better if the being could eat all burritos. In this hypothetical situation, omnipotence is impossible, because one cannot both create an uneatable burrito and be able to eat all burritos.Variations on this argument include creating unliftable stones, creating things so indivisible it could not divide them (*cough* atoms *cough*) and my personal favorite - could God create a debate argument so strong that it itself could not rebut it? The general form is, could God create a limitation upon itself.If omnipotence is hypothetically impossible, then it must be hypothetically impossible to be absolutely perfect, because perfection requires optimal potency, which has no restrictions. My opponent needs to tell you why this hypothesis is plausible, given that a simple burrito proves it wrong. Remember - God needs to maintain its perfection for eternity, not be limited in any way ever. Therefore, hypothetically, God could not create a limitation upon itself. Therefore, God is not perfect. Therefore, God is not God.Argument 2: Argument from free willSuppose you're hanging out with God one day and ask it whether Barack Obama will send you a free bus card tomorrow. God will then issue a great profound "NO - he has more important things to do". This is because God must be able to know these kinds of things, because if it couldn't it would be imperfect. Therefore, Barack Obama is compelled (or not compelled) to not send you a free bus card tomorrow.Here's the problem - Barack Obama may have free will. This is a paradox - therefore, if I can disprove predestination, I have disproved God.Now let's change the situation a bit. Let's say I get cunning and ask God whether it will send me a tasty blueberry pie tomorrow. God will then issue a great profound "Yes - free blueberry pies for all!" God must know what it will do, otherwise it would be imperfect. God therefore can no longer change his mind. God therefore is predestined to give me a free blueberry pie, just like Obama is predestined to not give you a bus card.However, free will is desirable to having your actions constrained. God would be more powerful if he could choose to not give us all blueberry pies tomorrow. Therefore predestination must be untrue for God - that is, God has absolutely free will. But if God has free will, he is not all powerful. Therefore God cannot be perfect. Again.ConclusionWhat both of these paradoxes show is that no entity can possibly be perfect. However, this is a fundamental requirement of God's objective reality. Therefore we can know that God does not objectively exist.I look forward to hearing my opponent's refutations and wish him good luck for the debate.
