Welcome to the challenge to prove the existence of God. This is not a challenge to give an account of rational belief in God, but rather is a challenge to actually prove absolutely that God exists. This would be the sort of proof that shows its conclusion to be true absolutely and conclusively. Now of course, a person could be rationally sure of something that can’t be absolutely proven. For example even the fact that the sun will set within the next 24 hours is something everyone rationally believes and yet is not proven absolutely. It could spontaneously explode before then, etc. So whether you are a believer in God or not, you’re probably thinking, "this is a futile challenge. God can’t be proven absolutely". Well, maybe that’s true, but then maybe it isn’t. As far as I know, no philosopher has been able to demonstrate than God’s existence can’t be absolutely proven. In fact some theologians think God has been actually proven by certain revised arguments. Perhaps they are wrong, but how can we say for sure without considering their arguments? (Kantian epistemology aside) So while an absolute proof may be an audacious effort, I think it’s worth a concentrated try. At the very least, I’m sure we’ll learn a lot on the way.

Let me set some guideline for what would constitute an absolute proof and then also how I expect to attempt constructing such a proof. An absolute proof need not be based solely on mathematical axioms nor empirical observations. All that’s required is a valid and sound syllogism. In other words, an absolute proof would consist of a series of premises that logically deduce the conclusion where each premise is known to be true. A premise is considered known if 100% of people agree that it must be true upon understanding it or if it is the conclusion of other known premises.

So for example, the following is an absolute proof that some "statements are true" is true.

1. Assume all statements are false
2. (1) is a statement
3. Therefore (1) is false
4. Therefore, not all statements are false
5. Therefore, some statements are true

See how it works? We have an absolute proof that some "statements are true" is true. Now let’s start trying to prove God. Basically, I will present a high level proof where all of it’s premises I believe are true, but where they may not pass the criteria of being known unless they are supported by further premises. So then people can email me which premise they don’t believe in, and why it doesn’t immediate ring true to them. I plan to update the proof by either giving more premises to make the questioned premise "known" or else concede that such a premise is weak in which case I’ll open it up others to help give additional premises to prove the weak one. It may turn out that this project of proving God this way will need to be modified. Maybe instead of an absolute proof, I should try a rationally justified argument. But for now, while I’m still idealistic J , I’ll try the proof.

So here is the start:

1. God is defined as an eternal, infinite, unique, Causer of all else exists
2. Whatever might not exist must be caused to exist if it exists
a. Potentials beings can't actualize themselves
3. If something exists that might not exist, then something exists that must exist
a. An actual infinite series of causes is impossible
4. Something exists that might not exist
a. I exist, and I'm not infinite (see (6) ) b. Thus I am a being that might not exist)
5. Therefore, something exists that must exist
6. Whatever must exist, must be without potential in its being (or it could possibly not exist), eternal (or its existence wouldn't be necessary), infinite (or it would have real potential in its being to transcend its limits), and unique (or it would have real potential in its being for differentiation)
7. Therefore, an eternal, infinite, unique, Causer of all else exists
8. Therefore, God exists
