Why am I an agnostic atheist? I don't know!

[Ace Otana]

Nothing. It is begging the question: "Why haven't you known of a rational, logical, credible argument for the existence of a god or gods?"

You've more or less given no extra information. A convincing argument is one that is rational, logical and credible - providing that you are rational in believing it - right? So really you have more or less just answered the question "Why haven't I known of a convincing argument?" With "Because I haven't". It's a non-answer.

I love discussing philosophy with you. Stimulates the mind.

"Why haven't you known of a rational, logical, credible argument for the existence of a god or gods?"

Perhaps there is no rational, logical, credible argument for a god or gods. Could you find a rational, logical, credible argument for invisible pink rabbits under the moon's surface? If not, then that is a reason. It is an answer. I do not know if there are invisible pink rabbits under the moon's surface and I cannot prove one way or the other. Since it's so very irrational, illogical and incredible. Perhaps it is impossible to have a convincing argument for it. The very concept defies all reason, much like god does.
So perhaps, due to the irrational nature of the concept and your level of reasoning, you as a rational being cannot find a rational convincing argument for such a concept.

You've more or less given no extra information.

Not entirely. If a claim/concept is without a convincing argument, then perhaps, it is too unrealistic to support rationally. It is an answer.

A convincing argument is one that is rational, logical and credible - providing that you are rational in believing it - right?

I think believing rationally, depends on the likely hood and credibility of the claim. In the case of the existence of god, there is none. We have a reason to lack belief in it. I am an atheist for a reason.

So really you have more or less just answered the question "Why haven't I known of a convincing argument?" With "Because I haven't". It's a non-answer.

Not quite. I haven't found a convincing argument for it due to it's sheer total lack of reason, logic and credibility. Perhaps, due to the nature of the claim and concept, it is impossible to provide a convincing argument for it for the rational to accept and believe.
