^ That''s very interesting, but I'm not sure I understand the original premise of either argument.
That's because my purpose was not to provide a full explanation of either argument.
My purpose, as I said, was merely to show that both arguments could be boiled down to a modus tollens.
There is an extensive literature on both the problem of evil and the problem of disbelief. If you're interested in learning more, it shouldn't be too hard to read up on the subject.
Ditto for why would everyone believe in God, if God existed. Goliath, you give no reason why this must be so, either.
See above. I never claimed to be providing a full version of either argument. Merely to be showing that a negative can be proven, by way of a modus tollens, and that two of the most convincing arguments against the existence of God can be put in this form.
You conveniently ignore traditional Christian theological concepts such as "original sin" and "free will", which in Christian theology actually negate both of your premises.
I'm not "conveniently ignoring" anything. Once again: you are misrepresenting my post and its purpose.
I'm fully aware of Christian claims about "original sin" and "free will." In my considered opinion, they're myths, and worse: they're gibberish. And in my considered opinion, far from justifying the ways of God to man, talk of "original sin" and "free will" merely underlines God's monstrous injustice, and the sophistry and pedantry of his apologists.
But my point was not to initiate an argument about the existence of God. If I wanted to do that, I would have started a new thread, entitled: "Does God Exist? Begin."
My
point was to show:
--that it is, in fact, possible to prove a negative, by means of modus tollens;
--and that two arguments against the existence of God (which I find particularly cogent and convincing) can be reduced to this form.
This I did in fact show. Everything else was in the way of personal commentary.
Don't like my opinion? That's tough. It's a free country, and the only tribunal to which I have to answer is my own conscience.

So... Have I got this right (based on the reasoning given above)? (maybe I am missing something):
If Obama's birth certificate existed, then everyone would believe that he was born in the United States. (Or: if birth certificate, then universal belief)
But not everyone believes the birth certificate exists. (Not universal belief)
Therefore, Obama was not born in the U.S. (Therefore, Nigerian)
Yes. You are missing something.
On the one hand, you're committing the same fallacy that Brian committed. You're denying the antecedent instead of the consequent.
On the other hand--your argument just doesn't make sense.
Here--try this:
If Obama was born in the United States, then he would have a birth certificate attesting to that fact.
He does not have a birth certificate attesting to that fact.
Therefore, he was not born in the United States.
That is a valid argument: its conclusions follow from its premises. But I'm not sure it's a sound one. On the one hand, it seems possible for people to be born in the USA, and then lose their birth certificate. And on the other hand--doesn't President Obama actually have a birth certificate? I'm pretty sure I've seen it somewhere online.
And on the third hand: Obama is not God. The problem of disbelief does not apply to him. It's a particular problem of a being that is supposed to have God's combination of attributes.
