Me either.
I disagree. If I can show that my conclusion is true, it doesn't matter if the opposite is true or false. My conclusion is still true. If I have good evidence that god exists that does not mean god cannot exist. If i provide good evidence that my shoes are green I don't have to provide evidence that they cannot be green. Maybe I am not understanding what you are saying.
You don't need a conclusion if you can show your shoes are green. That would simply be self-evident to anyone looking at your shoes. If only God could be as self-evident as your green shoes.
IOW, the claim that because of "A" (your evidence for God) is true, that God must be true only works if you can show how the absence of God can't be true if "A" is true.
See if I can make this simpler. The premise "A" is true therefore "B" is true only if you also provide evidence that "B" cannot be false if "A" is true.
"A" has a level of self-evidence that it need not be proven. If "B" held the same level of self evidence then there'd be no need for the premise.
However if "A" is the only thing provided as self-evident and you are using it to support the conclusion "B" then you would also need to show if "A" is true then "B" cannot be false.
We're not talking about the conclusion "that God exists". We are talking about any evidence used to used to support the conclusion inferred by the premise. You need evidence that the opposite of the premise is not possible.
