Fallacy: Burden of Proof
Yours is a variation of example 3.
You must demonstrate the thing in question exists. To expect someone to prove the negative is logically fallacious and dishonest.
From your link.
Burden of Proof is a fallacy in which the burden of proof is placed on the wrong side. Another version occurs when a lack of evidence for side A is taken to be evidence for side B in cases in which the burden of proof actually rests on side B. A common name for this is an Appeal to Ignorance. This sort of reasoning typically has the following form:
1. Claim X is presented by side A and the burden of proof actually rests on side B.
2. Side B claims that X is false because there is no proof for X.
My claim is that God does exist. I have met my burden of proof.
You have made a positive assertion that God does not exist. You have not supported your assertion.
As you have made a positive assertion, asking you to meet your burden of proof is not asking you to prove a negative. All that does is show me you don't know what that means.
You are like a little child using big words to impress people, but are an empty shell, with no intellectual substance.
If you are asserting that yours is not a positive assertion (God does not exist.), then you are asserting a belief, which cannot be proven nor can it be used as a basis to refute another belief.
So, my little juvenile buddy, which is it? Are you positively asserting that God does not exist, or are you stating a belief?
Oh my... So we're once again subjected to Seta's absurdity, despite her having been relegated to being seen but not heard, as is the sustainable state of all children.
FTR: The default anti-theist argument rests within the simple scope of "Nuh -huh..."
What you fail to be recognizing friend is that the idiot Seta 'feels' very strongly that your evidence, failing to convince her to change her mind... demonstrates the failure of the evidence.
Understand that in DOZENS, if not hundreds of threads, across dozens of such sites, I have oft' trotted out a scenario wherein, it is postulated that the anti-thiest at issue is selected by God for an audience.
In the scenario, God comes to the anti-theist and in every conceivable way, demonstrates his status as God; his means... answers every question, performs miracle after miracle... leaving absolutely NO POTENTIAL FOR DOUBT.
I close by asking the anti-theist what would be their response...
Without exception, the response is that they would consider that such was a function of clinical delusion; that such was a manifestation of illusion brought about by some cognitive neurosis; an hallucination...
Whereupon I belittle them for their failure to accept tangible emperical evidence, which is of course the basis of their argument that god doesn't exist... and that they're response discredits them personally along with their ideology and it's principle argument on the whole.
Anti-theists are idiots... and this without exception. And while some argue that many anti-theists are professionals, thus proving that they're NOT idiots at all, but very high level intellects... whereupon I encourage them to read the transcripts of Dr. Michael Newdow as he pleaded his case, contesting "under God" in the America Pledge of Allegience... before the SCOTUS.
That dude is an imbecile of the first order... he just happens to be a fairly high functioning imbecile.
