Here is the thing. You can\'t disprove something that has not had evidence offered. Thats what the word means. The prefix \'dis\' means to remove. So to disprove something means to remove or refute proof (in this case evidence). Trouble is claims for God keep getting refuted. But the theists don\'t play fair and keep insisting that there is a God even if they can\'t show any evidence that stands up for it. You cannot disprove what has not been proven. Because there is no significant evidence for God it is an unsupported claim. There is no need to disprove it because it has not been succesfully proven. This is why the flow of burden of proof is laid out the way it is. The positive claimant has to provide evidence supporting their case. If it is sufficient then it is accepted as likely true. But if the evidence or claims are effectively refuted then the claim has failed and it is not accepted as true.
