If there are still people on this thread wondering what my position is : It's this.You're ranting again. There's no need to yell, or to try and insult other posters (though I don't think anyone left in this thread is a Christian, you're... let's say 'preaching to the choir'), or to bring up religious arguments unrelated to this thread. I'll summarize my position again, and hope you won't resort to yet more conspiratorial accusations.
The burden of proof is on whoever makes a claim, whether it is positive or negative.
All this means is that one should be able to support one's claim. Perfect logical proof is rarely needed outside of mathematics. Pointing to a lack of evidence for a positive claim supports the corresponding negative claim.
If someone claims Jesus came back from the dead the burden of proof is on the claimant. If someone claims the resurrection could not have happened the burden of proof is on them.
Pointing out that the supposed resurrection is impossible in light of everything we know about biology is sufficient evidence for this claim. If the other party wishes to counter this by stating that it is biologically possible after all, or that some magical exception was made, this new claim is theirs to support.
Take note that this paragraph is purely about where the burden of proof rests in abstracto, when a claim is made. I am not claiming every crackpot hypothesis needs to be disproven by someone who does not believe in its validity.
Disbelieving an unevidenced claim does not shift the burden of proof. If someone claims Jesus came back to life, responding: 'I don't believe that, can you prove it?' is not a (negative) claim, it's a request for evidence. So yes, it's not up to unbelievers to disprove the resurrection, or provisionally accept it until they do. In concreto, the onus is on the believer.
Thanks, Porpoise.
