assuming you're talking about evolution, i'd like to hear one of these many ways. also, just as a warning, i may or may not entertain with a response, not because i'm ignoring you, but because my original terms were that i will attempt to debunk challenges that creationism is true, not evolution. the latter is a whole another can of worms.There's plenty of ways to prove Darwin was wrong.
1. the burden of proof is on the positive. proving something isn't or doesn't is a negative. the DEFAULT condition is that there is no god so therefore, it is the theist's sole responsibility to prove that there is god. it's like going up someone and saying that there is an invisible cat in the room right now, and if that someone objects, you tell him that's he wrong because he can't prove that there is an invisible cat. in fact, this can be said with ANY negative:AFK, Here's a question, "Prove God doesn't exist"
person A: the loch ness monster exists.
person B: i disagree. it doesn't exist.
person A: prove that it doesn't exist.
person B: ######?
person A: see, since you can't prove that it doesn't exist, the loch ness monster exists.
person B: ######.
2. proving this negative is impossible. there is no way to check every corner of the universe for god, and even if you could, while you are checking one corner, he might have just moved to another. some theists might jump at this point to proclaim victory, but this resembles NOTHING like a victory of any sort. proving the non-existence of god is just as impossible as it is to prove the existence of god. the bottomline still remains: there is NO REASON whatsoever to believe there is a god.
