Because the burden of proof is always on the person making the positive assertion. You say there is a god–the burden of proof is on you. I say there is no god–I have nothing to prove. After all, you can’t prove a negative.
If I said there is no life on any other planet in the universe, would you say I had no obligation to prove that?
I think that’s a good point, Charles. Where it fails for me, in that example, is that there is life on Earth, and there’s no reason to think that’s unique. But that’s a separate issue. On the other hand, if you said there’s no such thing as Shiva, I would not expect you to provide evidence.
You asked a question. I gave you an answer that is actually commonly accepted–the burden of proof is on those who argue the positive position. Thus, you couldn’t actually prove that there was no other life in the universe. You agree with this, I assume. If, on the other hand, I said there was, definitely, other life in the universe, I’d need to provide evidence. I could say there’s a good probability, and provide some sort of explanation; but if I wanted to argue outright that
there is definitely life out there, I’d need to provide positive evidence. You, on the other hand, don’t need to. In fact, you can’t–such a thing can’t be proved. That doesn’t mean I need to accept that. I could have hope. I do believe there is life in the universe other than on earth. But I can’t prove it.
So, you asked your question, though. The answer truly is that
the burden of proof always lies on the individual making the positive assertion. That’s why that doesn’t work. I can not prove a negative. It’s not humanly possible. You can prove a positive, so the burden is on you.
