Impossible to prove a negative? I'm afraid you are sadly mistaken. I am not going to belabor my comment with a lesson in logic. But, I do suggest you read more about Agnosticism before you use ignorant supposition as a replacement for valid argumentation. Here's a link. And by the way, I am agnostic.
Probably the easiest example is to prove that the square root of a negative number cannot exist and is thusly an imaginary number. Sqrt(-1)=i. For a more detailed discussion search wikipedia for "Proof by negation". You will find the discussion to be interesting, I would think.
Maybe that's because it's not comprehensible? I finished secondary school at 14, so I'm self-educated, and I haven't come across whatever you're talking about. It's probably not beyond my comprehension if I could be bothered, but I'd be happy if you'd show me how it's possible to prove a negative by meeting my request about santa. The tooth fairy or the easter bunny would also be ok if you can manage it: I'm beginning to think you're all talk and obscure references - if it's so easy to prove a negative, let's see you do it.
I wasn't being facetious and philosophy is one of my "things", as is your propensity for being patronising in place of actually addressing the question I asked earlier.
It is easy to prove a negative. For example, any negative number times itself will always be positive. (Minus times a minus = plus) Any positive number times itself will always be positive. (Plus times a plus = plus). The only way to get a negative product from multiplication is to multiply operands with unlike signs. Therefore, square roots of negative numbers are not possible, unless they are redefined as imaginary. See http://en.wikipedia.org/wiki/Imaginary_number
At this point, I am saturated with complete frustration. Insisting that this demonstration of the logic of disproof is not valid unless it includes Santa, the Easter Bunny, or the Tooth fairy would get you kicked out of any Philosophy class at a public university, along with an "F" for the semester. Serious academics would only judge your lack of rigor as either facetious or a display of capricious immaturity.
Come and let us discuss atheism.

It was actually a dictionary definition, I don't do ignorant suppositions, nor will I trade insults with you as I prefer rational argument.
Please let everyone but especially me have an example of how to prove a negative: for example, prove to me that Santa doesn't exist

I am sorry that this material is beyond your comprehension. You are discrediting yourself with facetiousness. Maybe philosophy is just not your thing.
