I am in need of a link that, in layman's terms, describes why you cannot prove a negative. I though it was here on ST.NET, but I am not finding it. Any info would be greatly appreciated.

Because to be certain you have proven a negative, you actually have to be positive.

LOL, I'm serious tho.

If you prove a positive of a situation where it is 100% sure that it is either positive or negative, you prove the negative is not the case.

I am having trouble articulating why the above statement, from a scientific/logical standpoint, is false. I believe I remember Mike having a nice article regarding the topic at hand, but I am unable to access his creationtheory.org website due to it being blocked.
