Hear my story:
There is a huge haystack. Jack and Jill have been told that there is a needle in the haystack. Jack believed that there is a needle in the haystack. Jill believed that there is none. The haystack is so huge that it is impossible for Jack to find the needle. The haystack is so huge that it is impossible for Jill to prove that there is no needle. Both have no proof to support their beliefs.
