In most areas of science, cases are built with supporting evidences. Evidence, it must be remembered, is data supporting a position. This data is often open for debate and discussion. Evidence does not typically prove a position but is information consistent with the position of the theory or claim.
As previously explained, even in the hard sciences some theories approach near-proof only with the accumulation and interlocking of multiple pieces of evidence. A single piece of evidence could be an anomaly, a singularity or even a coincidence. As the number of interlocking pieces increases, the strength of the proposition increases as well.
Critics frequently like to pull out the “biased Mormon” card when any evidence in favor of the Book of Mormon is suggested. They claim to prefer the conclusions of “objective” scholars — by which, of course, they mean “non-Mormon” scholars. This myth of “objectivity” will be addressed in coming months, but for now it should be noted that most scholars would agree that — especially in historical studies — there is no such thing as a completely neutral observer.
