This is a very widespread illusion about the nature of historical evidence. It's almost never black and white.
I keep hoping we'll get a good debate started on Geni, but most people shy away from it because it's too hard to think about.
The genealogical proof standard is not -- as many people believe -- finding a clear and direct statement that someone was a child of someone else.
The Board for Certification of Genealogists defines the standard this way:
"Proof is a fundamental concept in genealogy. In order to merit confidence, each conclusion about an ancestor must have sufficient credibility to be accepted as "proved." Acceptable conclusions, therefore, meet the Genealogical Proof Standard (GPS). The GPS consists of five elements:
* reasonably exhaustive research;
* complete, accurate citations to the source or sources of each information item;
* tests—through processes of analysis and correlation—of all sources, information items, and evidence;
* resolution of conflicts among evidence items; and
* a soundly reasoned, coherently written conclusion.
"Each element contributes to a conclusion's credibility in a different way, described in the table below, but all the elements are necessary to establish proof."

Notice that in legal terms, this is similar to "preponderance of the evidence" or "more likely than not". It is not "beyond a reasonable doubt".
