<HTML>Everyone without exception approaches a subject matter with a level of bias. We all operate in different worldviews.
Predictions will arise due to the results obtain from other sites and the patterns which can be seen emerging. What happens with a new site is excavated, or an existing site re-excavated and/or its materials re-evaluated, is that comparitive tests are done to see whether the predictive power of various constrasting theories is really up to scratch. If it isn't up to scratch then the evidence forthcoming devalues the strength of that particular theory and new hypothesis have to be formulated to explain and incorporate the new material. In this fashion science advances, although by its very nature we will never know the 100% truth. "Truth" in science is an elusive concept.
