evidence confirms biblical depiction of Edom

Why not? We find indian camp sites that have been dated 13,000 years old. Perhaps not all of them, but then again, the appalcian mountains are not desert, which as a preserving quality.

That is the thing about science. Sometimes, people make changes/assumptions. These have to stand up to the scrutiny of peer review, to try to eliminate bias as much as possible. People will examine the evidence, methodlogy, and conclusions, and often challenge it. Hopefully, that filters out individual bias, and poor techniques.

Yet, sometimes, the absence of evidence OF something is evidence becomes increasingly the evidence of absence. The more one looks for evidence that SHOULD be there if the hypothesis is correct, and does not find it, the higher the probability that the hypothesis is incorrect.SOmetimes, other evidence can promote the absence of something. For example, when doing an analysis of the fish population in the Loc Ness, there isn't enough fish to be able to support even a small population of
a large predator. That is strong evidence against the existance of Nessie.
