Archeology can only prove the existence of artifacts unearthed, not disprove that which hasn't been found. Yet that has not stopped some archeologists from making bold assertions. She found no evidence, and concluded on that basis that the Bible was false. The problem is that Kenyon dug only one small section of Jericho, and based her conclusion on that limited information. Today, though the controversy lingers, many archeologists claim there is indeed clear evidence of inhabitation in Jericho from the time of Joshua.
Archeology is a new science, and the record is far from complete.
We have only begun to scratch the surface. The Times writer makes other mistakes, such as reading the Biblical text without the accompanying Talmudic explanation. The preeminent Biblical commentator, Rashi, explains that after the Egyptians drowned, the sea threw them onto the shore, so that the Jewish people could be relieved at the knowledge that their enemies would no longer be in pursuit. We would disagree. The truth of the text is precisely the point.
