Read the account of Cornuke and learn. You seem to have "contempt before investigation." There were also 12 pillars surrounding the site. (12 tribes?) Then you have to explain the scorched mountain - there is no scientific explanation for it. Got one? It seems the evidence is in support of the biblical account.
By the way, you are the one who tried to use "silence" as evidence that the Jews were never in Egypt--and I called you on it. It's an invalid argument. Period.
