shimrod,- 1st as dmcg reminded you, because something is not found is not proof that it was not there. I should add that darwinists lean heavily on that, and talk about a Cambrian explosion, for example.
2nd...if lions were in Israel but left no remains, why insist that camels must.
3rd..carbon dating has not always been accurate, eg dating recently formed rocks as millennia old.
4th...and perhaps most pertinent, camels were not prominently resident in Israel in earlier times, I think. the biblical list kindly provided by Monique for your benefit just about in every case referred to action outside israels borders. Israel was on major trade routes in the ancient east but probably not native to Israel, and perhaps rarely kept therein.
I hope this may help your impartial scientific research.........
