I have studied quite a bit about Abraham, how he started out in Ur and traveled the whole furtile cresent around to Egypt and them back up to his final destination in Isreal. He was a very well educated person. Back then he would have been considered a priest, but he would have learned all knowledge known at that time. There was a lot of error mixed in with the Chaldean knowledge, so God wanted to purify a people onto Himself and Abraham was choosen. The Hebrews were to be a people seperated onto God, to be a testimony to all the nation of the truth.
Most of the history of this area does go back 100 years. It would be wonderful if the area were secure enough so that the archeologists could get in there and do research. But the only way to study the area is to take students in there during the summer. Needless to say, no professor in his right mind is going to take a group of students into that part of the world right now.
It looks like about the best we can do right now is to secure the area to keep the treasure hunters out. They do not document anything and any artifacts they find lose their context and are greatly depreciated in value because of that. I do not have any hope for any serious studys to be done in this area untell the 1000 year reign of Christ, when I think that information will be greatly increased.
