The Kangla, the First Dry Land in the World

According to the puyas a, the kangla was the first dry region in the entire world. Some pottery has been discovered there that is 17 to 21 thousand years old. The ningtoja dynasty may have started r on 36 a d. So i haven't found, from my very cursory research thus far, any evidence of this claim. I wonder what the great historians in the monipor university are doing? Why nd wyren the researching this?
