cosmicsolutions Discover The Mystery Of Ancient Civilizations

"The Indus Valley Civilization has yielded evidence of dentistry being practiced as far back as 7000 BC. This earliest form of dentistry involved curing tooth related disorders with bow drills operated, perhaps, by skilled bead craftsmen.

The reconstruction of this ancient form of dentistry showed that the methods used were reliable and effective. Cavities of 3.5 mm depth with concentric grooves indicate use of a drill tool. The age of the teeth has been estimated at 9000 years."

"As early as 6,000 BC farmers used irrigation to control floods and to guide water to areas where they could grow barley, even in areas where there was not enough rainfall. The ancient Mesopotamian also were among the first to use water caches to store excess water for times of drought.

This basic skill, of bringing water to crops to expand arable land and increase food production, is still a fundamental skill of farmers around the world today."
