Thousands of years ago, people in the Middle East found sticky black oil seeping up in pools through the ground from vast underground reserves and used it for many purposes, including waterproofing their houses. In ancient China, people used iron- - tipped bamboo drills to drill into the earth for saltwater, but found oil and gas as well. They burned the gas under big pans of the saltwater to extract the salt.
