Scientific knowledge has seemingly been prized by the inhabitants of every culture, known and unknown. Rock engravings, which may be as old as 60 million years, depict in step-by-step illustrations an entire heart-transplant operation and a Cesarean section. The ancient Egyptians used the equivalent of contraceptive jelly and had urine pregnancy tests. The cement used in filling Mayan dental cavities still holds after 1500 years.

No fabric is supposed to have been found until Egypt produced cloth material 5000 years ago. How, then, can we deal with the Russian site which provides spindle whorls and patterned fabric designs more than 80,000 years old?

Not only did the ancient Babylonians appear to use sulphur matches, but they had a technology sophisticated enough to employ complex electrochemical battery cells with wiring. There is also evidence of electric batteries and electrolysis in ancient Egypt, India, and Swahililand.

Remains of a metal-working factory of over 200 furnaces was found at what is now Medzamor in Russian Armenia. Although a temperature of over 1780 degrees is required to melt platinum, some pre-Incan peoples in Peru were making objects of the metal. Even today the process of extracting aluminium from bauxite is a complicated procedure, but Chou Chu, famous general of the Tsin era (265-316 A.D.), was interred with aluminium belt fasteners on his burial costume. full story
