Timeline of Major Human Progress

(Scientific, Technologies, Religious Manifestations and UFO Sightings)

Modernization and Humanity are Accelerated by Provision of Free Knowledge

From Wikipedia, the free encyclopedia, Encyclopædia Britannica, Inc. CD of 2000 and the UFOs sightings from various mentioned sources

Note: Dates for inventions are often controversial. Inventions are often invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a practical form. Where there is ambiguity, the date of the first working version of the invention is used here.
