75,000 years ago early humans built a stone calendar that predates all other man-made structures found to date. This ‘African Stonehenge’ has for the first time created a link to the countless other stone ruins in southern Africa and suggests that these ruins are much older than we thought.

get the oldest land mass map you can find; where the theory of the continents being one whole continent is shown and look at that last pic again. weird
By the 5th millennium BC these peoples had fashioned one of the world's earliest known archeoastronomical devices (roughly contemporary to the Goseck circle in Germany and the Mnajdra megalithic temple complex in Malta), about 1000 years older than but comparable to Stonehenge (see sketch at right). Research suggests that it may have been a prehistoric calendar which accurately marks the summer solstice.

If this report is right (and I have my doubts) it just reinforces that mankind had a need for "clocks" knowing what day it was, or more pointedly, which season and what plants and animals were doing was critical.
Survival depended on knowing when they could harvest or the best time to move to a new area.
