Conventional wisdom has it that the cradle of human civilisation was China or Mesopotamia (now Iraq) - although much of the proof has been destroyed by construction or war. Once upon a time, just about anyone could claim their object, building or man-made mound was the oldest in the world but the advent of radiocarbon dating has blown such pronouncements out of the water. What we do know now is that Stonehenge is but a whippersnapper in the megalithic world, and culinary tools were made before apes had fully evolved into homo sapiens.

Here's our guide to the earliest known endeavours of humankind, from the stone age to the industrial revolution and beyond, that can still be seen - until they're disproved by the next techno-historian.
