Sooooo, boring. What's wrong with you, people? **** human history. So short and almost predictable.
Most interesting periods in history:
-Hadeon eon, 4.6 Billion years ago, the formation of Earth and the first living creatures.
- Paleozoic Era, Cambrian Period, 542 Million Years ago. Diversification of life; hard-bodied creatures emerge.
-Mesozoic Era, Triassic Period, 251 mya. First mammals
-Mesozoic Era, Cretaceous Period, 146 mya. The K-T Impact: the end of dinosaurs; mass extinction.
-The time of the invention of the wheel.
