A one-pager titled
Milestones in the History of Universe
that I prepared for an eight-year old kid.
It lists about ten most important events in the history of universe,
from my limited perspective. I should clarify that by
"agriculture revolution" I mean humans learning to grow food
and learning the concept of preservation of food (using salt).
Before agriculture revolution humans were hunters and gatherers.
By "civilization" I mean about hundred or more humans sharing their
work loads for a common goal. These led to societies,
and agglomerations of these societies led to empires (countries or nations).
