I believe TNFD or
The National Freethought Day is tomorrow
The correct order of events from the past to the present is:
B; C; D; A
When humans first started to appear they had yet to figure out how to farm or fish. However they knew how to hunt animals using spears and such. They also were gatherers because they gathered berries. Later in the human race farming and fishing came into play. So I say A. Hunters......Gatherers.
It’s B because I looked it up lol
