List your picks, and why.
These are the inventions and developments that made our civilization possible.
I’ll start out with three.
Fire. Enables humans to survive in freezing climates, cook, and work metal.
The wheel. You can have a civilization without it, but only at a primitive level. Makes transportation of people and goods possible.
Written language. History itself could not begin until the dead could communicate with the living and pass along all they have learned.
There are many others to list, but why should I have all the fun?
