civilization

Our world can be the wonderful place, if we have a positive perspective. Our planet can be beautiful, if we like it.
Our civilization can be beautiful, if we like how it creates value for our personal life. All of those things can be very difficult, if we have a negative personal perspective about life and our history.

There is a very good book with the name "Sapiens" by Yuval Noah Harari. This book is about the history of the human civilization
on the planet earth. The "Sapiens" book does explain the steps of our human civilization. There are historic facts. Very interesting theories and a lot of interesting stories from the history of our planet.
