how did i get here

How did I get here? To answer this question, the book traces its history from the Big Bang (theory that explains the origin of the universe) to its birth. The task is not easy, but, with great grace and simplicity, our author begins to present the formation of the stars, the solar system, the planet Earth, the first living beings to come to you. In the course of reading, the reader, who is also a character, discovers that all human beings have the same origin. Thus, there is no denying the common destiny of all of us, and the need to work together to preserve our species and the planet we inhabit.
