The author has tried to place the reader, either above the peak of the events, or at the very depths of them, so that he can feel while reading as much as possible, similar to the feelings of those he reads about, and so that he can judge the course of the events whose details, circumstances, and circumstances were mentioned to him in an honest and balanced judgment. He has indeed succeeded in placing in the reader's hands a set of unique experiences full of facts and events in time and space, testifying to man's courage and his bold tendency to discover and investigate, and to the will implied in his nature to control the environment surrounding him. It also testifies to his resourcefulness in inventing what ensures He has the means to survive, and his willingness to sacrifice his life in order to achieve this goal if necessary. The book included a range of stories, regardless of historical considerations, because of the wonderful facts it contained that seemed like some myths, including some that record man's exploration of the world and his foray into the unknown.
