Egypt's geographical isolation and the unique geography of the Nile Valley are thought to have been responsible for its long existence. Because of this military control, astronomical concepts in Egypt became so ingrained and inseparable from everyday concerns that they became an integral part of Egyptian life. As your gaze rises to the horizons of Egypt, you can see the movement of the stars and planets: the climatic conditions never change, ensuring a similar seasonal cycle each year. Besides this, Egypt also enjoys a cloudless sky almost all the time and a location in latitude that allows even the most densely populated regions of the starry heavens to be viewed.
