For centuries, people peered into the night sky, trying to understand what was hidden in his bottomless blackness. Many peoples imagined heaven with a huge opaque sphere, which covers flat earth, like a giant cap. Furious cosmic fire burns behind him, the reflections of which are visible at night through tiny holes - stars. It is curious that young children sometimes imagine the sky just that. Like our distant ancestors, they still lack knowledge to make a more true picture of the world.
