In the grand scheme of things, there must be an explanation to the arrangement of the cosmos, the sun, the galaxies, the stars, planets and their continued journeys around or past each other and without a collision or 'accident'. A deity must be somewhere up there or below, who is looking at us secretly and watching every move we make and using some genius method to let the moons spin around planets, planets around the sun and holding the sun in the vastness of space.
The sun, the only star in our solar system. The earth moves around this star, the sun. The earth has a moon moves around it. For the moving of these three, namely the sun, the star; the moon and the earth night, day, month and year happen one after another.
