The manifested cosmic nature is created at a certain period by the will of the Lord, it is maintained for some time, and finally it is annihilated by His will. Thus He is the supreme will behind all activities.
Of course, there are atheists of various categories who do not believe in the creator, but that is due only to their poor fund of knowledge. The modern scientist creates sputniks, and by some arrangement or other they are thrown into outer space to fly for some time under the control of a scientist far away. All the universes and the innumerable planets within them are similar to such sputniks, and they are all controlled by the Personality of Godhead.
In the Vedic literature it is said that the Absolute Truth, the Personality of Godhead, is the chief among all living personalities. All living beings, from the first created being, Brahmā, down to the smallest ant, are individual living entities. And above Brahmā there are many other living beings with individual capacities. The Personality of Godhead Himself is also a living being, as much an individual as other living beings. But the Supreme Lord is the supreme living being, with the greatest mind and the supermost inconceivable energies in great variety. If a man's mind can produce a sputnik, we can very easily imagine that a mind higher than man's can produce wonderful things far superior to man-made sputniks.
