...1 In the beginning Man created God; and in the image of Man created he him.
...2 And Man gave unto God a multitude of names,that he might be Lord of all the earth when it was suited to Man
...3 And on the seven millionth [day Man] rested and did lean heavily on his God and saw that it was good.
...4 And Man formed Aqualung of the dust of the ground, and a host of others likened unto his kind.
...5 And these lesser men were cast into the void; And some were burned, and some were put apart from their kind.

...7 But as all these things came to pass, the Spirit that did cause man to create his God lived on within all men: even within Aqualung.
...8 And man saw it not.
