Right away we establish that the Mythmakers are not atheists. They simply do not know what god is, or even whether there is a god or gods. After all, they are called Mythmakers for a reason. Myth always incorporates ideas of the supernatural. The supernatural answers a need evolved in the genetic structure of humanity -- the urge to explain the unexplainable, an urge that is often answered by science as humans advance intellectually. Ultimately, however, there is always something that science cannot unexplain. One of the traditional attributes of god is that he/she/it is unknowable. If you can never know what this entity is, you cetainly can't demonstrate anything about it using scientific methods. You can neither prove nor disprove the existence of god or define its nature.

5. Humans will never succeed absolutely in achieving these goals; nevertheless striving for right action is its own purpose.
