When a cycle comes to a close, a new one is inaugurated, and the previous cycle, on account of the momentous events which transpire, vanishes so entirely from memory as to leave behind no record or trace. Thus, as you are aware, we have no record of twenty thousand years ago, even though we established before through rational arguments that life on this earth is very ancient—not one or two hundred thousand, or even one or two million years old: It is ancient indeed, and the records and traces of ancient times have been entirely obliterated.
