THE CREATION STORY

- God created the Earth, the firmament and

everything therein. Under the Judeo-Christian
faith and traditions, it asserted that God
literally created man on the sixth day. And on
the seventh day God rested. There are
skeptics, however, who believed that the
creation story was symbolic. Whichever side
one believes is a matter of religious belief and
orientation.
